ENVIRONMENTAL ISSUES II
PP. 435-444
GREENHOUSE AFFECT
• the ability to trap heat
• keeps our planet warm and habitable
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
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
