A whole country of vegetarians—could it ever happen? It very well might, but not because of ethical or health concerns. In the event of a world food shortage, the British population would likely adopt a vegetarian diet, according to a new official assessment on the UK’s food security. The country is currently at risk because more crops are being grown for bio-fuel instead of food, the worldwide population is increasing, and climate change is causing extreme weather patterns. A worst-case scenario would have Britain shifting the cereals used to feed farmed animals into production for human consumption. Perhaps this latest example of how unsustainable a meat-based diet is will help Britons and citizens around the globe to realize how much more efficient a vegan diet can be.
