ENVIRONMENTAL ISSUES II

• PP. 435-444

2
GREENHOUSE AFFECT

• the ability to trap heat
• keeps our planet warm and habitable

3
GLOBAL WARMING

• Excess CO2 released from burning of fossil fuels
• Possible correlation between temperature and CO2
  levels
• Adds to the greenhouse to trapping heat
• Could affect amphibian/reptile development as
  well as weather and agriculture

4
ACID RAIN

• Burning fossils fuels produces CO2, H2O water,
  and other gases
• Burning of coal produces H2SO4 (sulfuric acid)
  and burning of gasoline produces HNO3 (nitric
  acid)
• These pollutants enter the atmosphere to form
  acidic water (acid rain)
• Some bodies of water can buffer the effects of
  acid rain
