> the world cannot support 7 billion people in a hunter and gatherer lifestyle. Not to nitpick, but if all of our species reverted to hunter-gather, it would quickly reduce the population to a level that could be sustained. Agriculture allows humans to have far more children then they could support otherwise, for better and worse. I also disagree that we would 'all starve', for similar reasons. > we don't have enough farmland to grow enough food for 7 billion without modern farming techniques This is also probably not true. We do not go down that road because without modern farming techniques, we would need a far larger percentage of the population engaged directly in food production. This actually has many advantages over modern farming but it's a hard sell.
