Desertification of Sahara and Gobi desert
Desertification of Sahara and Gobi desert The planet Earth has many ecological problems, from small ones to very severe; some of them are not caused by humans although the biggest part of the ecological problems is created by human activity. It seems very illogical that we destroy our mother Earth the planet which is one and only home to us. We pollute the air we breathe, the water we drink and what is more we destroy animal habitat and also our habitat, the earth on which we build our houses. Destruction of the soil by human activity leads to many severe problems from degradation of the soil from farming, trough destruction from heavy machines used in agriculture to the soil erosion itself. Soil erosion can cause many problems and has a very bad influence on a fertility of the soil; it also causes a very severe problem which is desertification. Desertification is a huge problem in the areas around the deserts it destroys the habitat of people and animals and creates a new group of refugees, so called environmental refugees. Desertification is a consequence of unwise usage of the land in semi- arid and arid areas, it is created manly by humans and we have to fight it because it destroys the land, habitat and cultures.
