Top Ten Green Jobs.

Large scale GM* is the way to feed the most people. Large scale farming is more efficient, and GM is as well. With the same amount of space in total you get more food OR using less space you get the same amount of food. Not everything natural is good, not everything good is natural. Arbitrarily limiting yourself to only the natural would mean less efficient farming, which means less people fed, or more space is used for farms and more people have to farm.

*not the type where it's designed so that you only get one harvest out of it.
