Every body on this earth should do something for the protection of wildlife,Human activities are destroying the forests and number species on the earth,forests and wildlife are decreasing rapidly,the main reason of this thing is increasing in population,people are cutting trees and destroying forests and killing animals for there self s,if we are doing like this there will be nothing on this earth except human being,we will be alone on this earth after some years if we do like this,so each and every body do some thing as you can......

What's being done to help?
Some private and governmental efforts have been mobilised to save declining species. One immediate approach is to protect a species by legislation. Countries all over the world make laws to ensure that there are mechanisms for the conservation of ecosystems on which endangered species depend. In 1972 the Environmental Protection Agency was established in America. Australia has also established agencies through Acts of Parliament (The Endangered Species Act 1992) and the Wildlife Protection Authorityto discouraged the exploitation of endangered species within Australia. It also supports other countries efforts by banning the importation and trade of any product made from such species. Countries have various agreements with other nations_for example, USA with Canada and Mexico for the legal protection of migratory birds.
International efforts center on the Convention on International Trade in Endangered Species of Wild Fauna and Flora, ratified by 51 nations. Its purpose is to restrict exploitation of wildlife and plants by regulating and restricting trade in species. The effectiveness of such laws in various countries, however, depends on enforcement and support by people and the courts. Because of a lack of law enforcement, the willingness of some segments of society to trade in endangered species, and the activities of poachers and dealers who supply the trade, the future of many species is in doubt in spite of legal protection. Australian species of wildlife are in great demand because they are unique, especially bird-life. Recently, in Australia, penalties for trafficking in protected and species have been increased. The court system is committed to strict application of the laws.

Hunting for food and other reasons
Since the 1600s, commercial exploitation of animals for food and other products has caused many species to become extinct or endangered. For examplethe slaughter of great whales for oil and meatthe African rhinoceros, killed for its horn, the great auk became extinct in the 19th century because of over-hunting the Carolina parakeet perished as a species because of a combination of over-hunting and habitat destruction. Introduced diseases, parasites, and predators against which native flora and fauna have no defenses have also exterminated or greatly reduced some species. The accidental introduction of a blight, for example, eliminated the chestnut tree from North American hardwood forests. Predator and pest control also have adverse effects. Excessive control of prairie dogs, for example, has nearly eliminated one of their natural predators, the black-footed ferret. In Australia the introduction of rabbits and cats has caused the destruction of much of the wildlife. In Queensland the Great Barrier Reef is under serious threat by the Crown of Thorns starfish.
Why are there endangered species ?
Habitat DestructionSpecies become extinct or endangered for a number of reasons, but the primary cause is the destruction of habitat. Man has seriously reduced available habitats byDrainage of wetlands conversion of shrub lands to grazing lands cutting and clearing of forests (especially in the Tropics, where the rain forests will be gone by AD 2000 if destruction continues at its present rate) urbanisation and suburbanisation highway and dam construction.As the various habitats become fragmented into "islands," the remaining animal populations crowd into smaller areas, causing further habitat destruction. Species in these small islands lose contact with other populations of their own kind, thereby reducing their genetic variation and making them less adaptable to environmental change. These small populations are highly vulnerable to extinction; for some species, the fragmented habitats become too small to support a viable population.
ENDANGERED SPECIES
Animals like rabbits and insects like flies are extremely common. They are not in danger of dying out or becoming extinct. Yet other animals and plants species are very rare. Their numbers have been greatly affected by environmental conditions that don't support that particular species' survival in their current habitat. These species are listed by environmental researchers as vary rare. They are placed on a register of "endangered species" in danger of dying out for ever
