Whether due to a facetious New Year’s resolution, a new documentary that spooked you off meat, or a genuine concern for your health, many of us have tried a new diet. It’s normal to experiment with what we consume on a daily basis. However, in the midst of all these trends, the environmental impact of our choices is hardly discussed. Whether you’re a strict steak-lover or a die-hard kale enthusiast, for those who have the means, it’s time to consider the impact your food has before it hits the table.
The keto diet
The keto diet is among one of the most popular ‘trendy diets’ today. In essence, the keto diet is made up of 75 per cent fat, 20 per cent protein, and five per cent carbohydrates.
Since it involves a high level of protein proportionally, many followers choose to consume meat products as their method of choice. However, meat production can have a massive carbon footprint.
For example, the production of livestock such as cows, chickens, and pigs accounts for 70 per cent of all agricultural land usage, and creates 18 per cent of the greenhouse gases released into our atmosphere. Moreover, 43 kilograms of greenhouse gas emissions are released for every one kilogram of beef produced. The keto diet is not doing any favours in correlation to environmental impacts.
Vegan and vegetarian diets
According to a 2018 Gallop poll, five per cent of Americans identify as vegetarian. Contrary to the common perception that cutting meat out of your diet correlates to a positive impact on the environment, a strict vegetarian or vegan diet may also have its own shortcomings, though it can still be a much better alternative to an omnivorous diet.
For example, vegetarians in the US commonly replace the meat in their diets with dairy products. Dairy products, an adjacent production to livestock, have a massive carbon footprint, since dairy cows release copious amounts of methane into the atmosphere, as well as other greenhouse gases, according to the World Wildlife Fund.
Dairy production also uses high amounts of water in order to nourish cows, and process manure. Moreover, manure runoff can pollute water systems, which can lead to serious health problems for consumers.
Vegans, however, do not consume dairy; in fact, they avoid animal products altogether. In theory, this should remove any negative environmental impact. However, according to the US Library of Medicine, pesticides used in conventional agriculture, such as fruit and vegetable crops, leak into surface level water where it can also pollute soil, poison wildlife, and harm other nearby plant-life.
It’s absolutely admirable to take on a new diet in order to improve yourself —personal growth is important. However, the next time you follow the next trendy diet, consider how much our Earth loses, too. There is no one diet that can save the planet, but individual consumer choices do add up.
