He was not a founding member of Greenpeace, although he was an early draft into their number. The groups origins were in 1970, when the actual founding members were looking into protesting against nuclear testing. Moore got in on the action in 1971.

Amazing that no one seems willing to address the science of this article....
Explain how CO2 isn't good for the rest of the world.
Add in we've had period of far higher temperatures fairly recently and without the CO2 emissions we enjoy today.
If, in fact the CO2 is beneficial to the plant-life-FOOD-that increase in growth rates would absorb even more of the CO2.
Great all you need to do is plant billions of trees and stop deforestation because obviously there is too much C02 for them to keep up or the oceans and lakes wouldn't be turning acidic.
Don't forget you need to cut down mature forests and bury them because mature forests are carbon Neutral and if you don't bury them then a large portion of them get burned returning that same C02 into the atmosphere.

What? CO2 causes 'acidic lakes'? Your joking of course. Neither carbon nor oxygen converts to acid. The sulfuric acid that was occurring years...not decades ago was cause by coal burning and the diesel emissions. Both have been addressed and those lakes have recovered from my understanding anyways.
When carbon dioxide (CO2) is absorbed by seawater, chemical reactions occur that reduce seawater pH, carbonate ion concentration, and saturation states of biologically important calcium carbonate minerals. These chemical reactions are termed "ocean acidification" or "OA" for short. Calcium carbonate minerals are the building blocks for the skeletons and shells of many marine organisms. In areas where most life now congregates in the ocean, the seawater is supersaturated with respect to calcium carbonate minerals. This means there are abundant building blocks for calcifying organisms to build their skeletons and shells. However, continued ocean acidification is causing many parts of the ocean to become undersaturated with these minerals, which is likely to affect the ability of some organisms to produce and maintain their shells.
Since the beginning of the Industrial Revolution, the pH of surface ocean waters has fallen by 0.1 pH units. Since the pH scale, like the Richter scale, is logarithmic, this change represents approximately a 30 percent increase in acidity. Future predictions indicate that the oceans will continue to absorb carbon dioxide and become even more acidic. Estimates of future carbon dioxide levels, based on business as usual emission scenarios, indicate that by the end of this century the surface waters of the ocean could be nearly 150 percent more acidic, resulting in a pH that the oceans haven’t experienced for more than 20 million years.
