Explanation: 

Detailed explanation-1: -Habitat Loss. Species endangerment and extinction have three major anthropogenic causes-overhunting or overharvesting; introduction of nonnative species, including the spread of disease; and habitat degradation or loss. All three causes probably were factors in prehistoric as well as modern times.

Detailed explanation-2: -The Report finds that around 1 million animal and plant species are now threatened with extinction, many within decades, more than ever before in human history. The average abundance of native species in most major land-based habitats has fallen by at least 20%, mostly since 1900.

Detailed explanation-3: -Habitat destruction is the elimination or alternation in an area or environment required for animal and plant species survival. It is a primary cause of the extinction of plants and animal species.
