| Question | Answer |
|---|---|
| Know the 5 methods of waste disposal. | Landfills, Incineration, Source reduction, Composting, Recycling |
| What is the most common waste disposal methods in the US? | Landfills |
| what are two problems with the US waste disposal method? | Water pollutants, Aesthetically unpleasant |
| What are some recycling initiatives in the US? | Mandatory recycling laws (15 states), Bottle Bills (10 states) |
| What can you do to help reduce the amount of solid waste generated? | Buy durable items, Buy recycled goods and recycle, Buy beverages in refillable containers, Rechargeable batteries, Reduce junk mail, Lobby for trash separation, Choose items w/ minimal packaging & reduce number of bags used, Compost yard |
| most fundamental method of reducing waste | prevent it from being produced |
| reduce and reuse | saves natual resource, reduce toxicity, reduces cost |
| benefits of recycling | Saves money, raw materials, and land, Encourages individual responsibility, Reduces pressure on disposal systems, Lowers demand for raw resources, Reduces energy consumption and air pollution |
| Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). | 1984 |
| Love canal | 1892 = canal for navigation and hydropower,1920 sold at auction, hooker dumped 20,000 lbs of waste until 1953, 1990 site being resettled |

| What is urban sprawl and what are 3 reasons for it? | wealthy subarbs, tract development, ribbon sprawl |
| Be able to recognize the 9 problems with unplanned growth. | air pollution, energy efficiencies, death of central city, loss of open space, loss of farmland, water pollution, space, foodplain problems, other |
| What is smart growth? | growth without sprawl |
| problems of 1960 | air pollution, water pollution, chemical contamination |
| National Environmental Policy Act (NEPA) 1969 | federal agencies to consider environmental consequences of actionsproduces publicly reviewable document on this analysis: Environmental Impact Statement (EIS) |
| Problems of 1970 | water and air pollution, oil embargo, love canal, 3 mile island |
| NEPA | 1969 |
| clean air act | 1970 |
| Federal Coastal Zone Management Act | 1972 |
| endangered species | 1973 |
| clean water act | 1977 |
| hazardous waste protection | 1976 |
| problems in 1980s | Exxon Valdez oil spill, Thinning ozone layer, Global warming, Acid Rain, Famines in Africa |
| problems in 1990s | Over fishing, Climate Change, Invasive Species, Biodiversity Loss, Deforestation, Persistent Organic Pollutants, World Population |
| ESA | 1. Bans import and sale of endangered species or products, 2. Prohibits “taking” of any endangered species, 3. Prohibits federal agency programs and projects that harm endangered species |
