A career in alternative energy would be pretty interesting, and could possibly some into play in my job, but it's not what I'm planning on. As for global warming, we can't really prove it either way. It's such a big deal because people need something to worry about and something to fight about. People in the government use it to get ahead all the time, saying that they're fighting global warming, when they're really doing nothing... yet they get all the votes.
Al Gore is always talking about how important it is... while he flies around in his private jet, polluting the Earth. I hate that guy... he thinks that he invented the internet...
All in all, nobody really knows as much about global warming as they say they do, and we can't prove it either way. In my opinion, yes, we should be protecting Earth, but global warming isn't as big a deal as it's made out to be, and is probably mostly natural.

You and I both know that you want to make hobos fight each other.
