Question

What would happen if humans start photosynthesis?

Answer 1

Explanation:

There is a balance of oxygen and carbon dioxide because we take in oxygen and give out carbon dioxide which is taken by plants and in turn they release oxygen. If humans start photosynthesising, carbon dioxide becomes a limiting factor.

Answer 2

Answer:

If humans start photosynthesising, carbon dioxide becomes a limiting factor. Even if we get carbon dioxide from other animals, it is inadequate considering the huge population of humans and plants. Eventually we all will die due to competition.
