You don’t have to have taken chemistry to know that CO2 is what we breathe out and plants breathe in. I wish the American people would laugh these clowns out of office.

Plants respire in addition to photosynthesizing. Excessive plant growth in a pond can deplete the O2 supply dissolved in the water due to plant respiration, and cause a fish kill.
