Nuclear harvest.

This video looks at the opinions of working farmers, vets and animal biologists who talk about what a nuclear war would mean to the farming community and ultimately to everyone else. One farmer alarmed at the lack of available information set up an organisation 'Farmers for a nuclear free future'. A nuclear winter would have devastating impact on plant life as the sun is blocked out by the dust and soot in the atmosphere which will cause a drop in temperature. It's clear that current farming practices which are the backdrop to the production will no longer be possible; survival may be impossible.
