Endangered Species

A species or organism that is either few in number or threatened by changes to the environment or parameters of predation could be left at risk of becoming extinct is considered an endangered species. There are many countries that have laws in place to offer a special level of protection to these species as well as protecting their habitats. Most laws forbid restricting, development of land, hunting, or development of preserves. There are only a small number of species that get listed officially and receive protection legally. There are a variety of species that become extinct or will potentially become extinct without ever receiving notice from the public. The biggest concern is the rate of speed that each species has headed into extinction over the past 150 years.

Many species have evolved and through the last several hundred million years have regularly become extinct since the time of the Industrial Revolution. This however does not have any precedent in history biologically. If the extinction rate continues to escalate, which is seemingly the case, it is possible that in the next decade the number of species could be in the millions. Many people relate to the endangerment of birdlife or large mammals, there are some ecological issues that threaten the stability of ecosystems on the whole if there are key species that could vanish within the food chain.

In controlled environments captive breeding of endangered or rare species comes with restricted settings. This occurs in conservation facilities, zoos, and wildlife preserves. A species can be saved from extinction so that its population is stabilized and doesn’t disappear.

For some time this is a technique that has worked in captive mating, but does attribute to the menagerie of Asian and European rulers. These captive breeding techniques are not easy to implement for migratory birds and other species that are mobile. When the captive breeding population isn’t large enough, inbreeding is likely to occur and a gene pool is reduced and immunity is reduced.

There are thousands of species all over the world that become extinct. Many of them are only realized after they are gone. This means that the variability biologically, diversity of genetics, and future generations of livelihood are lost. Species that are endangered are likely to become extinct in the near future. Within the past 300 years mankind has increased the rate of extinction.

Some animal and plant species face a daily hazard when it comes to surviving. The biggest threat they face is humans. Many consequences of human actions such as deforestation, poaching, hunting, and even ecological disasters can cause damage to habitats, breeding grounds, and the food chain.
