Explanation: 

Detailed explanation-1: -The single biggest cause of extinction today is habitat loss. Agriculture, forestry, mining, and urbanization have disturbed or destroyed more than half of Earth’s land area.

Detailed explanation-2: -When a habitat is destroyed, the plants, animals and other organisms that occupy the habitat have reduced their carrying capacity or ability to survive, to the point that populations decline and become extinct.

Detailed explanation-3: -There are many causes of habitat loss, including land conversion for development from growing populations, mining for materials, harvesting lumber for paper products and, of course, agriculture.

Detailed explanation-4: -Scientists at Southampton University say a combination of poaching, habitat loss, pollution and climate change will cause more than 1, 000 larger species of mammals and birds to become extinct over the next century. Among the species threatened with extinction are rhinos and eagles.
