As I learned while sitting at the metaphorical feet of the world’s leading revolutionary ecologists and food rights advocates, the only way for humanity to survive in any meaningfully sustainable way is for us to live entirely within our local food systems, eating the plants and animals that naturally live on our immediate landbase. And this most definitely does not include millions of acres of grains, the cultivation of which is amenable to only very small parts of the globe. To produce the vegan foods that I used to consider so cruelty-free; modern, industrialized agriculture forces land to grow crops that are alien and unnatural to it, robs the planet of its resources, destroys whole eco-systems, wipes out entire species of plants and animals, and creates a chaos of death and destruction as more and more wild land is needed to replace the devastated cropland.
