Pollution
I. Water Pollution 1. Pollution is so widespread, because it is easy to dump waste into a river or the ocean
2. Three main point sources generate most water pollution: – Water-Using Industries: heavy metals (harm infants & fetuses) – Municipal Sewage – Agriculture
3. Nonpoint sources: – Urban Storm Run-Off : oil, anti-freeze, detergents, lawn fertilizers Cultural Eutrophication
The Everglades & Water Quality Sugarcane field discharge – A potential source of pollution killing the Everglades Pump stations deliver dirty water to the Everglades
Historic Flow of Everglades vs. Present-Day Flow
A. Impacts of Water Pollution 1. On aquatic life: – water becomes oxygen-starved and fish die – fertilizers from farms cause excessive aquatic plant production 2. Human diseases
3. Agriculture in water pollution: Animal Feeding Operations (AFOs): • An agricultural operation where livestock are kept and raised in confinement. Each year, a l, 400 -pound lactating cow producing 70 pounds of milk per day excretes the following: • 300 pounds of nitrogen • 45 pounds of phosphorus • 165 pounds of potassium
Aral Sea, 1989 & 2014 The Aral Sea in the former Soviet Union has shrunk dramatically in area and volume due to extensive diversion of water for irrigation.
4. Waterborne Illnesses & Infectious Diseases: –Cholera, typhoid, hepatitis, dysentery, E. coli *Consider that waterborne diseases are the cause of approximately: -Half of all deaths of children in the developing world -4. 6 million deaths among children and adult -4 billion cases of diarrhea a year -80% of all illnesses in the developing world -One billion cases of illness at any one time Amoebic dysentery in colon biopsy

II. Land Pollution 1. product packaging biggest contributor: – ½ of solid waste in U. S. in landfills – other ½ recycled or incinerated *About 2 kilograms (4 pounds) of solid waste person is generated daily in the United States.
Solid Waste Sources, before & after recycling Paper products are the largest part of U. S. solid waste, followed by food and yard waste. Recycling can reduce solid waste considerably…
Industrial Legacy: Abandoned factories, mines, and landfills often leave extensive pollution behind…
2. Toxic Pollutants – toxic wastes: heavy metals, PCB oils, cyanides, strong solvents, acids – burial of waste was accepted method… – burial sites have leaked (i. e. : Love Canal, NY) – https: //www. youtube. com/watch? v =Kjobz 14 i 8 k. M
