Though there may be several factors that cause global warming, These contributions come from everyday human activities such as the use of oil, and burning other natural gases. One of the most popular ways to release harmful gases such as carbon dioxide in our atmosphere is the emission of these harmful gases from our cars, fossil fuel burning power plants and the like. These activities can also result in air pollution which can be another factor that would lead to global warming. Things like cars, power plants and the like are necessary for everyday living which is why it is hard for humans to disregard these necessities simply because of global warming. Deforestation is another cause of global warming; it is when trees and plants are cut down to make way for other purposes. Trees and plants play a vital role in using up carbon dioxide and giving off energy. Without these trees and plants, carbon dioxide will continue to be released in our atmosphere. Also, it affects the habitat and biodiversity of plants and animals.
