chemistry Land is often transformed from a forest or other natural landscape, such as floodplains and wetlands, into a crop field or pasture. Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow, and then transported and deposited in other locations. Around the globe, soil erosion is happening at a faster rate than it can regenerate. Yes, climate change has already been mentioned as a cause of soil erosion but it is also an effect of soil erosion too. Insecticides and pesticides may destroy organisms which help in making the soil coherent thereby promoting erosion.

A drier soil is more easily eroded by the wind, as you can imagine through the imagery of dust storms in deserts and other dry regions. 2 How does erosion affect peoples lives? Soil erosion is a serious problem that has many effects on both the physical and human environment. Long-term effects of soil erosion include waterway clogging and siltation. Sedimentation also leads to the excessive growth of algae, as sunlight can get through the sediment. SUSTAINABLE TOURISM Reduced Organic and Fertile Matter. As the human population has expanded, more and more land has been cleared for agriculture and other pursuits that degrade the soil and make erosion more likely to occur. Because topsoil is so fertile, if it is removed, this can cause serious harm to farmer's crops or the ability to effectively work their land. ; Bartarya, S.K. (5).
