it makes possible earths ultraviolet - absorbing atmosphere.
it will prevent us from suffering any consequences from global warming.
its the reason why venus has so much more co₂ than earth does.

Explanation:

The carbon - dioxide cycle helps regulate the amount of CO₂ in the atmosphere. CO₂ is a greenhouse gas, and by regulating its concentration, the cycle helps keep Earth's temperatures moderate. The ozone layer makes Earth's ultraviolet - absorbing atmosphere possible, the CO₂ cycle can't prevent all consequences of global warming, and it has no relation to the CO₂ difference between Venus and Earth.

Answer:

It regulates the CO₂ concentration of our atmosphere, keeping temperatures moderate.
