The reasons for human action are well known- land cleared for farming, herding, settlement and industry. Although much attention has been focused on the biologically rich ecosystems such as rainforests, coral reefs and mangrove swamps, widespread alterations have already occurred in the habitats of temperate latitudes such as in the UK.
In the UK, farmland occupies 72% of the [present land area. 5000 years ago, UK was almost entirely covered in forest. Today, the Uk is 0ne of the least wooded countries in Europe. [8% land cover in England and Wales- most of this is recent conifer planting]; land covered by ancient woodland e.g. oak/beech/ash/elm is 2.5%.
There are many examples of species driven to edge of extinction because of habitat destruction. Possibly the best known is the Giant Panda, once found all over China, now confined to a few sites near the city of Chengtu in the Province of Szechwan in western China. The giant panda relies heavily on a diet of bamboo but China's bamboo forests have been converted to farmland. Despite conservation attempts by WWWF [World Wide Fund for Nature (panda emblem)] and breeding programmes in zoos [largely unsuccessful], genetic biodiversity so reduced that species will probably die out.
Fragmented destruction of habitats as well as total destruction can also bring about reductions in biodiversity by reducing the chances of normal dispersion and colonization processes of species and reduces areas for foraging.
Hunting.
People have been responsible for the extinction of species through hunting for food for a long time. Such affects can be traced back to the Stone Age. The loss of large mammals such as the mammoth and sabre toothed tiger has been linked to over hunting.
Large animals which are easy to see coupled with the use of a firearm enhanced out ability to exterminate species in large numbers.
