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 had 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 built-up urban sites—all have distinct forms of wildlife. The Stone Age peoples and hunter-gatherers relied on wildlife, both plant and animal, for their food. In fact, some species may have been hunted to extinction by early human hunters. In some countries, protected areas, wildlife preserves or national parks have been set up to protect wildlife and their natural habitat. Many wildlife species have spiritual significance in different cultures around the world, and they and their products may be used as sacred objects in religious rituals. For example, eagles, hawks and their feathers have great cultural and spiritual value to Native Americans as religious objects.

Wildlife has long been a common subject for educational television shows. National Geographic specials appeared on CBS beginning in 1965, later moving to ABC and then PBS. In 1963, NBC debuted Wild Kingdom, a popular program featuring zoologist Marlin Perkins as host. Destruction of wildlife is happening frequently all over the world. We had a large number of wildlife in all the corners of the world but now their population has become less compared to earlier. Mostly, the animals are killed and poached for their horn, skin, bone, etc. as these fetch easy money.
