Desertification is the process by which land dries up and eventually turns into desert.There are many causes such as over-population,climate change,over-cultivation,deforestation and over-grazing.Those causes are related to each other too.For example over-population means more farmland,more cattle to eat.Since the cattles need to eat more grassroots,they will lead to over-grazing.Nowadays,desertification is a big global problem,because it reduces the ability of land to support life,and affects wild species,domestic animals,agricultural crops and people.Desertification is especially a problem in Africa which is a poorer continent compare to others.When famines due to desertification struck across its regions,Africa looks for the aid of other countries Since now I know some of the causes of desertification,I should tell people to halt desertification and protect our Earth.
