"You never know". But guess what - the apocalypse is not coming. It didn't come in the 20s, 30s, 40s...you get the picture. There's never an apocalypse coming. And even if there were - you probably won't live through it. And if you do...then the better question is why didn't you stop it in the first place?

Farming today has to be a large scale, highly studied and high-yielding enterprise. There's lots of room for improvement, but very little benefit to it on a microscopic scale (put seeds in ground, water, hope they grow).
