What are the 3 main environmental problems in the Pearl Valley Delta? Air pollution Water pollution Deforestation
What 3 things contribute to air pollution in the Delta? Chemicals and metal manufacturing Power stations Vehicles
What 2 particular types of air pollution are problematic in the Delta? (Bonus: give details) Smog - Gathering of gases and particles in lower atmosphere Acid rain - pH of below 4.8
