Do you think climate change is threatening our food supply?

It all has to do with gene pool diversity. As the world's climate changes, the gene pool diversity of crops will inevitably get smaller as more and more species disappear. When you've only got a minimal number of surviving crops to work with genetically, the possibilities to adapt them genetically are greatly reduced.

"...while securing the world’s food supply will require much work beyond crop diversity conservation – such as further advances in crop science, building efficient markets, and reducing the waste of food – none of this can be effective if the genetic base of our food supply is lost." In such case it is good to have a back-up; crops hold in a vault from before they went extinct and which can be genetically modified so they adapt better to a changed environment. "Historically, half of the increase in crop yields has come from conventional genetic improvement: Breeders identify useful genes in existing varieties of food plants and recombine them to develop new varieties that are more productive, more nutritious and more resistant to stresses – like higher temperatures or less water."

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
