Pollution Putting substances that cause unintended harm into the air, soil, or water
GREENHOUSE AFFECT the ability to trap heat keeps our planet warm and habitable
GLOBAL WARMING Excess CO 2 released from burning of fossil fuels Possible correlation between temperature and CO 2 levels Adds to the “greenhouse” to trapping heat Estimated that earth’s average temp with increase by 2 degrees in the next 100 years.
Ocean Acidification CO 2 dissolve rate increases with increasing temperature carbon dioxide (CO 2 ) reacts with bicarbonate (H 2 CO 3 ) to produce carbonic acid (HCO−) and carbonate (CO2−) and H+ Leads to acidification
LAND AND WATER POLLUTION Bioaccumulation: pollutant from the environment enters the food chain through the lowest level Biomagnification: increase in concentration of a pollutant moving up the food chain
