What should Al Gore do next?

Al Gore has done a great job in spreading the environment message. It seems he is trying to give a wake up call to all of us. What I admire most about him is he is trying to reach out to the general public as well as to the most skeptical Government in the world. In fact I recently bought the DVD of his movie "An Inconvenient Truth" although I have seen it in the theater.
As a next step, Al Gore should consider a Plant Based Life Style for himself.
Animal products are highly taxing to the environment. By reducing our cattle, we can have many more forests and stop hurting bio-diversity on a massive scale.
Al Gore, GO VEGAN.
