this is actually becoming something of a global problem at the moment, or so i read in the papers. the thing of it is that many nations are pushing the use of bio fuels made from certain crops in an attempt to combat global warming. farmers are finding it much more profitable to plant these crops than it is to plant food crops, so they're growing bio fuel crops instead of the normal stuff, which is creating a global food shortage that's hitting the developing world real hard.
every solution seems to throw up another problem huh?
