How do we depend on biodiversity?

What are 3 ways in which humans depend on biodiversity?

Human dependence on biodiversity extends beyond the food we eat, the air we breathe, and the water we drink. This dependence has been classified into four main services—provisioning, regulating, cultural, and supporting—and each is essential to human health (Millennium Ecosystem Assessment 2005).

What are some examples of biodiversity?

Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can’t even be seen by the naked eye.
