Direct or indirect actions by humans have resulted in the decrease of biodiversity. … Some of the direct human drivers are changes in local land use and land cover, species introductions or removals, external inputs, harvesting, air and water pollution, and climate change (Climate, 2005).
What are five ways that humans could decrease biodiversity in an ecosystem?
3 Humans depend on the living world for the resources and other benefits provided by biodiversity. But human activity is also having adverse impacts on biodiversity through overpopulation, overexploitation, habitat destruction, pollution, introduction of invasive species, and climate change.
