The month of March is when Spring begins. For many, this March was the beginning of something much more sinister. We were terrified, and rightly so, by the emergence of the novel coronavirus COVID-19. Now, half a year later, not only are we still fighting the virus, we are also fighting the wave of people who believe that the virus is a hoax. But even those of us with good intentions have created new evils.
This Spring brought with it the familiar sight of brightly coloured patches appearing in our fields and meadows. You must have seen them, the brilliant blues and pure, snowy whites. Look closer; they are not flowers. Every day, we are throwing away millions of disposable masks and gloves, many of which end up contaminating the natural world.
If you don’t have a few cloth masks by now, you are behind the game. Not only do they save you money in the long run, they are also better for the environment and more comfortable. It has been shown time and time again that masks are very effective at preventing the spread of respiratory illnesses. I’m sure you know this, but you should be wearing one every time you are in public. That much is no longer up for debate.
The same, however, cannot be said for gloves. There is a real chance that we are throwing billions of gloves into our rivers and seas for no reason. The WHO,HSE and CDC have all released statements which tell us that there is no evidence that gloves are effective in preventing the spread of COVID-19 in the general public.
Medical professionals are constantly touching contaminated surfaces and coming into contact with infected people. They are truly on the front line. For the most part, medical professionals only use gloves when there is a risk of coming into contact with a patient’s bodily fluids. Other uses would include surgery or if there is a chance of injury, for example, from a needle. Unless you are taking care of someone who is either vulnerable or infected with COVID-19, there is no benefit to wearing them.

What’s more, medical professionals have been trained in how to effectively use, remove, and dispose of gloves. They know how frequently the gloves must be disposed of, and they know to be careful what they touch when their gloves may be contaminated. In other words, they are aware that it is not in any way a substitute for hand hygiene. In the medical profession, the use of gloves is absolutely necessary. For everyone else, however, it is a somewhat different story.
When you touch a contaminated surface, the virus transfers from the surface onto your hands. That is true whether you are wearing gloves or not. It doesn’t matter whether the virus is on your skin or the gloves. In both cases if you touch another surface, you transfer the virus to it. In both cases if you touch your eyes, nose or mouth, you can become infected.
When you take off a pair of contaminated gloves, the virus can easily transfer onto your skin. It is recommended, then, that you wash your hands every time you remove a pair of gloves. Do you see the problem here? It is cheaper, better for the environment and in fact more effective to simply cut out the middleman and wash your hands. You are adding an unnecessary extra step to the process; one which contaminates our rivers and seas.

Wearing gloves gives people a false sense of security. We think we are protected, but in fact we are just as vulnerable to infection. If you are not wearing gloves, you are more likely to wash or disinfect your hands because you know the virus might be on your hands. When we think we are protected, we become complacent. What’s more, when you contaminate a pair of gloves and then throw them away, you have created a new surface for the virus to live on. That creates a new risk for the sanitation workers who have to pick the gloves up off the ground and dispose of them. The same problem does not happen when you wash your hands instead.
Another consideration is that when the general public uses vast amounts of medical gloves, they create a shortage for the people who actually need them: medical professionals. As was the case with hydroxychloroquine, uninformed panic has caused people to unnecessarily deplete necessary resources, to the detriment of doctors and hospital patients.
That is aside from the better-known impacts of plastic pollution, like those which occur when marine animals ingest or are entangled in plastic. If for whatever reason you are still using disposable face masks, make sure to cut the straps to prevent entanglement.
Not only do animals ingest plastics, we ingest them too! A recent study tested 47 tissue samples from human organs and found that every single one of them contained plastic. We are creating a massive crisis for the future in the name of halting the current one, and it is not even helping. As good as our intentions may be, the use of gloves to combat COVID-19 may well be costing more lives than it is saving. If that’s true, why do it?
People are wearing gloves because they are scared and because they want to do everything they can to slow the spread of this deadly virus. That is admirable. We should be scared, and we should be doing everything we can to help. This virus is very real and very dangerous. The problem is that gloves likely don’t help, and they create new problems.
If you feel you must use gloves, you have to make sure that you change them as frequently as you would wash your hands. Do not touch your face while wearing them and be ready to take them off the moment you think they have been contaminated. The best way to remove them is to roll them down from the wrist, since this turns them inside-out, reducing the amount of contact between your hands and the surface of the gloves. You also need to make sure that you wash your hands when you take the gloves off or risk contaminating your hands.
If you walk at night along an open marsh or riverbank, you may well come across an incredible animal. This mammal with two arms and two legs is agile enough to chase and catch a fish underwater and smart enough to use tools. There are as many as 13 distinct species of otter, but I will be focusing on two: the sea otter and the Eurasian river otter. Sea otters recently captured the hearts of millions when they were featured on David Attenborough’s Our Planet. In this piece, I will be looking at what makes otters so special, and what makes them so damn endearing.
Beginning in around 1741, Russian hunters brought sea otter populations to their knees in order to sell their warm, dense fur. In the process, they completely exterminated the Stellar’s Sea Cow, a close relative of the manatee which measured 9 meters in length. That’s about half a bowling lane or a little over 6 Danny DeVitos in case you were wondering. Sea otter populations rebounded from just 50 individuals in 1914 to around 3,000 animals today. Some populations, however, are once again in decline as a result of oil pollution and habitat loss. They are currently listed as endangered on the IUCN red list.
Despite being solitary creatures, these otters have a pretty complex social life. Males (called ‘dogs’) have a rigid territory which they defend from other males, while female territories overlap. It is thought that females (called ‘bitches’) share a group range, but that each individual has a core area where they spend more than half their time. Essentially the only reason males and females meet is to mate. The male contributes nothing but sperm to the raising of young, despite cubs taking up to 13 months to become self-sufficient hunters. The nest in which the mother raises the young is known as a ‘holt’.
Otter populations have declined significantly across Europe, with the species recently becoming extinct in the Netherlands. Ireland is left as one of the last strongholds for the Eurasian Otter. Their decline was linked to the use of organochlorine pesticides, highly toxic chemicals which have made their way into the aquatic food chain. Organochlorine pesticides include DDT, the chemical at the heart of Rachel Carson’s seminal 1962 work Silent Spring. The fight against organochlorine pesticides was the catalyst for the birth of the environmentalist movement, and it is easy to see why.

Abbeyleix bog in Co. Laois is a rare example of a bog that has not been utterly destroyed by industrial peat extraction. Many of the peatlands I saw from my window on the bus down here were not so lucky. The barren and lifeless landscape of bogs that have been stripped bare is a common sight in the Irish midlands, and it is becoming more common every day. Abbeyleix very nearly met the same fate back in 2000. If it were not for the dedication and quick thinking of the community, the thousands of species in the bog would be homeless and hundreds of thousands of tonnes more carbon would be in the atmosphere instead of in the ground where it belongs.
Bogs and Irish culture have been intimately linked for centuries, cropping up in everything from our traditional songs to the work of our most beloved poets. They have provided us with energy, clean water, jobs and a home for our wildlife. Globally, degraded peatlands account for a quarter of all carbon emissions from the land-use sector despite covering only 3% of the land. They also contain 30% of the world’s soil carbon; that’s twice as much carbon as is stored in all the world’s forests. It is estimated that more than 80% of Irish peatlands have been damaged in some way.
Peat forms because the water-logged and acidic conditions of a bog significantly slow the decomposition of bog mosses, also called sphagnum, causing a build-up of organic matter. Emissions from peatlands don’t just come from the burning of the peat; they also come from drainage. When the level of water in a bog (known as the water table) is reduced, this exposes more of the peat to the air. In this dry, oxygen-rich environment, the peat decomposes, releasing all that carbon back into the atmosphere.
Despite owning only 7% of Irish peatlands, the organisation primarily responsible for the industrial extraction of Irish peat is Bord na Móna, a semi-state company which was set up by the government in 1934 under the name ‘the Turf Development Board’. Since the inception of Bord na Móna proper in 1946, the company has been responsible for the development of 80,000 hectares of Irish bogs. Back in 2016, Bord na Móna rebranded themselves with the slogan ‘Naturally Driven’ and tried to position themselves as environmental stewards. The journalist John Gibbons called this campaign “profoundly, irredeemably dishonest” and “an exercise in cynicism”. He also quoted An Taisce as saying “We suggest they drop their new ‘Naturally Driven’ slogan and replace it with the phrase ‘Profit Driven’. Then Bord na Móna would at least be able to sell its business plan with a straight face”.
Abbeyleix bog had been owned by the De Vesci family since the early 1700s. In 1987, Tom De Vesci, who had previously attempted to have the bog designated as a heritage site, was coerced by Bord na Móna into selling the bog. “I was approached many times by Bord na Móna to sell it after my father died in 1983 and I always refused” Tom said in an interview. “But eventually I was informed that Bord na Móna would be taking ownership via a compulsory purchase order at a somewhat lower level of compensation than I would get if I sold it ‘voluntarily’ a few weeks earlier”. In 1989, Bord na Móna cut 66km of drains into the bog in preparation for future peat harvesting.
On Thursday, 20th of July 2000, Chris Uys, a member of the Heritage Company and now development officer for the Community Wetlands Forum, met with Jimmy Dooley of Bord na Móna to discuss plans for a walkway through the bog and to inform Jimmy of concerns regarding its development. The following day, locals noticed unfamiliar pieces of machinery on the bog, which had been delivered to the site by Bord na Móna overnight. Chris Uys raised the alarm in the community that development of the bog was about to begin. That Sunday, local resident Gary O’Keeffe parked a crane in the entrance to the bog under the guise that it had broken down during a bird-watching session in order to keep the rest of the machines out of the bog. By Monday morning, at least 50 people had gathered at the entrance to protest the development, with numbers swelling to around 100 by lunchtime.
After much pressure from the community, Bord na Móna finally agreed to carry out an Environmental Impact Assessment (EIA) in April of 2001. They found that the Abbeyleix site was of “little or no conservation value”, an assessment which both the Abbeyleix community and the Irish Peatlands Conservation Council (IPCC) considered “incomplete and inaccurate”. An ecologist by the name of Doug McMillan was invited to carry out an independent assessment of the bog. Having only surveyed 20% of the land, Doug had already found over 500 species, and could reasonably conclude that the bog was home to thousands of species, including a butterfly which was protected by the EU. If Bord na Móna really had carried out an EIA, they had either done a poor job or they had lied about the results.
In 2002, An Bord Pleanála found that Abbeyleix bog was not exempted from the requirement for planning permission. This was the first time in Irish history that a peat development went through the planning permission process. Bord na Móna, in true form, took high court action against both the Laois County Council and An Bord Pleanála. In 2008, an ecologist by the name of Jim Ryan carried out another survey, finding that only 1% of the raised bog was still intact and forming peat. I am stunned when Chris tells me that, like in Abbeyleix, only 1% of active raised bog in the country remains. In other words, we have degraded 99% of carbon-rich raised bog nationwide through drainage and peat extraction. In April of 2009, more than 20 years after they were cut, work began to block the drains in Abbeyleix. In April of 2012, the Abbeyleix community signed a lease agreement which meant that the bog would be in their control for the next 50 years, provided that it was primarily used for habitat restoration. David had beaten Goliath.
I met with Chris Uys in the lobby of the picturesque ‘Abbeyleix Manor Hotel’ on the outskirts of the bog. He has brought with him a textbook on peatlands and a folder packed to the brim with documents. When I ask him why peatlands are so important for biodiversity, he tells me that “the interesting thing about the biodiversity in peatlands is that the combination of plants and… the way they interact has a wider role to play than just purely the biodiversity that is there because it helps to retain water content, it has to do with carbon sequestration, and it supports other ecosystems”. He tells me that bogs are very important for breeding birds and that they link different ecosystems together like a natural corridor.
A walk through Abbeyleix bog feels like a walk through the history of this country. There is a calm here that soothes your aching bones like a hot bath. This is what is known rather robotically as a ‘cultural service’; one of many ‘ecosystem services’ provided by bogs like Abbeyleix. These somewhat stomach-churning terms are used by some environmentalists as an attempt to reframe the ecological crisis we have caused in the parlance of capitalism and thus convince business and industry to act. Gazing out over the endless beauty of this ancient landscape, I can’t help but think that it is downright insane to try and put a price on something that existed for so very long before our self-centred species ever dreamed up the concept of money.
Back in 1997, peat fires forced both Singapore and Kuala Lumpur to close their airports for several days. The peat in question was burning over 1,000km away in Indonesia. Scientists have estimated that the CO2 released during this one fire was equivalent to 13-40% of the mean annual global emissions from fossil fuels. The carbon is not the only issue; the vast quantities of smoke released by the fire had serious effects on health, with studies showing decreased lung function in children who were present during the event. According to a study in Archives of Environmental Health, 527 people died in 2 months as a result of the smoke, with 58,000 cases of bronchitis and 1 and a half million cases of acute respiratory infection reported. Fires like this have happened periodically over the last few decades, with one 2010 event in Russia leading to carbon monoxide levels in the capital that were 6 times the maximum acceptable level.
To the Irish, this all may seem like a distant threat, but were the Wicklow bogs to catch fire, the prevailing wind would carry all that lethal smoke right into the heart of Dublin. John Reilly, the head of the renewable energy branch of Bord na Mona, told me in an interview that “the biggest risk of wildfires is not posed by active peat production areas on drained peatlands, but rather the risk is high on virgin peatlands which are generally covered in vegetation such as gorse and heather”. He said that the major concern when it comes to fires was actually stockpiles of cut peat.
DCU-based peatlands expert John Connolly tells a slightly different story. “In one way he is right that the risk of fire (i.e. fire starting) on a drained industrial peatland may be less if all vegetation is removed. However, a lightning strike could start a fire and in that case drained peatlands are much more vulnerable than virgin (i.e. wet) peatlands”. Dr Connolly sent me a link to a 2016 study in ‘Nature’ which states that “the high burn severity of drained tropical/temperate peatland fires suggests that large-scale peatland drainage and mining in northern peatlands over the last century has also likely made managed northern peatlands more vulnerable to wildfire than natural (undrained) peatlands”. While there is an element of truth in what John Reilly told me, then, it seems that it was not the whole truth.
In 2006, an area of dried and cut peat the same size as Abbeyleix bog caught fire in the Irish midlands, leading to the evacuation of several Longford residents. While it was the stockpiles that caught fire rather than a bog itself, the incident shows how damaging peat fires can be. Smoke from the fire travelled 10 miles north. One Rooskey resident who had suffered from respiratory problems in the past was quoted in the Irish Times as saying “at the moment I am closing my windows and hope that will be enough”. A 2002 study of the Indonesian haze disaster, however, suggests that staying indoors only gets you so far in a situation like this.
They found that indoor concentrations of particulate matter were about half of what they were outside. That was a form of particulate matter known as PM10 because the individual particles are 10 micrometers or smaller in diameter. They could not find any difference, however, in the concentrations of fine particulate matter, or PM2.5, which are particles 2.5 micrometers or less. The researchers said that “perhaps the size of particulates was so small as to travel and intrude into any space; the concentration of pollutants was extremely high, and the indoor environments of buildings in Indonesia were rarely exempt from these pollutants”.
When asked about Mr Reilly’s claim that the presence of vegetation increases the risk of wildfires, Chris Uys replies that “from that point of view yes, that is so. But if you are talking degraded peatlands, degraded means that you have dried. For me, there is a higher risk… when the peat below the surface is dry and there is an ignition of anything above, it starts to smoulder underground as well”. Chris tells me that Abbeyleix has suffered from this very problem; “we had a fire at one stage, and you could just see smoke. On nearer investigation it was actually starting to simmer underground. It just keeps going”. While vegetation fires on the surface are manageable, the dried peat below can keep burning for a very long time and release a lot of carbon before it is extinguished.
Thankfully, Bord na Móna have been trying to get out of the peat business for over a decade, with over half of their revenue coming from non-peat-related activities in 2019. John Reilly, who has been doing excellent work building renewable energy infrastructure with the company, tells me that “Bord na Móna developed the first commercial wind farm in Ireland back in 1992, on a joint venture basis with the ESB, so we have some considerable experience in the sector”. They also announced last year that they were closing 17 of their active bogs, with the remaining 45 bogs to be closed within 7 years. However, some have said that this amounts to greenwashing, since the planned closures are of bogs that have been exhausted and are no longer profitable. As UCD peatlands expert Dr Florence Renou-Wilson put it in an interview with the Guardian, ““It’s a bit of a smokescreen. It’s all revenue-driven… they’re are all done and dusted”.
Bord na Móna is not the only company extracting Irish peat, though it is the largest. A company called Harte Peat has come under fire recently for carrying out large-scale peat extraction without a license in the Derrycrave bog in Westmeath. Photos released last year by ‘Friends of the Irish Environment’ showed that Harte had been cutting the peat right down to the mineral layer below, leaving almost no possibility of recovery. Peat that had formed at a rate of about 1 millimetre a year until it was several meters thick was stripped down to the bone in the geological blink of an eye, depriving animals of their homes and future humans of their right to security. This tragedy has played out countless times across the country over generations, leaving us with little more than a silhouette of the beautiful and important landscapes which once dominated the Irish midlands.
The degradation of Ireland’s peatlands doesn’t just threaten our health, it also threatens our wallets. New regulations require that we start reporting the emissions from our peatlands to the EU from 2021. Ireland is already facing hundreds of millions of euro in fines for failing to meet our emissions targets and this will bring us further off target. Chris tells me that “We were fined 150 million for this already… and we’re gonna be fined again until these people stop… Bord na Móna don’t get fined. It’s the government that gets fined. They merrily go on. They can go on for another 30 years if the government allow them. But we get that fine”.
When asked to what extent Ireland will be able to cope with these changes to EU law, Dr Connolly tells me that “the government and the EPA have made some investments in funding research and research infrastructure over the past few years. These investments will allow scientists to provide some of the detail that is required in the legislation, however much more investment is needed in research, infrastructure and rewetting/restoration as peatlands in Ireland are severely degraded and emissions are unknown in many areas”. But does this mean more fines for the Irish government? “It depends. If peatland emissions can be reduced to zero by the start of the 2026 reporting period, then no. However, current emissions are estimated to be about 11 million tonnes of CO2 … The reduction of these emissions to zero over the next six years will be very challenging.”
I ask Chris if Abbeyleix bog became a net source of emissions following the drainage and, if so, if it is back to being a net sink. “Possibly we are not a net sink yet… the higher the water level the less carbon emissions,” he tells me. “Then it gets to a point where it changes and it starts to give out methane emissions. There is a sweet spot where you have the least emissions. The other problem with degraded peatlands is that if you don’t have vegetation formation, (sphagnum), then it does not negate the methane”. The blocking of the drains has not been in vain, however. Whereas only 1% of the active raised bog remained in 2009, Chris reckons that as much as 10-15% has recovered in the intervening decade.
It takes time for peatlands to regenerate; all the more reason to block as many drains as we can as soon as we can. The light is beginning to fade from the grey clouds overhead as I slip and slide across the wet wooden walkways. The first few drops of rain begin to fall once more on the mounds and ditches of Abbeyleix. This beautiful landscape serves as both a cautionary tale and a beacon of hope. It showcases the terrible consequences of degrading our bogs, but is also a reminder that with elbow-grease, dedication and time we can undo some of the wrongs we have inflicted on the natural world.
Why do we cut our grass? The short answer is that we think it makes our gardens look neat and respectable. What would the neighbours think if our grass was long and full of weeds? What this kind of thinking fails to consider is the massive toll that lawn mowers have on local wildlife. All ecosystems are fragile and vulnerable to devastating chain reactions. By reducing the diversity of the plants on your lawn, you greatly reduce the hospitability of that environment for insects like bees, beetles and butterflies. This, in turn, has an effect on the food supply available to birds and small mammals. Some animals like mice and hedgehogs are often killed directly by the blades of mowers. On top of all this, most of us cut the grass with either petrol-powered or electric mowers, both of which hasten and intensify climate change, the greatest threat currently facing people and animals alike.
Humans have an obsession with shaping and controlling the world around us. Vast tracts of land are occupied either by our urban environments, crops or livestock. In the suburbs of our cities lie hundreds of millions of houses, with hundreds of millions of gardens. The reason gardens are so ubiquitous is that we psychologically require some part of our artificial environment to at least resemble nature. That is also why the paintings we hang on our walls often depict natural landscapes. While grass that is cut every week or two resembles nature, it is by no means natural. The hormones which suppress horizontal growth are in the tips of each blade of grass, which means that frequent cutting eventually creates a dense carpet which is impenetrable to anything but the grass.
To a bee, the difference between a well-cut lawn and a natural meadow is like the difference between a desert and a buffet. Global insect populations have been crippled in recent years by a combination of pesticides, herbicides, habitat loss and overactive lawnmowers. A 2017 study found that the number of flying insects in Germany has dropped by more than 75% in less than 30 years. Though you may think they’re creepy and unnecessary, insects serve a vital role in almost all ecosystems. Just like any other chain, if you break one link in a food chain, the whole thing becomes useless. The issue is not just the food supply of other animals, but also that some insects serve a critical function as pollinators. Three quarters of the world’s flowering plants and a third of all food crops depend on pollinators for their survival.
Plants really are the bedrock of all ecosystems. Animals have no way of converting the energy of the sun into energy that we can use to do things like move and breathe, so we rely on photosynthesising plants for all of our nutrients. Even if you eat a lot of meat, poultry and fish, it’s important to remember that those animals only survived their first day on earth because of the nutrition they got from plants. Whether it is corn-fed chicken or grass-fed beef, we owe everything we eat to plants. Without pollinators like bees, many plants are left with no way to reproduce and, thus, no way to survive.
If it is a choice between the two, however, electric mowers are the much greener choice. The emissions are more controlled and you do not need to use fossil fuels to transport the petrol all the way from a refinery to your back garden. In addition to this, the EPA estimate that 17 million gallons of petrol are spilled on lawns each year by Americans refuelling their lawnmowers. That is 6 million gallons more than was spilled in the infamous Exxon Valdez oil spill in 1989. Manual mowers which are powered by the elbow-grease of the user are both cheaper and better for the environment than either of the other kinds. If you are not able to push a manual mower for that long, solar-powered models are also available.
Lawn mowers are expensive. The fuel or electricity which powers them is expensive. On top of that, the actual process of cutting the grass requires time and effort and is widely considered to be a chore. A 2008 poll found that 58% of Americans surveyed said that they disliked cutting their grass. Ian Graber-Stiehl, in an article for Earther, claims that Americans spend between 47.8 and 82 billion dollars per year on lawncare and landscaping, compared to the 49.4 billion dollars they spend on foreign aid. Like smokers or alcoholics, we are paying through the nose to shoot ourselves in the foot. And for what? So that the neighbours don’t look down on us? My personal view is that if having long grass causes someone to lose respect for you, then that person’s respect is something you can do without.
For me, the important question to consider here is whether the benefits of cutting the grass outweigh the costs. I would argue that the answer to this question is a definitive no. The list of cons includes the killing of wildlife, contribution to climate change, high costs, noise pollution, air pollution and the fact that most of us hate doing it. The only real pro is that cut grass looks better, but even that is a matter of taste.
Personally, I think that a natural garden, with all its colour and movement, looks far more appealing than a still and monotonous carpet of green. It is important to point out that this is not an all-or-nothing situation. If you don’t want to abandon your mower altogether, you can still allow a neat patch of grass to grow long or mow a path to a small clearing where you can immerse yourself in the wild beauty that will surround you.
We need to change the perspective on this. We should not look down on people with long grass, quite the opposite! Those people are the ones who are helping their local environment by providing food and shelter for wildlife and cutting down on their carbon emissions in the process. In the age of anthropogenic climate change and mass extinction, the aesthetic appeal of our gardens needs to be lower on our list of priorities than helping animals to thrive.
We have brought the natural world to its knees in so many ways. The continued existence of every species on earth needs to be our top priority, not because they cannot take care of themselves, but because we are the ones who have endangered them. We have a responsibility to fix what we have broken and not only does leaving your grass to grow achieve that goal, it also saves you money and reduces greenhouse gas emissions. It is not often that you find a free way to help the environment, let alone one which will save you both money and effort. This is one of the rare win-win ways in which we can help our fellow inhabitants of earth get back on track.
Every minute, the equivalent of a truckload of plastic enters the sea. Since 2004, humans have produced more plastic than we did in the previous 50 years combined. As the global population rises, our need for cheap and sturdy materials rises with it. The problem with plastics is that they are too sturdy. Every piece of plastic ever produced still exists somewhere in the world. Once the plastic has finally disintegrated, that is by no means the end of the problem. Plastics in the ocean break down into tiny particles known as microplastics. Such particles are found throughout marine ecosystems; from the stomachs of fish, to the stomachs of the seabirds who eat them.
Microplastics are not only dangerous, but also extremely difficult to clean up since they are spread out by currents all across the sea. In order to be classified as a microplastic, a piece of plastic debris must be roughly the size of your little fingernail or smaller. There are over 320 million cubic miles of water in the world’s oceans. For a sense of scale, you could fit roughly 320 million cars into a single cubic mile. Scientists have estimated that there are up to 50 trillion pieces of microplastics in the oceans. Given these figures, to say that removing microplastics from the ocean is no easy task would be the understatement of the century.
The reason that high levels of plastic in the ocean are problematic is that plastics have serious detrimental effects on the health of almost all ocean life. Over 800 species of animals have so far been shown to be negatively affected by plastic pollution. Considering that number was closer to 600 in 2012, it is safe to assume that the figure will continue to rise dramatically in the coming years. What’s more, almost 20% of the animals shown to be affected by plastic pollution are already classified as endangered due to human activity. There are two major ways in which plastics can harm or kill marine life. First, they can be ingested. When marine animals ingest plastic, the pieces can remain in their stomachs for the rest of their lives. As the amount of plastic increases, the space remaining in the stomach decreases, causing the animal to starve. In addition to this, most plastics are toxic to animal life, causing conditions like cancer and birth defects. Second, marine animals can become entangled in the plastic. If this happens at a young age, the plastic can restrict the growth of the animal, causing them to become severely deformed. This is seen most often in sea turtles. The worst offenders when it comes to entanglement are pieces of discarded fishing gear.
The phenomenon of marine life being caught by gear that has been abandoned by fishermen is known as ‘ghost fishing‘. Nets, hooks, lines, and cages continue to catch and kill fish long after the fishermen have stopped using them. Roughly 30% of all fish that are caught by humans are caught in ghost fishing gear. When you consider the sheer scale of human fishing, this percentage is astonishingly high. Leaving plastic fishing gear in the ocean, plastic or otherwise, is both short-sighted and despicable. Fishing gear is specially designed to kill as much marine life as it can. When it is under the control of a fisherman, protected marine life like whales and sea turtles can be avoided or released. Even so, fishing of any sort is devastating to endangered species. When the gear is abandoned, however, there is no targeting of species, leading to indiscriminate destruction of marine habitats.
There have been a lot of stories in the news recently about how companies like McDonald’s and Starbucks are ditching plastic straws. While this is a step in the right direction, straws only account for roughly 1% of the plastic debris in the ocean. In order to make a real difference, the companies would have to stop using plastic straws, containers, bags, cups, lids and everything else. This is a perfect example of what’s known as corporate ‘greenwashing’. If the public perception of a company is that they are trying their best to reduce the environmental damage they are causing, less people will boycott the company’s products, leading to higher revenue. Because of this, companies make the calculated decision to sacrifice a small portion of their profits in order to further their public personas as stewards of the environment. This is not to say that small steps forward like those taken by McDonald’s and the like are not helpful. Carlsberg have recently announced that they are ditching the plastic rings connecting cans in favour of glue dots. This is a positive development, since these connector rings have been shown to strangle and stunt the development of marine life and seabirds.
Plastic is not distributed evenly throughout the ocean. There are 5 major places, known as gyres, where currents have forced plastics to accumulate into huge expanses of debris. The largest of these gyres is called the great pacific garbage patch (GPGP) and contains about 2 trillion pieces of plastic. That’s 250 pieces of plastic for every human on earth in just one place. The GPGP is around the size of Texas and weighs about the same as 500 jumbo jets. The accumulation of plastic in gyres like the GPGP makes it somewhat easier to clean up oceanic plastic, but it is still a monumental challenge.
When he was just 17, Dutch aerospace engineering student Boyan Slat devised a huge U-shaped machine to clean up the GPGP that he believes could clear 50% of the plastic in just 5 years. The device uses ocean currents to move with the plastic, but since it is largely above the surface, it moves faster than the plastic, gathering it as it goes. It was deployed in the gyre in September of last year but was immediately faced with a slew of setbacks. The device was not travelling fast enough, allowing some of the plastic to escape, then a 60-foot section of the machine broke off, meaning that it had to be brought back to shore for repairs. Another issue with the device is that it cannot collect microplastics. However, it is important to gather up as many of the large pieces of plastic as we can now, since they will become microplastics in the future which will be much more difficult to clean up. We are in full damage control mode.
Despite valiant attempts to reduce our plastic consumption and remove the plastic we have already dumped in the ocean, it is highly unlikely that this problem will be solved any time soon. If anything, it will get much much worse. Humans have a history of showing up at a new location and decimating the native wildlife populations. When we first arrived in Australia, huge animals roamed the land. These included a 2-and-a-half-ton wombat, a flightless bird twice the size of an ostrich, and a predatory marsupial the size of a tiger. Within a few thousand years of humans showing up, 23 of the 24 animals that weighed over 50 kilograms had become extinct. We have spread all over the planet now, leaving only a few havens in which animals may thrive. The new frontier of animal extinction is marine life. Plastic pollution, overfishing and ghost fishing have devastated marine life and seabirds already, and the rate of destruction is only going to increase. All we can hope for is that people wake up to the genocide we are committing under the waves in time to save at least some of the majestic creatures who call the sea their home.
Pando is the largest living thing on earth. Weighing 6,000,000 kilograms, it is about as heavy as a thousand African elephants or forty blue whales. When you enter Pando, you may hear a soothing sound like the beating of tiny wings. Pando is a grove of 47,000 quaking aspen trees, named for the distinct sound their leaves make in the wind. Every tree in the forest is genetically identical. This is because they are all parts of a single being, connected underground by a huge root system. We cannot be sure of Pando’s age, but based on its rate of expansion, coupled with a knowledge of historic climatic conditions, it could be up to 80,000 years old. If Pando is this old, it is not only the largest known organism on earth but also the oldest. In a painfully familiar twist, humans pose a serious threat to this gentle giant.
Pando’s name derives from the Latin for ‘I spread’ as Pando started life as one seed, then gradually spread itself out over an incredible 106 acres of Utah, an area equivalent to 1,700 tennis courts. Aspen spread through a process called vegetative reproduction. They send out roots underground which travel horizontally for as much as a hundred feet before sprouting into new trees. The roots then carry water and nutrients to the new sprout as needed. One reason why aspen clones like Pando can get so big is that aspen are remarkably quick to repopulate an area following a major destructive event like a forest fire. Aspen compete with conifers for light and nutrients, a competition they may well lose without the help of forest fires. Unfortunately for aspen, humans tend to put out fires wherever we can, leaving conifers to creep into the aspen’s territory. This is just one of the ways in which we are harming Pando.
For the last hundred years or so, humans have been hunting predators like wolves, bears and mountain lions in Utah and the surrounding area, leading to an increase in ungulate (hoofed mammal) populations. The main culprits are a species known as mule-deer, who eat young aspen trees before they have time to grow a thick bark with which to protect themselves. Not only does a decline in predator populations mean that fewer mule deer are being eaten, but it also means that they have become more likely to stick around and enjoy the good eating. With no predators to chase them away, the deer see no reason to move on and find a new feeding spot.
It does not help that the US forest service allows ranchers to graze their cattle on Pando for two weeks every year. Aerial photographs taken over the last fifty years show that Pando is in serious trouble. Given such data, it is extremely irresponsible for the forest service to allow any grazing at all. You may well be wondering at this point why I’m telling you all this. Pando is not like other organisms. While it is a single being, Pando is also a vast ecosystem which is home to a huge variety of animals from black bears to wild turkeys. By saving Pando, we are saving not only a biological marvel but also a forest and everything that lives within it.
A healthy aspen grove should have trees of all ages growing within it. As in a human community, it is far from ideal for the individual trees to all be the same age. If everyone in a town is over 80, there will be no youngsters to replace them when they’re gone, and the town will die with them. This is exactly what is happening to Pando’s trees. The director of the Western Aspen Alliance and Pando expert Paul Rogers has said that in many areas there are “no young or middle-aged trees at all” and that the trees that remain are “very elderly senior citizens”. Aspen trees can live anywhere from around 75-150 years old. Worryingly, the average age of trees in Pando is 130 years; if we are to save it, we are going to have to move very fast indeed.
So what can be done to save Pando? Paul Rogers recently conducted an experiment in which parts of Pando were fenced off to stop ungulates from getting in. The experiment showed very promising results, although, despite the fences being 8 feet tall, the deer were somehow able to jump over them in some places and damage the new shoots. Some have suggested that to save Pando, wolves need to be reintroduced into the ecosystem to kill the deer. The proximity of Pando to campsites and cottages makes this idea hard to sell. The evidence suggests that taller fences around larger sections of the grove and a ban on all grazing should allow new trees to flourish. Once a new generation of trees come up and live to maturity, Pando will be in a strong position to live on for years to come. However, it will also face the very real threat of global warming if we do not significantly reduce our emissions soon.
Pando’s downfall is emblematic of the large scale ecological and climatic devastation that humans have wrought on this planet. By altering certain variables, we may have sealed Pando’s fate without even knowing it was there. It is important that knock-on effects like these are understood so that we may avoid repeating the same mistakes. Pando is also a symbol of how, with a bit of elbow grease and a bit less greed, we can at least partially right many of the wrongs that we have done to the natural world. When you are responsible for a problem, it is your responsibility to fix it. We can save Pando. Maybe by joining together to preserve this one beautiful colossus, we can create a success story that can serve as a poster-child for conservation efforts around the globe.
Back in February of 2018, the European Food Safety Authority (EFSA) released an updated report on the harmful effects of certain pesticides on a variety of bees. Confirming conclusions made in their 2013 report, the EFSA found a wealth of evidence supporting the claim that the world’s most popular pesticide group, neonicotinoids (or neonics for short) are harmful to both honeybees and bumblebees.
In April, following the EFSA’s findings, the EU put into place a complete ban on the use of neonics outdoors, expanding on the partial ban imposed in 2013 which prevented neonic use on certain crops. The move, which should see all European neonic use confined to greenhouses by the end of the year, was welcomed with open arms by environmental groups like Friends of the Earth and the Task Force on Systemic Pesticides. This fight, however, is far from over.
Neonics are a relatively new kind of pesticide. The use of these ‘systemic’ pesticides only dates back about 20 years. According to the UK Pesticide Action Network, “Unlike contact pesticides, which remain on the surface of the treated foliage, systemics are taken up by the plant and transported to all the tissues”. This includes the pollen and nectar which bees collect to feed their colonies. Systemic pesticides have also been found to persist in soil, water, dust and even air long after the chemicals have been sprayed. An open letter written in April and signed by 242 esteemed scientists claimed that “the balance of evidence strongly suggests that these chemicals are harming beneficial insects and contributing to the current massive loss of global biodiversity”.
The use of toxic systemic pesticides, which has steadily grown in recent years, is not just problematic for bees. The WIA (Worldwide Integrated Assessment of the Impact of Systemic Pesticides on Biodiversity and Ecosystems (in case you’re wondering)) included a report on the impact of these pesticides on vertebrate populations. The report reviewed 150 studies and concluded that neonics were both directly and indirectly affecting terrestrial and aquatic vertebrate populations. Some birds, for example, are directly affected by ingesting seeds coated in toxic neonics. Fish, too, have been found to be vulnerable.
While the report found that the amount of chemicals in the air were non-toxic to vertebrates at present, neonics are causing sub-lethal effects like stunting growth and reproductive success. Global populations of insect-eating birds, for example, are faced with a marked decrease in the amount of prey available to them. This is an example of an indirect harm caused by neonics. This food chain effect is incredibly important to consider. Bees are the ecological backbone of a vast number of ecosystems. A study published in Science in september of 2019 shows evidence that neonics have directly harmful effects on birds also. As well as delaying migratory habits, the study found that birds dosed with the equivalent of one tenth of one imidacloprid-coated seed lost 6% of their total body weight within 6 hours of being dosed.
The knock-on effects from the decline in bee populations will increase in scope and scale until a worldwide ban on neonics and other systemic pesticides is firmly in place.This goal, however, is far from being achieved. A 2017 report published in Science found toxic neonics in 75% of the world’s honey. Another study conducted the same year in Germany found that three quarters of flying insects have disappeared in the last 20 years, a period which coincides quite neatly with the introduction of neonics.
Multinational companies like Bayer and Syngenta, which manufacture neonics like imidacloprid and clothianidin, will fight tooth and nail to prevent ecologically responsible policy from passing into law around the world. Back in 2013, when the partial ban was proposed, Syngenta went as far as to threaten legal action against individual members of the EFSA, whose job it was to carry out an unbiased scientific evaluation of Syngenta’s products. For these business giants, profit margins are, as usual, more important than preservation of biodiversity. We must be ready for their inevitable appeals.
That being said, in May of 2019, the Environmental Protection Agency (EPA) cancelled the registration of 12 neonics, allowing companies like Bayer and Syngenta to sell off existing stocks, but not to produce more of the toxic chemicals. Surprisingly, the cancellations were voluntarily requested by companies including both Bayer and Syngenta. It becomes less surprising, however, when one knows that they only did this as part of a settlement agreement with environmental groups. The 12 neonics which these companies sacrificed were simply cannon fodder. The EPA still has nothing to say about the other 47 types of neonics.
Ever since governing bodies and NGOs have started to ban neonics, the race has been on to find a suitable replacement. One prominent candidate, however, may not be as bee-safe as its manufacturers claim. Flupyradifurone (FPF), which was approved by the EU in 2015 and has been sold under the name ‘Sivanto’ ever since, has been marketed as a harmless alternative to neonics. It is true that higher concentrations of the chemical are required to cause harmful effects in bees when considered in isolation, but when combined with common fungicides FPF has also been shown to kill bees. FPF works in much the same way as neonics, leading some experts and NGOs to say that the chemicals are so similar that it is wrong to consider them separate entities. Surprise surprise, Sivanto is manufactured by Bayer.
The EU and others, like Canada, are setting the example for other governing bodies to follow. If this problem is not addressed soon, however, we will leave future generations with a planet far less diverse and bursting with life than the one we had when neonics were first concocted. Neonics aside, humans are already the cause of the most recent of earth’s six mass extinctions. It says something about a species when they can take their place on a brief list which includes both asteroid impacts and cataclysmic volcanic eruptions.
At this point, we are in full damage control mode. Conservationists are fighting not only against pharmaceutical giants which wield more power than it should be possible to wield, but also against the clock. The public, however, have proved that this is one issue with which they can affect real change. Alongside the EFSA’s report, a driving catalyst for the EU’s ban on neonics was a petition started on the campaign platform ‘Avaaz’. The petition has received a staggering 5 million signatures. It is clear that people around the world care much more about preserving the biodiversity of this planet than they do about Bayer’s profits.
The Avaaz petition is a reminder that there are more of us than there are of them and that we can in fact stand up to them. We all know that rich bullies want to destroy this planet to fill their pockets, but we must not let them get away with it. I urge you, if you see a petition or a fundraising event for this issue, to become as involved as you possibly can. This issue is, if you’ll pardon my language, extremely fucking important.
Whales are notoriously vocal animals. Indeed, the catalyst for the ‘Save the Whales’ campaign of the 1970s can be said to be the release of the album ‘Songs of the Humpback Whale’ recorded by bio-acoustician Roger Payne. This was the first time that the public was able to hear and appreciate the astonishing variety and beauty of the Humpback’s songs. This love affair with the whales came in the nick of time, since the humpback population had at that time fallen to a historic low. It is estimated that by the late 1960s, over 90% of humpbacks had been wiped out by human activity.
Since the early 1920s, a technique known as ‘reflection seismology’ has been used to locate reserves of natural resources such as oil, gas and salt. Reflection seismology operates on much the same principle as sonar. Sound waves are emitted which reflect off the sea floor and are then measured by an array of sensors. Using this technique, areas of the sea floor can be accurately mapped, and it is possible to determine whether natural resources lie beneath the rock.
Modern reflection seismology is carried out using huge arrays of seismic ‘airguns’. These airguns can produce sounds of up to 240 decibels, over twice the volume of a standard rock gig. What’s worse, this noise level is produced every 10 seconds, 24 hours a day. According to Oceana, a single survey ship may carry up to 96 airguns at a time.
Whales and dolphins use sound to communicate with each other and, in some cases, for the echolocation of prey. Although insufficient research has been conducted to ascertain the detrimental effects of seismic testing on whales, preliminary data shows that almost all cetaceans give seismic airguns a wide berth. Further, sightings of cetaceans fall significantly when seismic testing is being conducted in a given area. Even in the absence of solid data, mere common sense dictates that the levels of noise produced by seismic testing may well prove to seriously harm the hearing of cetaceans, as well as disrupting their feeding, mating and migratory habits. In any case, if reflection seismology is at all likely to damage already strained marine environments, it is imperative that we halt that practice before the damage is irreversible.
It is not just whales that are at risk. During periods of seismic testing, local fishermen have reported an increase in dead fish floating in the sea. Squid, crabs and fish eggs have also been shown to be harmed by seismic airguns. It seems, then, that as well as deafening and disorienting endangered whales, seismic testing is also harming their ecosystem and thus limiting the availability of their prey. One study found that the number of zooplankton – tiny creatures that are the backbone of marine ecosystems – fell by 64% within 1,219 meters of airgun activity. That is guaranteed to have huge knock-on effects not just for whales and dolphins, but for all ocean life.
On the 1st of February 2018, seismic airgun testing off the coast of Newcastle, Australia was approved by NOPSEMA. The tests, which will be carried out by Asset energy, are approved right up until the 31st of May, with the whale migration set to begin around the 1st of June. This has been met with serious resistance. Greenpeace Australia campaigner Nathaniel Pelle noted that “Whales and other endangered species do not adhere to the Gregorian calendar and do not know the difference between May 31 and June 1”. The fact that this must be noted at all speaks to the greed and short-sightedness of regulators and fossil fuel companies.
In December of 2018, the U.S. (under the command of Donald Trump) began extensive seismic surveys of the entire east coast. This happened despite vehement opposition from almost all U.S. environmental agencies and state governments. The area which the U.S. has begun to survey is the home and breeding grounds of the North Atlantic Right Whale, a species so endangered that there are less than 500 of them alive today.
A final and crucial point to consider is that even if seismic tests did not damage marine populations directly (which they certainly do), they are a gateway to offshore drilling, a practice which damages marine populations in a number of ways. First, there is a possibility of oil spills which, as we all know, can be cataclysmic events for marine ecosystems. Further, when the oil is successfully extracted, it will be burned as fuel, releasing carbon dioxide into the atmosphere and accelerating the already severe effects of climate change. Renewable energy sources such as wind, solar and wave energy are the planet’s last hope for any sort of meaningful recovery. One may consider it an added bonus, then, that these energy sources do not require that we seriously harm marine species while they attempt to recover from the immeasurable damage that humans have already inflicted upon them.
