Global Warming could spark U.S. and Canada disputes

I got some really terrifying news from Yahoo. It's fearful to think of the oncoming danger due to climatic changes and global warming, that is affecting both plant and animal life all over the world. What's more dramatic is the possible turn of events that might lead to squabbles in North America over water reserves.

It is as if our own planet is being destroyed before our very own eyes by elements and factors that were originally meant to make life more comfortable. Somewhat ironical is the current trend of exploration by scientists-looking for possible life sustaining planets. What's wrong with trying to save our own?
