Another day, another " is doing something tree-huggy" bit of news, with the actor once again taking to his active Twitter account to encourage his fans to support him. His latest cause? Opposing the controversial Keystone XL Pipeline, which has drawn major concern from environmentalists due to the fact it will mess up Alaska's delicate ecosystem for quite some time.
He's recently also tweeted about the importance of recycling, and conservation of the Arctic polar caps. If he could also tweet about paying off my student loans, that would be great.
