phosphorus which cause natural growths to run away, into the
environment - have had nothing to do with it.

Yes, but natural growths soak up the CO2, giving off Oxygen. It averages

blooms. Neither is any good for the environment.

Seems to me - feel free to correct me - that while photosynthesis does use
CO2, plants do in fact use oxygen part from that. The obvious experiment
