The problem is shops that sell us the idea of never-ending supplies, even if it is vegan organic hummus.

Ya it's a great point and then how much gets wasted by Supermarkets throwing it out or people letting it go bad in their fridges? Meanwhile millions die from humger elsewhere. It's a mad world.

Today we overeat ourselves on meat from sick animals. And as you rightly said, all those diseases only came about in our modern era of fast food, sick animals, and herbicides/pesticides.

Ya, this is it exactly man. Maybe it's time to become a bit more self sufficient again?
