Wildlife refers to all non-domesticated plants, animals, and other organisms. Domesticated organisms are those that have adapted to survival with the help of (or under the control of) humans, after many generations. 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, rainforests, plains, and 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 the world is impacted by human activities.

Humans have historically tended to separate civilization from wildlife in a number of ways including the legal, social, and moral sense. This has been a reason for debate throughout recorded history. 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. Literature has also made use of the traditional human separation from wildlife.

Fuelled by media coverage and inclusion of conservation education in early school curriculum, Wildlife tourism & Ecotourism has fast become a popular industry generating substantial income for poor nations with rich wildlife specially in Africa and India. This ever growing and ever becoming more popular form of tourism is providing the much needed incentive for poor nations to conserve their rich wildlife heritage and it's habitat.
