CO2 and evolution of plants (Introduction)

A beautifully constructed article combining knowledge of evolution, plant biochemistry and the importance of CO2 levels. The UN's IPCC scare tactics about CO2 is criminal and simply is a money-making scheme for third-world countries.-"The current levels of carbon dioxide in the earth's atmosphere, approaching 400 parts per million, are low by the standards of geological and plant evolutionary history. Levels were 3,000 ppm, or more, until the Paleogene period (beginning about 65 million years ago). For most plants, and for the animals and humans that use them, more carbon dioxide, far from being a "pollutant" in need of reduction, would be a benefit. This is already widely recognized by operators of commercial greenhouses, who artificially increase the carbon dioxide levels to 1,000 ppm or more to improve the growth and quality of their plants."-http://online.wsj.com/article/SB10001424127887323528404578452483656067190.html?KEYWORDS=In+Defense+of+Carbon+dioxide
