  • Saving Our Planet
    One “Helping” Hand at a Time
  • Global Warming
    Definition: the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.
    Effects:
    • changes in rainfall patterns
    • a rise in sea level
    • a variety of effects on humans, plants, and wildlife
  • Did you know?
  • Global warming is mainly caused by human activity!
  • The Greenhouse Effect
    • The greenhouseeffect is the rise in the Earth’s temperature due to gases such as carbon dioxide, nitrous oxide, and methane.
    • These gases are called greenhouse gases because they trap in the heat and energy from the Sun in order to warm the Earth. (Think of an actual greenhouse around the Earth.)
    • These gases are the Earth’s greenhouse.
    • Without these gases, the Earth would be approximately 60°F colder, which would make it impossible to live.
  • Did you know?
  • Humans are damaging the atmosphere by burning fossil fuels.
  • Fossil Fuels
    • Fossil fuelsare substances found below the Earth’s surface that can be used as a source of energy.
    • Examples of fossil fuels include:
    • petroleum
    • natural gas
    • coal
  • Natural Gas
    Petroleum
    Coal
  • Did you know?
  • You send greenhouse gases into the air every day!
  • Greenhouse Gases
    You send greenhouse gases into the air when you:
    • Watch TV
    • Run the AC
    • Use the microwave
    • Use the hair dryer
    • Most of these actions require electricity, which comes from power plants.
    • Most power plants burn fossil fuels, such as coal and oil, which produces greenhouse gases.
    • These gases are what damages our Earth’s atmosphere.
    Greenhouse Gases
  • Did you know?
  • You can make a difference if you reduce, reuse, and Recycle!
  • Reduce— to use less
    • Conserve energy, water, and non-renewable resources.
    • Turn lights off when you leave a room.
    • Don’t leave cell phone chargers, hair dryers, etc. plugged in—they use electricity even when they are not on.
    • Take cloth grocery bags to the store with you to put your groceries in.
    • Don’t leave your television on at night.
    • Take showers instead of baths and turn the water off when you are shampooing your hair.
  • Reuse—to clean or repair something old and use it again.
    • Make crafts using cans (pencil holders)
    • Make quilt pieces out of used clothing
    • Make Halloween costumes out of used clothing.
  • Recycle- to make new products from old ones.
    • This saves energy; it takes a lot less energy to make products out of recycled material than it does to make products out of raw material.
    • Since recycling saves energy, it saves fossil fuels.
    • Recycling also produces less pollution.
  • Did you know?
  • You can recycle items other than paper, glass plastic and aluminum.
  • Athletic Shoes
    • Nike will recycle any brand of athletic shoe through it’s Reuse-a-Shoe program.
    • You can drop them off at any Niketown store or Nike Factory store. You can also mail them in.
    • The company uses the footwear to make sports surfaces for basketball courts, tennis courts, running tracks, and playgrounds.
    • To date, app. 20 million pairs of shoes have been recycled worldwide through this program.
  • Techno-trash
    • VHS tapes, game cartridges, digital cameras, MP3 players, cords, cables, cassettes, VCRs, and even computer monitors can all be recycled!
    • A company called Greendiskwill reprocess this technology in an eco-friendly way.
    • You can mail your techno-trash to the company.
  • Handheld Devices
    • You can recycle old cell phones and pagers
    • Drop them off at Staples , which has partnered with CollectiveGood, (a nonprofit organization that reuses the phones or metals inside them).
  • Did you know?
  • When you recycle plastic…
    You save petroleum!
  • When you recycle paper…
    You save trees!
  • Lend a helping hand to your planet!
