Ecosystem valuation is an economic process which assigns a value (either monetary, biophysical, or other) to an ecosystem and/or its ecosystem services.By quantifying, for example, the human welfare benefits of a forest to reduce flooding and erosion while sequestering carbon, providing habitat for endangered species, and absorbing harmful chemicals, such monetization ideally provides a tool ...
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
Endangered species by reason(s) they are (or were) threatened — the cause(s) for species being endangered in their native habitats.; This is primarily a sub-category for IUCN Red List species by the external threat(s) stated in IUCN reports for each listed species (hyperlinked under 'References' &/or 'External links' on most wikipedia articles when species are on IUCN Red List).
The illegal wildlife trade is the illegal trading of plants and wildlife. This illegal trading is worth an estimate of 7-23 billion [30] and an annual trade of around 100 million plants and animals. [31] In 2021 it was found that this trade has caused a 60% decline in species abundance, and 80% for endangered species. [31]
Philosophers have attached intrinsic value to different aspects of nature, whether this is individual organisms (biocentrism) or ecological wholes such as species or ecosystems (ecoholism). [ 9 ] More utilitarian schools of conservation have an anthropocentric outlook and seek a proper valuation of local and global impacts of human activity ...
The Hawaiian and Mediterranean monk seals are considered to be one of the most endangered marine mammals on the planet, according to the NOAA. [31] The last sighting of the Caribbean monk seal was in 1952, and it has now been confirmed extinct by the NOAA. [33] [34] The vaquita porpoise, discovered in 1958, has become the most endangered marine ...
Using species data from the Database on the Economics and Management of Endangered Species database and the period that the Endangered Species Act (ESA) has been in existence, 1970 to 1997, a table was created that suggests a positive relationship between human activity and species endangerment.
The Endangered Species Conservation Act of 1969 provided a template for the Endangered Species Act of 1973 by using the term "based on the best scientific and commercial data." This standard is used as a guideline to determine if a species is in danger of extinction.
