   Pollution

   Water pollution causes approximately 14,000 deaths per day, mostly due to contamination of drinking water by untreated sewage in developing countries. ... These would have included the demise of a population locally or ultimately, species extinction.
2. close

   Extinction

   There are a variety of causes that can contribute directly or indirectly to the extinction of a species or group of species. ... Genetic pollution
3. close

   Extinction event

   Causes ... While the role of humans is unclear in the longer-term extinction pattern, it is clear that factors such as deforestation, habitat destruction, hunting, the introduction of non-native species, pollution and climate change have reduced biodiversity profoundly.
4. close

   Global dimming

   Increased pollution causes more particulates and thereby creates clouds consisting of a greater number of smaller droplets (that is, the same amount of water is spread over more droplets). ...

   Pearl

   Since the time of peak production in 1971, when Biwa pearl farmers produced six tons of cultured pearls, pollution has caused the virtual extinction of the industry.
6. close

   Biodiversity

   Even though biodiversity declines from the equator to the poles in terrestrial ecoregions, this is still a hypothesis to be tested in aquatic ecosystems and especially marine ecosystems where causes of this phenomenon are unclear . ... Purebred naturally evolved region specific wild species can be threatened with extinction through the process of genetic pollution i.e. uncontrolled hybridization, introgression and genetic swamping which leads to homogenization or replacement of local genotypes as a result of either a numerical and/or fitness advantage of introduced plant or animal.
7. close

   Human extinction

   Catastrophic climate change as a result of global warming or the effects of extensive deforestation and pollution. ... Perception of human extinction risk
8. close

   Noise pollution

   An impact of noise on animal life is the reduction of usable habitat that noisy areas may cause, which in the case of endangered species may be part of the path to extinction. ... Pollution

   Quaternary extinction event

   Therefore this theory holds Pleistocene humans responsible for the megafaunal extinction. ... Extinctions in Near Time: Causes, Contexts, and Consequences.

    Wild fisheries

    The main causes of currents are: solar heating, winds and gravity. ... Reduction of habitat, hunting and fishing of some species to extinction or near extinction, and and pollution tend to tip the balance of biodiversity.
