Heavy tilling of the soil destroys its capacity to hold moisture, dramatically disrupts the soil ecology, increases the risk of erosion of topsoil and runoff into waterways, reduces its overall fertility, and reduces its capacity to store carbon. These anthropogenic activities simply alter the natural process combined, thus, destroying the natural ecosystems. Therefore, the estimates in Tables 3 and 4 are not directly comparable. Denudation rates vary widely in India, particularly in the Himalayan belt. This often causes over-exploitation of the natural resources, and contributes to environmental erosion. On this regard, degradation means damage or reduction in quality of environmental features, primarily influenced by human activities.

The Love Canal incident was a major impetus for passage of the Superfund Act, a law imposing strict liability, that is responsibility that cannot be bargained away from injury and damages arising from exposure to the spilled toxic contents. While the World Commission on Environment and Development Brundtland 1987 highlighted sustainable development, land degradation was only then seen as a shadowy adversary in achieving long-term productive agriculture. But there are even more serious problems how land pollution affects the environment. In this paper, we outline the impacts of restoration on ecosystems and societies and clarify some of the main challenges and approaches to ecological restoration. Biological processes include reduction in total and biomass carbon, and decline in land biodiversity. Sustainable land use can help to reduce the impacts of agriculture and livestock, preventing soil degradation and erosion and the loss of valuable land to desertification.

Surface mining leads to degradation of land. Desertification and land degradation can contribute to local warming by reducing plant cover and increasing soil exposure, which changes the energy balance of an area. Soil Erosion: Soil erosion is a serious problem in hills, and arid semi-arid areas. Erosion: Loss of vegetative cover has made land more susceptible to erosion. A possibility is bringing religious leaders into the picture to help educate their followers.

Effects of land pollution on the environment Land pollution, whether it is a barren space where nothing can grow but a few weeds or a site that harbors garbage and debris, like old tires, gas cans and plastic bags is an aesthetic drain. Unless a clear distinction is made, there is a considerable chance of overlap and double accounting. The report of National Bureau of Soil Survey and Land use Planning 1994 described that 57 per cent of the total geographical area of the country is suffering from different kinds of degradation of which a dominant part 45 per cent is under water erosion and the rest 12 per cent is from wind, chemical and physical deterioration. Human induced activities are also responsible for landslides. Erosion and soil productivity in Africa. At the point when environments are wrecked or common assets are exhausted, the is considered to be corrupted and harmed.
