(WRI, p.50) When the carbon is in plants, it is released back into the atmosphere in a process called cellular respiration. If the trees and plants are cut down, the carbon cycle is not completed. The carbon will not be effectively removed from the air. Fifteen tons of carbon (in the form of carbon dioxide) occur in the air column above individually hectare (2.5...
