Carbon cycles in nature can be balanced, so the concentration of CO2 in the atmosphere stays relatively constant. However, if the total amount of trees and other plants increased worldwide, CO2 levels in the atmosphere would decrease. Explain why.

During Northern Hemisphere spring and summer months, plants absorb a substantial amount of carbon dioxide through photosynthesis, thus removing it from the atmosphere and change the color to blue (low carbon dioxide concentrations).

I honestly don't know if this helps or not
