Why the nitrogenase enzymes catalyzes the nitrogen fixation reaction only in microanaerobic or anaerobic conditions?

#Environmental Science

O2 form ROS (reactive oxygen species) that inhibits the enzyme nitrogenase
Oxygen, being a strong electron acceptor, can damage these sites and irreversibly inactivate nitrogenase, so nitrogen must be fixed under anaerobic conditions
Because lack a PSI, the oxygen-producing photosystem of chloroplasts, so they do not generate oxygen
nitrogenase enzymes only active in anaerobic environment and inhibit in the aerobic environment due to O2
