The amount of carbon dioxide has undoubtedly increased in the last hundred years-thanks to the activities of man. The amazing thing, about this problem, is that the content of carbon dioxide in the atmosphere is just 0.0391% (as of 10/2012). This amazingly small amount of carbon dioxide in the air is enough to cause the acidification of todays oceans. This small acidification of the oceans is still such that it is causing havoc on thousands of coral colonies by bleaching them and keeping millions of plankton from forming complete skeletons. This small amount of carbon dioxide is still large enough to have a major impact on life in the oceans today. Life is impacted despite being self-contained organisms with membranes; impacted despite having mechanisms to maintain their internal pH; impacted despite there being a fully oxygenated atmosphere. Would it not then stand to reason, that a larger amount of carbon dioxide in the atmosphere on the prebiotic Earth would have had a mu
