Dear Mr. Holyfield, Thank you for changing your nickname from the "Real Deal" to the "Mean Green Fighting Machine". It is heartening to hear that you are going to fight global warming with the same passion that your fought Tyson, Bowe and Foreman. It is even better to hear that you are installing a 40 acre solar farm and an organic garden on your estate in Atlanta. So why are you, the nearly 47 year old four time heavyweight champion of the world, fighting global warming now?

"I'm pretty much going to do all I can to fight against global warming. I'll see what I can do to help and try to help other people who want to do the same thing... A mission as big as this needs someone who is recognized through the whole world," Holyfield said. "We as a people have to come together to save this planet."

You have to hand it to the man. He is right. As the G-20 discuss emissions reductions and with Copenhagen rapidly approaching, the world is about to engage in what we hope to be the defining battle to save our climate. Lean green fighting machines on one side, big polluters on the other - who is going to come out victorious? As you prepare for another comeback to the boxing ring, please consider this - if you really want to fight global warming, go to Copenhagen! We could use you there, looming large over the environmentalist and bureaucrats. Your presence alone will get results. And I would take my chances against anyone in Copenhagen over whomever your next opponent is. Do you want to fight global warming now? Click here give your carbon emissions an uppercut to the jaw!
