Clearing forests using fire contributes to the greenhouse effect primarily for the following reasons:
-
Release of Carbon Dioxide: When forests are burned, carbon stored in trees and vegetation is released into the atmosphere as carbon dioxide (CO2), a significant greenhouse gas.
-
Loss of Carbon Sequestration: Trees naturally absorb CO2 from the atmosphere during photosynthesis. By clearing forests, we reduce the number of trees available to sequester carbon in the future, which means less CO2 is being absorbed from the atmosphere.
Overall, both of these factors enhance the greenhouse effect, leading to increased global warming.
