The soil erosion is a primary environment problem. It latter has effects that fall into the category of secondary environmental issues. The erosion of the soil is a very serious environmental issue, as it is the prime natural resources that enables the growth of plants, thus food for the living organisms, including the humans. Also, with high rates of erosion, the process of desertification significantly increases, as the soil is stripped of its top layers. The sediments that have been stripped of the soil can cause pollution of the air, though the stronger winds and storms that carry them, or with sediments getting to the water bodies and making them all murky, muddy.
