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.
Why is Earth losing its greenery?
Growing energy requirements led to the clearing up of large tracts of land for solar energy, wind energy and other power plants. Increasing forest fires are causing even more loss of forest cover. Decreasing air moisture due to climate change is causing declining plant growth.
What is global global warming?
Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere.
