Are You Really an Environmentalist If You Still Consume Meat?

I have encountered various types of environmentalists with the aim of reducing their plastic waste, advocating for a greener community, and performing beach clean ups to minimise environmental damage. Many of these self- pronounced ‘environmentalists’, however, fail to address the critical issue of animal agriculture as a severe cause of climate change.

Last week, I posed a question on Instagram: “can you call yourself an environmentalist if you still consume meat?”, and although there were only two options available, I felt there was a diverse range of potential responses and reactions to the question posed. My personal take on that is: no, you are hardly an environmentalist if you still consume meat. However, this is my own opinion, and the aim of this post is not to belittle those who are actively trying to preserve the environment without going vegan or vegetarian. I am not flawless in my approach, but the purpose is to shed light on the complex issue of climate change that arises from daily habits that we often neglect. Equipped with the education I received from the Food’s future Summit and from my own personal research, I will attempt to explain why:

1. Catching our Feed

Firstly, we all know that there is an astounding amount of plastic lurking in the depths of our ocean. There are various initiatives people have taken to curtail the damage, but many are unaware that one of the most common items found underwater is not plastic straws, cigarette butts, plastic bags, or plastic rings, but rather, an abundance of fishing nets - a product of aquaculture.

In short, aquaculture refers to the farming of fish and other sea creatures to satisfy the diets of our population, but the often overlooked aspect of this practice is the overfishing. When fish farmers fish for their required species of marine life, their nets simultaneously capture everything they need plus more. This in turns results in an unnecessary load of animals put to death for no purpose other than convenience - causing a lack of substantial biological life to sustain into the future.

These fishing nets trap animals and prevent then from moving freely; they strangle the coral, which are significant contributors to biodiversity, and they enter the digestive systems of marine life. Additionally, the irreversible construction of plastic means that instead of decomposing over time, it only breaks down into smaller and smaller particles known as micro-plastics.

Not only do these micro-plastics negatively impact the state of our environment and marine life, they are shown to contaminate our food and even our water supply. Through a process known as bioaccumulation, the particles that are ingested by sea creatures end up in larger amounts at higher levels of the food chain (meaning us). This plastic infiltrates any source of ‘clean’ water available and is detrimental to the health of sea life, ourselves, and the environment.

Aside from avoiding single-use plastics, we can significantly reduce our environmental impact by eliminating the need for fishing nets in the ocean, and this can be easily done by decreasing the demand for seafood.

2. Feeding our Feed

Secondly, due to the high demand for beef and the level at which beef needs to be produced, cows are often placed under concentrated and industrial rearing environments which not only increase the harm posed to agriculture animals, but their diets are commonly altered from their natural grass-fed diets to that of grains such as corn and soy to accelerate growth.

Corn that is fed to cows are often grown in monocultures, meaning that an abundance of land is required to grow the single crop. In order to produce corn at great rates to feed the cattle, many nutrient fertilizers and pesticides are also required. These fertilizers can seep into lakes, rivers, and oceans, causing algae to grow and spread, and eventually depleting the water’s oxygen supply. At some oxygen depleted zones, many sea creatures are unable to survive. Additionally, some versions of corn that are genetically modified to eliminate pests contain toxins, and when parts of these plants wash into oceans or other environments, other insects are also affected - putting other species in the ecosystem at risk as well  (Bardroff, Jenna).  

Similar to corn, many herbicides are used to accelerate the production of soybeans. To make space for the cultivation of soybeans, many rainforests in the amazon have been destroyed. Not only does deforestation of the tropical rainforest increase atmospheric Carbon Dioxide (CO2) levels, but it also removes the trees that convert CO2 into oxygen. Thus, an abundance of soil carbon can also disappear as plants and dead organic matter are removed. Rainforests store most of their nutrients in living matter; therefore, the destruction of trees causes large amounts of carbon to be released into the atmosphere. In Brazil alone, over 473 million tons of carbon dioxide have been released to make space for soybean plantations.

Additionally, soybeans are commonly produced on land that is highly susceptible to soil erosion, easily exhausting the soil’s nutrients and value to the ecosystem. Plenty of water is also needed to grow soybeans, and approximately 530 gallons are required just for two pounds. (Bardroff, Jenna) Because of the vast amount of resources needed to raise cattle, approximately 27% of the world’s water ‘footprint’ can be attributed to the production of beef; the amount of water used to grow crops for animal feeds is a highly inefficient use of a precious resource, and it also reduces freshwater reserves ("Health & Environmental Implications of U.S. Meat Consumption & Production."). When all of this is added up, one quarter-pounder burger requires 660 gallons of water in total to produce, and it takes upwards of 3000 litres of water to produce one steak. To treat water and transport meat, the energy required is 35 times more than what you’ll get out of eating it.

3. Run-off from our Feed

The livestock sector contributes around 14.5% of global greenhouse gas emissions - higher than all forms of transport combined (Cowspiracy). It is estimated that cattle convert up to 10% of the food they eat into methane, and they emit around 100 million tonnes into the atmosphere every year (Nagle, Garrett, and Briony Cooke 32)

The problem arising from methane emissions is not a one-off occurrence. Under high pressures and cold temperatures, methane molecules are trapped in water molecules that create a chemical cage - a clathrate - around them. When temperatures rise as a result of climate change, these clathrates become unstable and melt into water and release the stored methane gas. These are commonly found in the deep ocean where water pressure is high, and as the climate changes, the methane deposits expand into gas. On average, a cubic meter of clathrate contains 164 cubic meters of methane gas. (Podbury, M. J).

As a result of climate change, more methane is leaked. This then turns into a positive feedback loop - a process that causes changes to amplify ("Feedback Loops.") - where more warming leads to more methane, and so on (Andersen, Claus). In response to global warming caused by CO2 emissions, the melted ice releases methane. This causes the oceans to rise, and the rising oceans generate more methane - which is conducive to more warming. This continues in an endless cycle of destruction; methane acts on both the atomic and geographical scale, and although its effects are not fully understood, it is clear that it is detrimental toward our environment (Podbury, M. J).   

Climate change is conducive to greater occurrences of extreme weather, and milder winters and extended summers enable tree-killing insects to thrive. With higher occurrences of drought, the defence systems of trees are also lowered, meaning that it is easier for them to die. With less trees, there is more carbon dioxide present in the atmosphere, resulting in a continuous cycle of damage toward the environment.

The changing climate also puts wildlife and marine habitats at risk. Oceans absorb some of the carbon dioxide that is released into the atmosphere and ingests 90% of the extra heat in the climate. The carbon dioxide makes the water more acidic and less hospitable for marine life. The acid dissolves the shells of sea creatures by affecting their normal calcium balance, and the heat strips coral of their color through a process known as coral bleaching. ("Effects of Climate Change.") Algae is what nourishes corals with their vibrant colours, and when algae is distressed from the heat, it detaches, leaving the coral malnourished and discolored. In turn, the many sea creatures that depend on coral are unable to survive - thus disrupting the entire ecosystem. ("Causes of Sea Level Rise: What the Science Tells Us (2013).")

Environmental Damage from Animal Agriculture

Environmental Damage from Animal Agriculture

Overall, the threat that industrial animal agriculture processes pose to our environment far outweigh the short-lasting pleasure derived from meat consumption (I haven’t even touched on the social, economic, and health aspects of it!). This industry contributes to more greenhouse gases than all sectors combined, and the most simple and effective way to reduce your carbon footprint and contribute to a sustainable future is to reduce your demand for animal products. The purpose of my Instagram page and my blog are to show you that it’s possible to do so - even in Hong Kong - and with these resources plus plenty more online, there’s hardly any excuse to confront this lifestyle change. :)

Zero Waste Street Food

On our second day in Taipei, we decided to be a bit more adventurous. We booked a car for the day and headed to the outskirts of town. 

Of all the places that we visited, the one with the most food was 九份. It somewhat resembles Stanley market, but on sale was more food and fewer clothing items. I was slightly overwhelmed by the sheer amount of food that was available, so I decided to take a walk around before settling on my first purchase. 

It was not the first vegan option I encountered, but it was the first one that stood out to me as something special. It had a fragile exterior but a heart of gold. It was a sweet potato bun.

The little bun was very sweet and dense, so I decided I would opt for something a little saltier next time. However, all of what I had in mind dissipated the moment I set my eyes on the glass shelf displaying a colourful selection of fresh mochi. There was mango, strawberry, matcha…anything you could imagine fitting inside a mochi, it was there. I ended up going for the mango and strawberry flavoured ones, because they seemed to be the most heavily advertised and they were the current fresh, seasonal fruits.

I was ecstatic to find a recycling facility for plastic bubble tea cups and covers behind the mochi stall, because it’s rather rare to find bins - let alone recycling bins - on the street markets of Taipei!

Once again, the mochi was also stuffed with a layer of dense, sweet, red bean-like filling. So this time, I followed through with my promise, and the next thing I ate was something salty. Salty and stinky.

It is not common that I eat street food in Hong Kong, so what excited me the most about this day was being able to use my own container for the first time. It was a painful sight to see nearly every individual around me using a disposable cup, bag, straw, bowl, etc, so I didn't want to further contribute to the waste that was being produced. At all the stalls I ended up visiting, the shop keepers were very open towards the idea of using my own container; they didn’t view it as a burden, but rather as a sign of promise. The container I used was from Japan Home Centre - it is extremely easy to carry around (it's even collapsible!) and is now on my list of travel essentials! I'd highly encourage you to bring your own container, especially while hunting for street food; it's a super simple way to keep your food clean, reduce your carbon footprint, and show off your inner eco-warrior!
