If "greenhouse gases" are so destructive to our planet and our lives, why are greenhouse nurseries, where they create the greenhouse gas to grow the plants by pump CO2 into the closed greenhouse, not outlawed?  

I gave you 3 scientist that reject the claims being made by climate change activist, one of which started the idea of CC and taught it to his students one of which was Al Gore, who got hooked on that claim.  He totally rejects what he once believed.  Another I mentioned was the founder of the Weather Channel, and a third was the co-founder of Greenpeace who testified in Senate hearings on the issue claiming it is false science.  Tens of thousands of scientist agree with him.
