From Linda Edwards:

Re: Climate-induced food crisis seen by 2100 (Jan. 10): I see no reason why there needs to be a food crisis at all if people abandon monocultures and adopt permaculture/food forest approaches. If we grow food where we live and design systems with plenty of diversity we can adapt quickly and easily.

The problem is, of course, that giant multinational agricultural companies will not like that idea, and they plough money into political parties. Many of these corporations would rather see millions starve than lose their profits. We need to take responsibility for our own food production and start where we live.
