Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
In contrast, according to Scherr, GLASOD (Global Assessment of Human-Induced Soil Degradation, under the UN Environment Programme) estimated that 6 million hectares of agricultural land per year had been lost to soil degradation since the mid-1940s, and she noted that this magnitude is similar to earlier estimates by Dudal and by Rozanov et al ...
Persistent organic pollutants (POPs) - organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. pervious surface – one which can be penetrated by air and water. pesticide - means any substance or mixture of substances intended for preventing, destroying or controlling any pest ...
Ecocentrism (/ ˌ ɛ k oʊ ˈ s ɛ n t r ɪ z əm /; from Greek: οἶκος oikos, 'house' and κέντρον kentron, 'center') is a term used by environmental philosophers and ecologists to denote a nature-centered, as opposed to human-centered (i.e., anthropocentric), system of values.
Environmental degradation, human insecurity, and social conflict frequently accompany natural resource exploitation. The impacts of the depletion of natural resources include the decline of economic growth in local areas; however, the abundance of natural resources does not always correlate with a country's material prosperity.
Oasification is also a developing direction of environmental engineering. To help the oasification process, engineers aim to develop a thriving dense woody plant cover to redress the hydrological, edaphic and botanical degradation affecting a slope. This is done through appropriate soil preparation and the introduction of suitable plant species.
Water pollution is an environmental issue that affects many water bodies. This photograph shows foam on the New River as it enters the United States from Mexico. Environmental issues are disruptions in the usual function of ecosystems. [1] Further, these issues can be caused by humans (human impact on the environment) [2] or they can be natural ...
According to another definition, it is "a change from a baseline state beyond the point where an ecosystem has lost key defining features and functions, and is characterised by declining spatial extent, increased environmental degradation, decreases in, or loss of, key species, disruption of biotic processes, and ultimately loss of ecosystem ...
