I’ve converted to veganism to reduce my impacts on the living world
The world can cope with 7 or even 10 billion people. But only if we stop eating meat. Livestock farming is the most potent means by which we amplify our presence on the planet. It is the amount of land an animal-based diet needs that makes it so destructive.
An analysis by the farmer and scholar Simon Fairlie suggests that Britain could easily feed itself within its own borders. But while a diet containing a moderate amount of meat, dairy and eggs would require the use of 11m hectares of land (4m of which would be arable), a vegan diet would demand a total of just 3m. Not only do humans need no pasture, but we use grains and pulses more efficiently when we eat them ourselves, rather than feed them to cows and chickens.
This would enable 15m hectares of the land now used for farming in Britain to be set aside for nature.
You need the shit from the animals to grow the sodding grains and pulses. Assuming that you’re not going to use that nasty artificial fertiliser stuff.
