    • Pollution & the Environment
    • Littering
      • Litter is any material that has been left where it is not meant to be.
      • Litter is the most visible sign of pollution. It is ugly and can cause harm to people, wildlife and our waterways.
      • Litter is wasteful and costly to clean up.
      • Litter also affects the way tourists view our state.
      • Cleanup costs the U.S. almost $11.5 billion each year.
      • Cigarette butts are the most common piece of litter, but beverage containers account for 40-60 percent of most total litter volume.

    • The Great Garbage Patch
      • This patch of garbage floating in the Pacific ocean is roughly twice the size of Texas and contains about 3.5 million tons of trash.
      • These type of effects of pollution violate our basic human rights for clean air and water.
      • Every bit of plastic that has ever been created still exists, except for a small amount that has been incinerated, releasing toxic chemicals.
    •  
    • Water Pollution
      • Access to water is a Fundamental human need, but according to the UN a third of the world’s population live in countries with moderate to high “water stress” meaning that the annual water supplies drop below 1,700m3 per person.
    • Facts
      • Peri-urban and rural areas usually have poor access to adequate water supply.
      • In high-income countries, the quality of the water supply is a primary concern.
      • 50 litres a day are required to supply the basic requirements of an individual.
    • Chemical Contaminants of Water: Naturally Ocurring
    • Industrial sources & human dwelling
    • Water treatment or materials in contact with drinking water
    • Cyanobacteria
      • US – The system that the Congress created to protect the nation’s waters under the Clean Water Act of 1972 today often fails to prevent pollution .
      • Compiled data prove that 200,000 facilities have permits to discharge pollutants.
      • The Times interviewed more than 250 state and federal regulators, water-system managers, environmental advocates and scientists:
      • The research shows that an estimated 1 in 10 Americans have been exposed to drinking water that contains dangerous chemicals or fails to meet a federal health benchmark.
      • Because most of today’s water pollution has no scent or taste, many people who consume dangerous chemicals do not realize it, even after they become sick.
    • To keep in mind
      • With over 70% of the planet covered by oceans, people have long acted as if these very bodies of water could serve as a limitless dumping ground for wastes.
      • Raw sewage, garbage, and oil spills have begun to overwhelm the diluting capabilities of the oceans, and most coastal waters are now polluted, and marine wildlife is beginning to suffer.
    • Clever adverstising for clean waterways
    •  
    • 1963, Clean Air Act: The EPA (environmental protection agency) set out standards for what was to be considered “ criteria pollutants”. Several of these original pollutants were Carbon Monoxide, Sulfur Dioxide, lead, etc. As of 1970's there were two types of quality air standards set out by the EPA: primary standards: meant to protect human health secondary standards: aimed to protect welfare like crops, livestock, visibility, etc.
    • EPA discouraged Smoke Stacks as the stacks were spreading the smoke and causing acid rain. -acid rain is caused from sulfur dioxide reacting with water molecules and elevating hydrogen ion levels. -negative effects of plants and animals -diminishes the nutrient content in soil which results in less vegetation; affecting live stock -you may suffer asthma and lung problems over time. -Chicago's level of sulfer oxide is .015 parts per million, -highest rated city, Pittsburgh, which has near .025 ppm of sulfer oxide .
      • Chicago Tribune analysis of federal data:
      • Cook County is ranked worst in the nation for dangerous air pollution, based on 2005 data
      • Chicagoans face some of the highest risks in the nation for cancer, lung disease and other health problems (linked to toxic chemicals)
    • Chinese Ministry of Health says lung cancer is a leading cause of death due to air pollution from factories -Much of the pollution over Los Angeles originates in China, according to the Journal of Geophysical Research.
    • -U.S. vehicle emissions contribute 45% to global warming -Vehicle exhaust contributes to: -60% of carbon monoxide emissions(US) -95% in large cities -Every year 335,000 Americans die of lung cancer, which is a direct result of air pollution. Ways to cut down emissions: -Don ’t buy products that come in aerosol spray cans -Carpool with friends and coworkers -Don ’t smoke
