Apples or oranges?

I watched a very scary programme last night on TV. I think it may have been a BBC programme at some point as it was that sort of style and the original presenter was British before they dubbed it. It was about global warming and what our planet will look like in 60 years time if we don't change our habits. A time when a lot of us reading this will still be alive. Particularly scary was the fact that the rain forests will be totally gone. The effects the temperature changes will have is amazing too. They will only rise by about 2 or 3 degrees on average, but this makes a huge difference to the crops that can be grown. Spain will basically have no areas that are suitable for agriculture, and the rice that Japan will be able to produce will be 15% lower than now, which coupled with a increasing population does not bode well. Now a lot of areas are apple producing, but by 2050 most of these will have changed to satsuma trees. And the number of nasty infection carrying bug that will spread across the world is just unbelievable. Certainly made me want to recycle!
