global warming is happening. just watch the movie by al gore. we aren't the only ones feeling the effects. the polar bears are feeling it the worse right now. they live on ice, and now with all of the ice melting they have to swim even farther. many are drownding from these condidions. many cubs are also dieing because of the lack of food so the parents can't give them any. please help spread awarness about this serious issue so it can be stopped.
