Humans impact the physical environment in many ways: overpopulation pollution burning fossil fuels and deforestation. Changes like these have triggered climate change soil erosion poor air quality and undrinkable water.

How does human activities affect the ecosystem?

Impacts from human activity on land and in the water can influence ecosystems profoundly. Climate change ocean acidification permafrost melting habitat loss eutrophication stormwater runoff air pollution contaminants and invasive species are among many problems facing ecosystems.

How human activities destroy the ecosystem?

However many ecosystems have been degraded from human activities that destroy the environment. Common human activities that can harm biodiversity include destruction of natural vegetation for agricultural and urban development overexploitation of natural resources and the introduction of invasive species.
