Extinction

He stopped having any kind or combination of types and reduce biodiversity. Moment you die is the last individual of some sort of moment of extinction, although it is usually the ability to reproduce has lost before the death of the last individual in this species.
He is also the disappearance of the object on the planet and the impossibility of his appearance again. Extinction of the species is not the survival of the type or group alive. The extinction occurs before the death of the last individual in this species. Where it may be the death of another member is able to multiply in the group or in other words stop this species ability to reproduce to ensure their durability.

Causes of extinction

Said to be among those reasons that led to the mass extinctions factors disastrous, as the theory of comets hit or environmental like Volcanoes or ice as the ice ages or for the change in the rate of oxygen, ocean salinity, or to global climate change. Although logical and reasonableness of these reasons, it not offer categorical assurances, they hypotheses circumstantial or speculative, although these reasons are uncertain or unknown to us, because it is not easy to kill or alive objects revivalist many widely only through total disaster and sweeping. Has swept the land extinction of a large 11 thousand years ago due to the continuation of the last ice age, who spent two-thirds of the districts in North America and the rest of the continents, and this ice age has not subsided after the poles. But there are types resisted this great patio, including the type of person who was of the survivors, and reached beyond the top of its ranks, appeared Homo sapiens and the evolution of modern human Journeyman and thinker. Humans have become extinct Getty because of the above reasons or due to the indiscriminate death or because of a genetic switch to another race or because of the loss of genetic information suddenly or for environmental reasons unexpected like Exposure to nuclear radiation or increased global warming due to the greenhouse.

And from causes of extinction :

Environmental pollution

Environmental pollution is another important factor cause of extinction. Toxic chemicals, especially chlorine compounds and materials, fertilizers and pesticides, such as DDT, are concentrated in food chains. The effect of these materials is greatest in species near the top of the food pyramid. Water pollution and rising water temperature is an important factor also has spent several species of fish in many of the citizen. Oil-water pollution also destroys birds, fish and mammals. The oil could cover the bottom of the ocean for many years. It is also known that acid rain resulting from excessive toxicity of air caused the death of neighborhoods in freshwater lakes and the destruction of vast tracts of forest land.

Some types of endangered animals

There are more than 800 species of animals threatened with extinction and extinction and there are associations relay is maintained and need material and moral support for success.
Of these animals:
Wild pig Assam there is only now in the Assam region of India, which is no small numbers and faces the courtyard Animal lemurs, who now lives from 30 animals on the island of Madagascar and not excise him in any other place in the world



Turtle woods, did not remain only 1000 turtle living in the slopes of the Andes in Colombia after accelerated deforestation and destruction of the environment in which they live.



Clay frog is found only on the island of Mallorca, it is usually the animal carrying the male fertilized eggs on its back until they hatch, and the causes of extinction diseases and abuse of the environment in which they live .


Young parrot Albrkit not leaving only 200 birds in the southwest of the island of Mauritius, and that because of the loss of its food shared by the island mice in his food and pay to starvation



Flat-tailed bats, creatures that caused civilization, tourism and human assault on the normal living environment which helped to near extinction, leaving him the only now only 100Giant Panda.
