An Inconvenient Truth

In class we watched the film "An Inconvenient Truth" by Al Gore. I was amazed at the amount of information we actually know about global warming. The film was entertaining as well as informative. Al Gore discussed some major problems with our environment such as the polar ice caps melting and the increasing number of dangerous storms that we are currently experiencing. One thing that I have always thought is that the Earth is just going through its normal heating and cooling phase. Gore showed a chart (pictured) that shows just how bad our warming spike has gotten. I am not stupid or ignorant, I do know that this is obviously caused by humans and the industrial/wasteful lives that we live. However, after the first ice age the earth warmed and melted most of the ice, and then a second ice age came and went. This seems to me live volatile conditions that are natural. I am not saying that the global warming issue isn't bad, I am just saying that I don't know if it will be the end of human life and the world. Nature is adaptive... isn't it?
Regardless, these environmental issues have caused me to question my apathy towards global warming. I believe it stems from the complete disregard for our environment by our political leaders. We desperately need a president that cares about the Earth if we expect everyone to get on board. If the leader of our country doesn't care, why should we... could it really be that important if they couldn't care less. Now obviously I know this is an important topic, I just mean that if environmentalists expect to actually change how America treats the environment, they are going to need to start with the political leaders.
