Is extinction a natural process?

Extinction is a natural phenomenon: After all, more than 90 percent of all organisms that have ever lived on Earth aren’t alive today. But humans have made it worse, accelerating natural extinction rates due to our role in habitat loss, climate change, invasive species, disease, overfishing, and hunting.

How have humans caused the extinction of some species?

Humans also cause other species to become extinct by hunting, overharvesting, introducing invasive species to the wild, polluting, and changing wetlands and forests to croplands and urban areas. Even the rapid growth of the human population is causing extinction by ruining natural habitats.

How are humans affected by extinction?

Scientists have also discovered links between the incidence of West Nile virus and hantavirus and local reductions in biodiversity. Animal extinctions may also rob humans of valuable medical advancements. Many different species have unique bodily processes that can offer insight into curing human disease.
