The digestive process of farmed animals, particularly cows, causes emissions of methane, a greenhouse gas.
Producing meat and dairy not only takes up land for animals to be reared on, but uses massive amounts of land growing crops to feed to animals. This unnecessary land usage causes deforestation, reducing the amount of trees and increasing the amount of CO2 in the atmosphere. This land usage can also cause drylands to …
Livestock are given antibiotics to treat sick animals and to prevent illness in healthy animals. This overuse of antibiotics leads to antibiotic resistance in bacteria, creating microbial diseases which are resistant to treatment with antibiotics, known as “superbugs”.
Animal-based agriculture is an enormous drain on the planet’s water supplies. Huge quantities of water are used up producing feed for animals rather than food that could feed humans directly.
When animal waste is broken down, it produces nitrous oxide, a greenhouse gas. Nitrous oxide is 300 times more potent than CO2 in its warming effect.
Farming induced deforestation destroys the habitats of countless species across multiple continents. Palm oil, an ingredient in animal feeds, is grown in plantations which destroy the homes of orangutans, elephants, and other jungle animals, placing these species at risk of extinction. Marine life is also affected, as fish farms leak waste into coastal habitats which …
Going vegan can reduce your individual carbon footprint by up to 73%. A global change to veganism could reduce greenhouse gas emissions by two thirds, and save up to 8 million lives by 2050.
