The eruption of one St Helen does more to effect global warming that all the damage done by man in his life time on earth.
There is a natural cylce of life for this planet as there is for any other one. If you believe that dinoaurs roamed the earth and that a glaciers covered what is now Canada and northern US you have to wonder why and where they went. What caused the Ice Age?
Was it the cycle of global warming that occurs brought on by the eruption of many volcanos causing just the effect that Ifferd states or was it casued by a meteor strikeing the earth creating a cloud from impact and fires? The cloud of ash from either will do just what Iffred describes.
We as a nation being as productive as we are do just as much as europe and other nations to slow the process. Since we aremore active, more productive we do pollute more than 3rd world nations but in different ways. I guess it is just a matter of how you want to see the issue of life and death on the planet.
I want one of these dooms day freaks to give me a time table on when global warming will causethe death of the planet. Then I want them totell me that we will not have developed alternative energy resources to forestall the horrific even within that time frame.
Think how far we have come in the last 100 years. Think how far we will advance using our resources in the next 30 years.
Or was it cause by the very large SUV that those dinoaurs drove because of their size? (Thats my bet, those dam SUV)
