286 FYI...CO2 amounts to 0.04% of the earth’s atmosphere and of that tiny percentage mankind’s contribution is about 3-4%. Any climate change or global warming is nothing to do with carbon emissions but everything to do with the sun’s cyclical radiation variation.

Plants use the same pores to breathe CO2 and release water vapor. With denser CO2, their pores can be smaller, they retain water better, and need less watering.
