CONSEQUENCES OF EROSION:
-Decrease of flora and fauna of the soil core in the cycles of matter and energy in ecosystems
-Serious imbalance in the ecosystem of the soil, by the proliferation ofspecies opurtunistas
-Progressive loss of fertility, which in most cases induce farmers to increase the quantities of fertilizer, entering a vicious cycle that ends with the deactivation of the land forcultivation
-Reduction of vegetation cover with disappearance of some species
-Reduction in humidity provided by the vegetation
-Formation of sand and gravel in the fertile plains

SOLUTIONS
Toprevent soil erosion must be given proper use and perform actions that do not degrade. In any case, it is best to always be covered with vegetation. Agricultural land is convenient to use crops thatare appropriate to the terrain, and the rest of the land is good repopulate with native species.

POSSIBLE SOLUTIONS
Since much of the problem of deforestation comes from logging by small farmerswho cultivate the land to survive, can not be solved if there are no global plans to help these countries to achieve a steady development without razing their natural resources.
Another problem is thepressure exerted by large timber companies. The development of less industrialized countries, would contribute to the need of foreign exchange is less and therefore would be more difficult to convincegovernments of these countries to cede the exploitation of its resources. It would also be needed tougher legislation against large speculations are given.
Reforestation projects can help efficientrestoration of forests that are in poor condition or have disappeared.
Of course, the recycling of most paper and cardboard being used would save raw materials, and therefore less destruction of thewood
Legislation and forest fire prevention and social awareness are other points that should be tackled to get save the forest, which, as mentioned above, is a major source of life.
