Natural factors have a significant impact on the environment.
However, it is largely disrupted by man-made reasons.
Volcanic eruptions, floods, forest fires, earthquakes, and drought are all natural factors that have an impact on the ecosystem.
Deforestation, pollution, ozone depletion, growing population and its needs and global warming are examples of man-made environmental factors.
Final answer:
Hence, the natural factors affecting the environment are volcanic eruptions, floods, forest fires, earthquakes, and drought, and the man-made factors affecting the environment are deforestation, pollution, ozone depletion, growing population and its needs and global warming.
