Step 1: Group the problems by where they hit.
Split the effects into human health, nature, and society, so the note covers the full picture rather than only one angle.
Step 2: Explain each group.
On human health, dirty air and water directly cause disease. On nature, pollutants disturb food chains and reduce species variety. On society, pollution adds noise stress, harms tourism and farming, and pushes up healthcare spending.
Step 3: Tie it together.
Because these three areas are connected, pollution in one area (like air) often worsens problems in another (like health spending), making the overall damage larger than any single effect alone.
Final Answer:
Pollution's problems span health, ecosystems, and society together, making it a wide-reaching issue, not a narrow one.
