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 ...
t. e. Land degradation is a process in which the value of a biophysical or biochemical environment is affected by a combination of natural or human-induced processes acting upon the land. [ 1 ][ 2 ] It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable. [ 3 ] Natural hazards are excluded as a cause ...
Society portal. v. t. e. Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments [ 1 ] and to ecosystems, biodiversity, and natural resources [ 2 ] caused directly or indirectly by humans. Modifying the environment to fit the needs of society (as in the built environment) is causing ...
Ecology portal. v. t. e. Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. [ 1 ][ 2 ] Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. [ 3 ] Plastics ...

Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall warming trend, changes to precipitation patterns, and more extreme weather. As the climate changes it impacts the natural environment with effects such as more intense forest fires ...
The exploitation of natural resources describes using natural resources, often non-renewable or limited, for economic growth [1] or development. [2] Environmental degradation, human insecurity, and social conflict frequently accompany natural resource exploitation. The impacts of the depletion of natural resources include the decline of ...
Environmental toxicology is a multidisciplinary field of science concerned with the study of the harmful effects of various chemical, biological and physical agents on living organisms. [ 1 ][ 2 ] Ecotoxicology is a subdiscipline of environmental toxicology concerned with studying the harmful effects of toxicants at the population and ecosystem ...
