Overpopulation, pollution, fossil fuel combustion, and deforestation are all consequences of humans on the physical environment. Changes like these have resulted in climate change, soil depletion, poor air quality, and undrinkable water. Volcanic eruptions, ocean tides, Earth's orbital changes, solar fluctuations, and internal variability are all natural factors that influence and change the planet's climate. is a form of cooling that happens in a short amount of time.
