Green
soylent Green. Charlton Heston, Fanstastic movie and a must watch! soon this movie will be a reality. Over population is already here.
The food supply takes massive amounts of land which are shrinking from Development and Nature.
could you Eat Soylent Green if you had to?
The sad part is there is so much bs going on with our food these days it's hard to know with any certainty what exactly you are consuming. I agree, that movie is amazing.
edit> In answer to OP, no. I'd prefer a step "backwards" in our food. Back to when we consumed whole, natural, unmolested foods.
