Animal agriculture is the leading cause of species extinction, ocean dead zones, water pollution, and habitat destruction [xix] [iv] animal agriculture contributes to species extinction in many ways. Problems in species extinction extinction refers to the loss of species or other taxonomic unit (eg, subspecies, genus, family, etc each is known as a taxon) occurring when there are no surviving individuals elsewhere the extinction of any species is an irreversible loss of part of the biological richness of the earth. Extinction, in biology, the dying out or termination of a speciesextinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers. Species extinction evolution is the interplay of the appearance of new life-forms and the disappearance of old ones the appearance of new life-forms depends upon the availability of diverse habitats, relative stability of climatic regimes, and processes that allow genetic and behavioral modification to, in effect, isolate new life-forms from a common ancestor.
Extinction is one of the major features of evolutiona species is extinct when no animal of the species are still alive all species become extinct sooner or later the end of a species may happen for many reasons it may be caused by habitat loss or by being overhunted, or by a major extinction eventan example of an animal that is now extinct is the dodo, from over-hunting. Habitat destruction is the process by which natural habitat is rendered incapable of supporting its native species in this process, the organisms that previously used the site are displaced or destroyed, reducing biodiversity [1. The destruction of biodiversity we are in the midst of a global biodiversity crisis because of the widespread ignorance of the value of biodiversity, we continue in our non-sustainable destruction of species and ecosystems, decreasing our quality of life and endangering the future of our children. Extinction of species (of plants, animals, microorganisms), a phenomenon that occurs during the process of development of living nature during the earth’s geological history extinction of organic forms takes place as a result of natural selection in the presence of essential changes in the external environment in those instances when organisms do not.
Poverty, consumption and land-use patterns contribute to the degradation of marine habitats and to the destruction of the species that rely on them to survive great barrier reef marine park, australia, is a network of fully protected areas within a larger protected area, designed to protect all habitats in the region. Destruction of the habitat of a particular wildlife species intentionally or unintentionally leads to extinction of species the habitat may be destroyed by deforestation, drainage, overgrazing, expanding agriculture, urban and suburban development, highway construction, dam building, etc. These and many other examples of catastrophic species decline have demonstrated that the continued destruction of local populations leads to species extinction biodiversity trends of georgia's more than 4,000 species of native or naturalized vascular plants and vertebrate animals.
The wwf says 75m hectares of threatened species habitat has been destroyed since the environment protection and biodiversity conservation act 1999 came into force photograph: auscape/uig via. For species that rely on sound to communicate or execute mating strategies, noise pollution presents a problem extensive studies on songbirds show how many species have adapted by adjusting various aspects of their song to overcome residual noise. Evidence of species loss in amazon caused by deforestation date: august 24, 2015 source: lancaster university summary: researchers studying plants, ants, birds, dung beetles and orchid bees in the. The rapid loss of species today is estimated by some experts to be between 100 and 1,000 times higher than the natural extinction rate, while others estimate rates as high as 1,000-11,000 times higher. Extinction definition is - the act of making extinct or causing to be extinguished how to use extinction in a sentence the process of becoming extinct the extinction of a species also: the condition or fact of being extinct 2: the process of eliminating or reducing a conditioned response by not reinforcing it.
Top five causes of species extinction we are losing many species of animals and plants every year at quite a staggering rate never before seen since records began. Conservation: conservation, study of the loss of earth’s biological diversity and the ways this loss can be prevented biological diversity, or biodiversity, is the variety of life either in a particular place or on the entire earth, including its ecosystems, species, populations, and genes. Extinction of species is influenced by island area (smalllarge) and immigration of new species influenced by isolation of sailed from others (nearfar) metapopulations set of local population lives, can be occupied or unoccupied. Extinction of a parent species where daughter species or subspecies are still extant is called pseudoextinction or phyletic extinction effectively, the old taxon vanishes, transformed ( anagenesis ) into a successor,  or split into more than one ( cladogenesis .
Deforestation is the permanent destruction of forests in order to make the land available for other uses an estimated 18 million acres (73 million hectares) of forest, which is roughly the size. In the cases where we can trace the extinction of a species through man, either wholly or in one limited district, we know that it becomes rarer and rarer, and is then lost: it would be difficult to point out any just distinction  between a species destroyed by man or by the increase of its natural enemies. The act or process of becoming extinct a coming to an end or dying out: the extinction of a species psychology the reduction or loss of a conditioned response as a result of the absence or withdrawal of reinforcement. One in 10 uk wildlife species faces extinction, major report shows state of nature reveals the destructive impact of intensive farming, urbanisation and climate change on plants, animals and habitats.
An endangered species is one whose numbers are so small that it is at risk of extinction a species is defined as endangered or threatened when it is suffers from these factors: damage to its habitat for recreational, or entertainment purposes disease or predation of the species and hazards to the continued life of the species. The international union for conservation of nature (iucn), in its red list of threatened species, assesses species’ extinction risk as least concern, near-threatened, three progressively escalating categories of threatened species (vulnerable, endangered, and critically endangered), and extinct. The loss of more than 99 percent of primary, virgin forests in haiti is triggering an ongoing mass extinction of reptiles, amphibians, and other species this deforestation is the main threat to.
