    • Coral reefs: coral mining, pollution (organic and non-organic), overfishing, blast fishing, digging of canals & access into islands/bays Nitrogen Cycle Agricultural/industrial Nitrogen inputs [humans produce 1/3 N2O] to environment currently exceed inputs from natural Nitrogen fixation. Consequence = global nitrogen cycle significantly altered over past century
  17. What does the US Fish & Wildlife Services do?http://www.fws.gov/endangered/index.html
    administer the Endangered Species Act (ESA),  take the lead in recovering & conserving the Nation's endangered species
  18. Why is excess [too much] CO2 such an issue?
    The rate at which we are creating the excess CO2 in the Earth's atmosphere from industrialization, deforestation, & pollution is at a higher rate than plants & oceans can absorb it so = uneven balance.
  19. Will Global Warming stop if we completely eliminate CO2 emissions?
    NO it'll stay in Earth's atmosphere for years so it's important to not just eliminate and/or reduce the emissions but to create long term solutions & options for sustainable renewable clean energy alternatives
  20. What are some of the major sources of anthropogenic climate changing Greenhouse Gases & contributions to Global Warming?
    Greenhouse Gases are created by burning fossil fuels [49%], making cement, burning forests & grasslands [14%] & other human activities [anthropegenic] such as agriculture [13%], & industrial processes [24%]
  21. What are some ways we can control Greenhouse emissions?
    • ~substitute Natural Gas for coal
    • ~promote energy efficiency
    • ~Renewable Energy sources such as solar, wind, geothermal, biomass, and fuel cells
    • ~explore options to capture & store CO2
    • ~Plant more trees & allow them to reach maturity
    • ~Use farmland as a carbon sink
  22. What is recycling?
    Recycling is a process to change materials (waste) into new products to prevent waste of potentially useful materials. Reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) & water pollution (from landfilling) by reduce the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to plastic production
  23. What is Sustainable Energy?

    Technologies that promote sustainable energy include renewable energy sources, such as hydroelectricity,solar energy, wind energy, wave power, geothermal energy, and tidal power,
  25. What is the Greenhouse Effect & how does it work?
    the warming of Earth due to the presence of certain gases in the atmosphere, which let sunlight come in but don't let heat go back out into space. It's attributable to the increasing consumption of fossil fuels, particularly oil & coal, that > emissions of CO2

  26. What is Global Warming?
    A gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of CO2, CFCs, & other pollutants.
  27. What are the effects of Global Warming?
    • ~climate change
