Detailed explanation-1: -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.
Detailed explanation-2: -The loss of trees changes the quality of soil which leads to soil erosion, fewer crop production and flooding. The biological cycles (Bio-geo chemical cycles) are altered because of deforestation. The amount of carbon di oxide increases in the earth which leads to global warming.
Detailed explanation-3: -It is a serious environmental concern since it can result in the loss of biodiversity, damage to natural habitats, disturbances in the water cycle, and soil erosion. Deforestation is also a contributor to climate change and global warming.
Detailed explanation-4: -Increased soil erosion by wind and rain, increased flooding. Extinction of wildlife (forest animals and plants). Disruption of the water cycle. Deforestation causes drought and desertification.
