What are the four greatest threats to biodiversity and thus species loss?

Below, we discuss six of the major threats to biodiversity: climate change, habitat loss and degradation, pollution, invasive species, over-exploitation and epidemics. Learn how serious these threats are in contributing to the loss of biodiversity in our planet.

What is the biggest threat to the loss of biodiversity?

Habitat Fragmentation

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.
