"Q: Wasn't agriculture developed as a response to
famine?
A: Agriculture is useless as a response to famine. You can no
more respond to famine by planting a crop than you can respond to falling out of
an airplane by knitting a parachute. But this really misses the point. To say
that agriculture was developed as a response to famine is like saying that
cigarette smoking was developed as a response to lung cancer. Agriculture
doesn't cure famine, it promotes famine--it creates the conditions in which
famines occur. Agriculture makes it possible for more people to live in an area
than that area can support--and that's exactly where famines occur. For example,
agriculture made it possible for many populations of Africa to outstrip their
homelands' resources--and that's why these populations are now starving."
