Answer: CO2 in the atmosphere

Explanation:

During photosynthesis, plants removes carbon dioxide in large amount from the atmosphere and then utilize the carbon atoms to build up organic molecules.

Thus, this removal of CO2 from the atmosphere provide a natural solution to prevent the gas accumulation in the atmosphere, which is often generated by human activities and natural causes.
