On April 5, 2017 Nature, the International Journal of Science published an article written by nine climate experts that proved more CO2 means more food because plants feed on CO2 and produce OXYGEN which benefits air breathing life. Human babies thrive on more oxygen. People breathe easier and live longer when the air has more oxygen in it.
Humans invented many useful devices that use fossil fuels to produce useful, life lengthening devices and those processes increase CO2 which helps plants that produce Oxygen which helps humans breathe better. It’s a natural symbiosis between plants and humans.
