What is the most responsible for wildlife habitat destruction?

Answer 1

There is only one cause- humans who want to expand their ' territory' by destroying forests and homes of lots of animals
Throughout history, the primary cause of species extinction has been the introduction of non-native species into new ecosystems. Imported farm animals, predators brought in to control native pests, and accidental stowaways can severely harm native flora and fauna and upset ecological equilibrium. This is particularly true on islands, where species frequently evolved without competition from predators or intruders. For instance, 75 per cent of all species in the United States that have become extinct were native to the Hawaiian Islands, where 3,900 exotic species have been introduced since European explorers first arrived in 1778. Today, one-fifth of Hawaii's native flora and 50 per cent of the state's indigenous birds are endangered.

Habitat Loss and Poaching Habitat loss is the second most critical factor in species extinction. Worldwide, there is now 20 per cent less forest cover than existed 300 years ago, and there is five times as much land devoted to agriculture. Forests and fields that are cleared for agriculture can sustain only a fraction of the species they formerly held.

Poaching and hunting are another major cause of animal species extinction. In some regions of Africa, hunters in search of much-needed food have wiped out scores of game species. Poaching and illegal trade in animals are US$2 billion to $3 billion global industries, and as long as rhinoceros horns bring US$12,500 per pound on the black market and ocelot pelts fetch US$40,000, exotic animals will continue to be endangered.

In recent years, conservationists concluded that it is ineffective to try saving species one at a time. Most efforts to preserve biodiversity now focus on the maintenance of the habitat necessary for plant and animal survival rather than on particular species. Currently, 6 per cent of all the Earth's land is protected or preserved habitat, although the preserves are not distributed equally across all continents. To that end, the World Conservation Union has set a goal of preserving 10 per cent of each of the Earth's major ecological regions by the year 2000, thereby protecting greater numbers of species from extinction.

Answer 2

The activity of humans is the primary cause of habitat destruction. Farming and logging are two of the activities that cause the most damage, urbanization is another problem.

Answer 3

By deforestation for the construction of buildings and establishment of industries, poaching.

Answer 4

Surface mines.
