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: -Among the most critically impactful ways that humans have affected the environment is our extraction and consumption of fossil fuels and their attendant CO2 emissions.

Detailed explanation-3: -For thousands of years, humans have modified the physical environment by clearing land for agriculture or damming streams to store and divert water. As we industrialized, we built factories and power plants.

Detailed explanation-4: -Don’t travel by air if you can avoid it because air travel uses up large amounts of fossil fuels and creates greenhouse gases. Dispose of any rubbish responsibly-it can be hazardous to wildlife. Use public transport, cycle or walk instead of using a car. Use facilities and trips run by local people whenever possible.
