• loss of biodiversity

• biological magnification

• loss of genetic diversity

Human activities that degrade ecosystems result in a loss of diversity of the living and nonliving environment.  Two ways in which humans frequently harm ecosystems and affect other organisms is through land use and pollution.

How does land use cause a reduction in biodiversity?
