Wildlife traditionally refers to non-domesticated animal species, but has come to include all plants, fungi, and other organisms that grow or live wild in an area without being introduced by humans. This subsection focuses on anthropogenic forms of wildlife destruction.
This final group is one of secondary effects. All wild populations of living things have many complex intertwining links with other living things around them. Large herbivorous animals such as the hippopotamus have populations of insectivorous birds that feed off the many parasitic insects that grow on the hippo. Should the hippo die out, so too will these groups of birds, leading to further destruction as other species dependent on the birds are affected.
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. The BBC natural history unit in the UK was a similar pioneer, the first wildlife series LOOK presented by Sir Peter Scott, was a studio-based show, with filmed inserts.
Many nations have established their tourism sector around their natural wildlife. South Africa has, for example, many opportunities for tourists to see the country’s wildlife in its national parks, such as the Kruger Park. In South India the Periar Wildlife Sanctuary, Bandipur National Park and Mudamalai Wildlife Sanctuary are situated around and in forests.
