Wildlife traditionally refers to non-domesticated vertebrates, but has come to broadly reference to all wild plants, animals and other organisms . Domesticating wild plant and animal species for human benefit has occurred many times all over the planet, and has a major impact on the environment, both positive and negative. Wildlife can be found in all ecosystems. Deserts, forests, rain forests, plains, grasslands, other areas including the most developed urban sites, all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that wildlife around is affected by human activities. Humans have historically tended to separate civilization from wildlife in a number of ways including the legal, social, and moral sense. Religions have often declared certain animals to be sacred, and in modern times concern for the natural environment has provoked activists to protest the exploitation of wildlife for human benefit or entertainment.
Wildlife conservation is the practice of protecting endangered plant and animal species and their habitats. Among the goals of wildlife conservation are to ensure that nature will be around for future generations to enjoy and to recognize the importance of wildlife and wilderness lands to humans.Many nations have government agencies dedicated to wildlife conservation, which help to implement policies designed to protect wildlife. Numerous independent nonprofit organizations also promote various wildlife conservation causes. Wildlife conservation has become an increasingly important practice due to the negative effects of human activity on wildlife. The science of extinction. An endangered species is defined as a population of a living being that is at the danger of becoming extinct because of several reasons. Either they are few in number or are threatened by the varying environmental or predation parameters. Major threats to wildlife 
•Habitat loss: Fewer natural wildlife habitat areas remain each year. Moreover, the habitat that remains has often been degraded to bear little resemblance to the wild areas which existed in the past. •Climate change: Because many types of plants and animals have specific habitat requirements, climate change could cause disastrous loss of wildlife species. A slight insects are harmed and disturbed. Plants and wildlife are sensitive to moisture change so, they will be harmed by any change in moisture level. •Pesticides and toxic chemical: Widely used, making the environment toxic to certain plants, insects, and rodents. •Unregulated Hunting and poaching: Unregulated hunting and poaching causes a major threat to wildlife. Along with this, mismanagement of forest department and forest guards triggers this problem. •Natural phenomena: Floods, earthquakes, volcanoes, lightning, forest fires. •Pollution: Pollutants released into the environment are ingested by a wide variety of organisms. •Over-exploitation of resources: Exploitation of wild populations for food has resulted in population crashes (over-fishing and over-grazing for example) •Perhaps the largest threat is the extreme growing indifference of the public to wildlife, conservation and environmental issues in general.[ NEED FOR WILDLIFE CONSERVATION
Everything thing on the planet is interconnected .All of us know that we are connected to the wildlife through a cycle called food cycle and if one of the member in this cycle is affected the other will also be affected. Human for his benefit had started interfering with the environment which is not correct. Our ancestors also used to hunt animals but they used to take care of one thing whether it is a young animal or an old if it was old then only they used to hunt him. They never hunted a young animal because they knew that would one day lead to the extinction of that animal. We always think...
