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. Humans affect the quality, availability, and distribution of Earth's water through the modification of streams, lakes, and groundwater. The activities of humans have significantly altered the biosphere, changing or destroying natural habitats and causing the extinction of many living species.
