Dear student,
- Human activity is by far the biggest cause of habitat loss. The primary individual cause of loss of habitat is the clearing of land for agriculture. An estimated 177,000 square kilometres of forests and woodlands are cleared annually to make space for farming or in order to harvest timber for fuel and wood products. Estimates suggest the Earth has lost about half of its forests in 8,000 years of human activity, with much of this occurring in recent decades.
- And its not just forest clearing that leads to habitat loss. The loss of wetlands, plains, lakes, and other natural environments all destroy or degrade habitat, as do other human activities such as introducing invasive species, polluting, trading in wildlife, and engaging in wars. This destruction of habitat also involves marine zones and the ocean, with urbanisation, industrialisation and tourism all aff ecting habitats in coastal areas.
