Many people have bought books by Yuval Noah Harari, including his bestseller 'Sapiens'.His piece in the Guardian explores the impact of industrialised farming on the world. It provides some eye-opening statistics on the scale of food production that is necessary to feed the world. Scale that down just to the UK, or any large city, and you can imagine the resources that go into ensuring that our stomachs stay full.
Something to think about the next time you push a trolley round your local supermarket...
Update
Is Veganism the answer? Perhaps not according to this item from the Guardian today.
