Why do naturalists suggest that we plant more trees? Plants use CO2 but do not release any, thus maintaining a balance of CO2 in the atomsphere. Plants release CO2 through respiration and use it for photosynthesis, thus decreasing the amount of CO2 and maintaining its balance in the atmosphere. Plants do not use any CO2, thus maintaining low levels of CO2 and balancing its level in the atmosphere.
