• (convenient and cheap cost)
• recreational activities
• (boating, waterskiing)
• thermal pollution by industry
• untreated sewage
• transportation

27
How does it affect ecosystems?

• kills or harms aquatic like
• contaminates our food supply

28
Agriculture
WHY?

• food
• money

29
How does it affect ecosystems?

• fertilizer run-off
• pesticide run-off
• clear cutting for farmland
• habitat loss

30
