Greenhouse gases like carbon dioxide, methane, and nitrogen oxide trap heat and do not allow it to escape into space. As a result, the average temperature of the earth’s atmosphere is gradually increasing. This is called global warming. Deforestation leads to an increase in the amount of carbon dioxide in the air because the number of trees which consume carbon dioxide is reduced. Human activities, thus, contribute to the accumulation of carbon dioxide in the atmosphere. Global warming is a serious threat. This is also causing sea levels to rise in many coastal areas, and also resulting in wide-ranging effects on rainfall patterns, agriculture, forests, plants, and animals.
