• BS. Trees absorb CO2 and produce oxygen. In fact, there are no other sources of oxygen other than that produced by plants, which is why it is an unequivocal indicator of life on other planets. Oxygen is a very reactive element that is used up quickly, combining with other elements, if it is not replaced continuously, not possible by inorganic or geological processes. Refusing reforestation because it serves as an excuse to pollute more is absolute idiocy, an ad hominem fallacy. What is needed is to kick out the fossil energy lobbies from politics and “climate summits”, because they are the cause, not reforestation.
