Wildlife conservation is the practice of protecting wild plant and animal species and their habitat. Wildlife plays an important role in balancing the ecosystem and provides stability to different natural processes of nature like rainfall(transpiration from plant),changing of temperature(heat evolution by animals),fertility of soil(making of manure by earthworm). The goal of wildlife conservation is to ensure that nature will be around for future generations to enjoy and also to recognize the importance of wildlife and wilderness for humans and other species alike.  Many nations have government agencies and NGO's dedicated to wildlife conservation, which help to implement policies designed to protect wildlife. Numerous independent non-profit 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. An endangered species is defined as a population of a living species that is in the danger of becoming extinct because the species has a very low or falling population, or because they are threatened by the varying environmental or prepositional parameters like (land slides,increasement in temperature above optimum temperature,acid rain) .Wildlife is part of nature which maintain equally distribution of food instead of over use of food by one humans.
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. Habitat loss due to destruction, fragmentation, and degradation of habitat is the primary threat to the survival of wildlife.
- Climate change: Global warming is making hot days hotter, rainfall and flooding heavier, hurricanes stronger and droughts more severe. This intensification of weather and climate extremes will be the most visible impact of global warming in our everyday lives. It is also causing dangerous changes to the landscape of our world, adding stress to wildlife species and their habitat. Since many types of plants and animals have specific habitat requirements, climate change could cause a disastrous loss of wildlife species. A slight drop or rise in average rainfall will translate into large seasonal changes. Hibernating mammals, reptiles, amphibians and insects are harmed and disturbed. Plants and wildlife are sensitive to moisture change so, they will be harmed by any change in moisture level. Natural phenomena like floods, earthquakes, volcanoes, lightning and forest fires also affect wildlife.  
- 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.
- Pollution: Pollutants released into the environment are ingested by a wide variety of organisms. Pesticides and toxic chemical being widely used, making the environment toxic to certain plants, insects, and rodents.
- Overexploitation: Overexploitation is the overuse of wildlife and plant species by people for food, clothing, pets, medicine, sport, and many other purposes. People have always depended on wildlife and plants for food, clothing, medicine, shelter and many other needs. More resources are being consumed than the natural world can supply. The danger is that if too many individuals of a species are taken from their natural environment, the species may no longer be able to survive. The loss of one species can affect many other species in an ecosystem. The hunting, trapping, collecting and fishing of wildlife at unsustainable levels is not something new. The passenger pigeon was hunted to extinction, early in the last century, and over-hunting nearly caused the extinction of the American bison and several species of whales.
- Deforestation: Humans are continually expanding and developing, leading to an invasion of wildlife habitats. As humans continue to grow, they clear forested land to create more space. This stresses wildlife populations as there are fewer homes and food sources for wildlife to survive.
- Population: The increasing population of human beings is a major threat to wildlife. More people on the globe means more consumption of food, water, and fuel, therefore more waste is generated. Major threats to wildlife are directly related to the increasing population of human beings. Low population of humans results in less disturbance to wildlife.The activities like nuclear test ,use of phones,loudspeaker etc produced a harmful radiations which decreased the growth rate of animals and plants.These radiations also change the genetic order of DNA.Nowadays governments were making a law to restricted the use of loudspeaker,fire crackers and many harmful substances.
In 1972, the Government of India enacted a law called the Wild Life (Protection) Act. In America, the Endangered Species Act of 1973 protects some U.S. species that were in danger from overexploitation, and the Convention on International Trade in Endangered Species of Fauna and Flora (CITES) works to prevent the global trade of wildlife, but there are many species that are not protected from being illegally traded or being over-harvested. The World Conservation Strategy was developed in 1980 by the International Union for Conservation of Nature and Natural Resources (IUCN) with advice, cooperation and financial assistance of the United Nations Environment Programme (UNEP) and the World Wildlife Fund and in collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the United Nations Educational, Scientific and Cultural Organization (Unesco)"  The strategy aims to "provide an intellectual framework and practical guidance for conservation actions."  This thorough guidebook covers everything from the intended "users" of the strategy to its very priorities. It even includes a map section containing areas that have large seafood consumption and are therefore endangered by overfishing. The main sections are as follows:
According to the National Wildlife Federation, wildlife conservation in the United States gets a majority of its funding through appropriations from the federal budget, annual federal and state grants, and financial efforts from programs such as the Conservation Reserve Program, Wetlands Reserve Program and Wildlife Habitat Incentives Program.   Furthermore, a substantial amount of funding comes from the state through the sale of hunting/fishing licenses, game tags, stamps, and excise taxes from the purchase of hunting equipment and ammunition, which collects around $2000 million annually. 
- The objectives of conservation and requirements for their achievement:
- Maintenance of essential ecological processes and life-support systems.
- Preservation of genetic diversity that is flora and fauna.
- Sustainable utilization of species and ecosystems.
- Priorities for national action:
- A framework for national and sub-national conservation strategies.
- Policy making and the integration of conservation and development.
- Environmental planning and rational use allocation.
- Priorities for international action:
- International action: law and assistance.
- Tropical forests and drylands.
- A global programme for the protection of genetic resource areas.
- Map sections:
- Tropical forests.
- Deserts and areas subject to desertification.
As major development agencies became discouraged with the public sector of environmental conservation in the late 1980s, these agencies began to lean their support towards the “private sector” or non-government organizations (NGOs).  In a World Bank Discussion Paper it is made apparent that “the explosive emergence of nongovernmental organizations” was widely known to government policymakers. Seeing this rise in NGO support, the U.S. Congress made amendments to the Foreign Assistance Act in 1979 and 1986 “earmarking U.S. Agency for International Development (USAID) funds for biodiversity”.  From 1990 moving through recent years environmental conservation in the NGO sector has become increasingly more focused on the political and economic impact of USAID given towards the “Environment and Natural Resources”.  After the terror attacks on the World Trade Centers on September 11, 2001 and the start of former President Bush’s War on Terror, maintaining and improving the quality of the environment and natural resources became a “priority” to “prevent international tensions” according to the Legislation on Foreign Relations Through 2002  and section 117 of the 1961 Foreign Assistance Act.  Furthermore, in 2002 U.S. Congress modified the section on endangered species of the previously amended Foreign Assistance Act.
Many NGOs exist to actively promote, or be involved with wildlife conservation:
- The Nature Conservancy is a US charitable environmental organization that works to preserve the plants, animals, and natural communities that represent the diversity of life on Earth by protecting the lands and waters they need to survive. 
- World Wide Fund for Nature (WWF) is an international non-governmental organization working on the issues regarding the conservation, research and restoration of the environment, formerly named the World Wildlife Fund, which remains its official name in Canada and the United States. It is the world's largest independent conservation organization with over 5 million supporters worldwide, working in more than 90 countries, supporting around 1300 conservation and environmental projects around the world. It is a charity, with approximately 60% of its funding coming from voluntary donations by private individuals. 45% of the fund's income comes from the Netherlands, the United Kingdom and the United States.
