Work Step by Step
Biodiversity is threatened by human consumption habits. In industrial nations such as the United States, people consume many resources. To be able to use these resources, they have to be extracted from the environment. The action of extracting these resources damages ecosystems and, thus, reduces biodiversity. Conserving resources by reducing human consumption of resources, by reusing the resources, and by recycling will help improve and sustain biodiversity.
