What are three ways to help keep the carbon dioxide-oxygen cycle in balance?

Question

Serious answers only please.

Answer 1

There's only one way, and that's:
1. Refrain from putting excess carbon dixoide into the atmosphere; i.e. refrain from burning large amounts of fossil fuels.

If you want to add to that, you can:
2. Refrain from deforesting forested areas, especially tropical rain forests.

If you want to be constructive:
3. Plant more vegetation in areas in which it can grow. This can include reforesting. Sensible forestry practices, planting and harvesting, can "fix" carbon as wood.

Answer 2

If everyone stopped breathing, it would reduce the use of oxygen AND also reduce the production of CO2.

Answer 3

Dont breathe too much.
