Answer:
Fewer plants (especially big ones like trees) means less oxygen. But there is a balance. More carbon dioxide in the atmosphere makes plants grow bigger and lusher, so they fix more carbon and produce more oxygen. ... Plants are self-sustainable generating oxygen by photosynthesis and carbon dioxide by respiration.
