global warming

i couldn't watch the video in the link because of adobe, and i tried to watch it on an iPad and it wouldn't play. ill just answer the question through what i know. i think the main concern is that we may loose some key animals during climate change. like polar bears, they seen to be a mascot for climate change, other fish is the water gets to cold or to warm. and when we loose the fish we loose the predator that eats that fish. so i think what people are most afraid of is loosing one animal and then starts a chain reaction that will soon end on us. maybe in chapel when the room is not in use turn off all lights, and  electronics. we could recycle like we are already but have more bins around campus. my carbon footprint was for me 12 and my house was 23.
