soil and its conservation
the destruction of the soil leads to desertification. Its happens before a fire, a tree cut or in an over exploited agricultural land. In any of these cases the vegetation is eliminated. Therefore the soil isnt protected against erosion produced by rain. Te soil is eroded by water and the land cant supporte vegetal life in the future.
the demand of the water
fresh water is renewable and is in scare supply on our planet.
pollution and overexploitation of aquifers or wasterfuluse these resources are dangers due to its consumption in developed countries.
the ability of drinking water for people and animals doesent depend on the being dry or wet, but on its level of development. Countries in central afica dont have a sewerage system or a water distribution network.
the disponibility of water depends on the level of development more than on the climate.
