The document discusses several key factors that contribute to human impact on the environment:
- Deforestation occurs when forests are removed to make way for other land uses like agriculture, livestock grazing, or development.
- Overpopulation places strain on natural resources as population growth exceeds the environment's carrying capacity.
- Pollution from activities like fossil fuel use and industrial/agricultural waste contaminates air, water, and land.
- Overuse and wastage of natural resources like mining, fishing, and logging deplete resources faster than they can regenerate.
