HUMAN IMPACT ON ECOSYSTEMS
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, urbanisation, agricultural practices and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Humans have greatly changed the Earth, affecting both the abiotic and biotic environment.
