There is a ton of information out there... What I found is that melting glaciers are creating greater distance between ice floes. Hence, polar bears have to swim greater distances from piece to piece. They get tired and drown. In 2005, I think, there were more than 70 found dead from drowning. Additionally, with warming temperatures, polar bears are moving into habitats they didn't previously occupy, and leaving ones they did. People and polars don't mix too well. Another issue is the entire food chain itself. All aspects of the environment are changing... too little food for this leads to too little food for that leads to hungry polar bears. Like I said, there's a bunch of stuff out there - google! Good luck! I did a similar project in biology a couple years ago.
