Lately ,global warming is becoming a serious problem.Several factors contribute to it.First of all,a lot of greenhouse gas is produced by cars and factories; furthermore,the loss of forests is another cause of global warming.Global warming will cause some harmful effects.Firstly,some islands will disappear because of the rise of sea level.Secondly,extreme weather results from global warming.When temperature rises,the production of crops will decrease.Besides,some animals and plants will disappear,thus destroying the ecosystem.So we should protect the earth from greenhouse gases.We should plant trees and reduce the amount of carbon dioxide and other greenhouse gases.Hope our earth can
become better and better.
