Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste. The most common chemicals involved are ...
Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, and animals (including humans ). In accordance with these agents, erosion is sometimes divided into water ...
Nonpoint sources of pollution are the primary contributors to eutrophication, and their effects can be minimized through common agricultural practices. Reducing the amount of pollutants that reach a watershed can be achieved through the protection of its forest cover, reducing the amount of erosion leeching into a watershed.
Environmental impact of miningcan occur at local, regional, and global scales through direct and indirect miningpractices. Mining can cause erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface waterby chemicals emitted from mining processes. These processes also affect the atmosphere through carbon ...
The environmental impact of agriculture involves impacts on a variety of different factors: the soil, water, the air, animal and soil variety, people, plants, and the food itself. Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss ...
The Universal Soil Loss Equation (USLE) is a widely used mathematical model that describes soil erosion processes. [1]Erosion models play critical roles in soil and water resource conservation and nonpoint source pollution assessments, including: sediment load assessment and inventory, conservation planning and design for sediment control, and for the advancement of scientific understanding.
Deforestation is a primary contributor to climate change, [ 1][ 2] and climate change affects the health of forests. [ 3] Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [ 4][ 5] Greenhouse gases are emitted from ...
Ending an eight-year legal battle, chemical giant Monsanto has agreed to a $160-million settlement with Seattle for its part in polluting a river that runs through the heart of the city with ...
