NEET BIOLOGY

Detailed explanation-1: -Habitat loss poses the greatest threat to species. The world’s forests, swamps, plains, lakes, and other habitats continue to disappear as they are harvested for human consumption and cleared to make way for agriculture, housing, roads, pipelines and the other hallmarks of industrial development.

Detailed explanation-2: -Habitat loss from exploitation of resources, agricultural conversion, and urbanization is the largest factor contributing to the loss of biodiversity. The consequent fragmentation of habitat results in small isolated patches of land that cannot maintain populations of species into the future.

Detailed explanation-3: -The IPBES (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services) has identified five key drivers of biodiversity loss: changes in land and sea use; direct exploitation of natural resources; climate change; pollution; and the invasion of alien species.

Detailed explanation-4: -The human population requires resources to survive and grow, and those resources are being removed unsustainably from the environment. The three greatest proximate threats to biodiversity are habitat loss, overharvesting, and introduction of exotic species.

Detailed explanation-5: -Habitat loss-due to destruction, fragmentation, or degradation of habitat-is the primary threat to the survival of wildlife in the United States.
