No way to undo it i guess, but we can prevent it from being occoured in future. Recently, scientists of the Harvard University discovered that one of the five ice-beds of the North Pole has been disintegrated drastically within past one year. This fact was never noticed until last week of November 2006. It has also been noticed that this big ice-bed is now floating on the North Sea. This floated ice-bed can now start approaching down towards the north boundary of Canada. Scientists are trying to keep an eye on the movement of this ice-bed. Satellites are helping in this regard by sending continuous pictures and data of this ice-bed. The most worried part of this incident, apart from the Global Warming, is that if by any chance this ice object reaches near to the border of Canada, it may create a great problem for the ships which are regularly traveling near the border of Canada. There is a good article in AC. Just read that. You will understand we have something to do to prevent Global Warming. http://www.associatedcontent.com/article/156681/how_to_prevent_global_warming.html

I don't think there is anyway to undo the damage that we already did to the earth for so long now but I believe that the most we can do is to sort of ebb our usage of bad chemicals and maybe slow down global warming. Truth is, there are always people who can't get off their car to take a walk or use a bike, and there are always going to be factories, so like I said, it's not going to happen. Unless, of course, somehow everyone in the world (I mean EVERYONE) decides to just stop driving and using harmful stuff that emits harmful substances. Because I've actually studied global warming really in depth a few years ago, it is going to cause more than you said it will. It won't necessarily make the fertile areas unfertile but it will cause a lot of problems and chain effects that will eventually affect the whole world. Because global warming warms up the ocean as well, the ocean will expand due to thermal expansion. There will be, as a result, hurricanes and floods and islands will be "sunk" and stuff like that. Not only that, because of the warm weather, the polar ice caps will melt. With the ice cold polar caps melting into the ocean around the poles, the warm currents will be stopped. The warm currents are the ones that bring warmth to northern countries like European countries and Canada. When the warm currents stop up there, the currents will stop all over the world, causing another ice age. If you need more information about that, watched the Day After Tomorrow.
