  2. Know List as many local (Pacific NW) environmental issues of which you know. Guessing is OK. Use complete sentences. Evidence After listening to the PowerPoint lecture, come back here and list evidence to explain why your answer to the above question is or is not a good answer. You may also use other outside sources to help you respond. Draw pictures to show alternatives to these environmental issues. Page #

  3. Environmental Issues Information Clarifying ?s - the negative impact of human activity on the earth and environment Environmental issue There are many types! 1. Energy - overuse of fossil fuels, nuclear energy, solar power, and wind farms 2. Pollution - oil spills, ocean dead zones, urban run-off, land fills, smog 3. Habitat destruction - land use, urban sprawl, invasive species 4. Resource depletion - salmon overfishing, logging vs spotted owl, poaching - animal endangerment & extinction Solutions All solutions have both positive and negative impacts Alternative energies 1. Solar A) Passive - heat energy produced by absorption of direct sunlight Example: Windows on the south side of the house B) Active - using mechanical devices to move heat collected from the sun through heating systems Examples: solar panels, flashing lights around stop signs, calculators 2. Wind - (kinetic energy) - turbines used to generate electricity - wind mill farms 3. Hydroelectric - converting the kinetic energy of falling water into electricity Example: Bonneville Dam 4. Biofuel - fuel made from plants (biomass) Example: Corn Page # Summary:
