Question

what happens when the amount of oxygen is doubled on earth​

Answer 1

Explanation:

In presence of double the amount of oxygen, combustion and respiration would speed up, but photosynthesis will slow down big time as it depends on Cardon-di-oxide. There won't be a single green plant on earth and non-green plants like mushroom and mosses will take over the entire planet.

Answer 2

Answer:

Doubling the Earth's oxygen levels would mean having even more oxygen in our atmosphere than back then. ... With a higher oxygen level, you'd notice you that have much more energy. The human endurance records of today would be quickly shattered after everyone gets more oxygen in them. You'd also be more alert.
