GWB & the Environment

Why is Bush trying to help the environment now? In the "Bush to Protect Three Areas In Pacific" article, talks about Bush's decision,saving three areas in the Pacific Ocean, he made this decision just two weeks before he leaves the office. Why didnt he thought about it when he had more time to do it. I think that what he is doing is really good by attempting to save some areas in the pacific ocean. Although I think he is doing it do look good before leaving the office. In the 'Bush's seven deadly environmental sins' article talks about how Bush comitted seven sins during his position as the president. It also talks about how Obama is planning to fix all of Bush's mistakes that he made by "trying to make the enviroment a better place".
