1) Back when CO2 was a dominant gas within the atmosphere, cyanobacteria evolved that utilized CO2 and sunlight to make food. They were the precursors for all modern plant life. And today, CO2 is a trace gas. Yes it is true that many species of plants can benefit from increased CO2 in the atmosophere. It is also true that too much of a good thing is a bad thing. And the research as borurne that out, since it can be shown that plants can readily increase their uptake of CO2 only up to a limit, beyond which it becomes detrimental to their growth. And that is because plants have adapted to the concentrations as they exist in the atmosphere, and can only adapt up to a point to ever increasing concentrations, and certainly NOT at the rate we are emitting it into the atmosphere.2) How Christian of you to say so.
