    2. Using Natural Resources Burn, Baby, Burn Overfishing Mining Pits Pollution of Water Who Will Speak for the Trees?

    3. Burning Fossil Fuels Why do we burn fossil fuels? Transportation Manufacturing Heat & Electricity What are the impacts of burning fossil fuels on… Urban Areas? Rural Areas?

    4. Burning Fossil Fuels Fossil fuels (coal, oil, and natural gas) are a non-renewable source of energy. Formed from plants and animals that lived up to 300 million years ago, fossil fuels are found in deposits beneath the earth. The fuels are burned to release the chemical energy that is stored within this resource.

    5. Burning Fossil Fuels Transportation

    6. Burning Fossil Fuels Transportation Fossil fuels are also overwhelmingly responsible for fueling our transportation system. Our country’s entire transportation infrastructure of pipelines and gas stations is built around fossil fuels. You can drive across the country and find a gas station to fill up your car. That infrastructure is one of the hurdles preventing new fuel sources from competing with fossil fuels. It’s extremely expensive to change a nationwide infrastructure, so to be competitive, new fuel sources must adapt to existing infrastructure.

    15. Burning Fossil Fuels Manufacturing

    16. Burning Fossil Fuels Manufacturing The manufacture of an average desktop computer and monitor uses more than 10 times its weight in fossil fuels. Most of the burning of fossil fuels in factories is for electricity…

    17. Burning Fossil Fuels Heat & Electricity

    18. Burning Fossil Fuels Heat & Electricity The burning of fossil fuels accounts for 70% of the world’s electricity production Coal 52% Natural Gas 15% Oil 3%

    19. Burning Fossil Fuels How is energy obtained by burning fossil fuels? Coal power plants combust the coal in large furnaces creating tremendous amounts of heat. This heat is used to evaporate water in boilers so they convert to steam. The steam expands, causing pressure to increase in the boiler. A steam turbine is placed at the exit of the boiler where it converts energy from the moving steam into mechanical energy.

    32. Overfishing

    35. Overfishing The “nose” and “tail” of the Grand Banks of Newfoundland extend beyond Canada’s 360 km fishing zone into NAFO’s Regulatory Area.

    36. Overfishing – The Turbot War On March 9, 1995 Canadian Coast Guard officials seized the Spanish fishing trawler Estai for using nets that were smaller than permitted. The Estai had tried to get away, cutting its net and fleeing into international waters.

    37. Open Pit Mining This method is used when the deposit is close enough to the surface for mass removal of ore to be economically viable.

    43. Open Pit Mining Impacts Destruction of vegetation Large volume of unused waste rock and overburden that must be stored Disruption of groundwater Production of dust and radon gas from blasts to open pit and actual mining process "The mining industry produces more solid waste than all the municipal landfills in the United States.”
