Deforestation increases the temperature and pollution level on earth. Plants absorb carbon dioxide from the atmosphere to perform photosynthesis. If plants are destroyed, the level of carbon dioxide in the atmosphere will increase. As a result, carbon dioxide will trap more radiation, thereby adding to global warming. Global warming refers to an average increase in earth’s temperature. An increase in earth’s temperature will disturb the entire natural water cycle. As a result, there will be a change in the rainfall pattern, which in turn could lead to drought or flood.
