Growing plants - thank goodness for the CO2 output. Plants do better with more CO2. Their stomata shrink and that saves water, which is often a crucial factor for plants and especially so for agriculture where farmers have to buy water, or pay for it to be delivered to their crops. ucsdnews.ucsd.edu <“Even if a plant closes its pores a little in response to increasing atmospheric carbon dioxide, it would still have access to carbon dioxide,” said Schroeder. “On the other hand, less water would be escaping through the pores, so the response might help plants use water more efficiently. Each plant species shows a different carbon dioxide responsiveness, and understanding the underlying mechanisms may make it possible to engineer improved water use efficiency in some crop plants or trees that will be exposed to higher carbon dioxide levels in the future.” > Plants also produce more carbohydrate, which is good for farmers who don't need to pay so much for CO2 enrichment in their greenhouses if ambient CO2 is elevated. Further research needed ... so far, so good for the Greenhouse Effect being a good thing. Plants, not surprisingly, love it. Especially if they were having trouble getting enough to drink. Mqurice
