Habitat loss happens when natural environments are destroyed or removed. This can occur when forests are cut down or land is used for buildings, roads, or farms. Habitat loss affects many ecosystems.

Tropical rainforests, wetlands, and grasslands have all been reduced in size in different parts of the world. Animals and plants that depend on these areas may no longer find the space or conditions they need. Scientists often measure habitat loss by tracking changes in land area over time.

Habitat loss is studied in environmental science. It is one of the main factors linked to the decline of many species.
