What have you done to help the Earth?

In honor of Earth Day, I have a question for everyone on TED.com. What have you done to benefit the Earth? Have you recycled, started a club, raised awarness about the Earth's condition, turned down your heating and cooling ststem? Whatever you have done to help the Earth, I want to you post it right here. And, if you haven't done anything to help the Earth than write about something that you plan on/want to do in the near future.

Who knows, maybe it will inspire more people to contribute to saving our planet!

  • Apr 26 2012: 1. I have planted more than 1,500 trees.
    2. I went to my work on bicycle (20km/1 hr) most of my life.
    3. When I use a car I drive fuel efficient, 16 - 20 km/liter
    4. Similar behavior with other energy consumptions
    5. I found a way for North America to switch completely to fuel-free power. Look for it elsewhere in these conversations.

    1. The CO2-hype. My opinion: the whole CO2-hype is based on lies. Motivation: Compare Earth withe Venus, nearer to the Sun and 250,000 times more kg CO2 on each m2 planet surface.If CO2 really had the greenhouse effect it is blamed for, then the temperature on Venus should be well above ten times its present value.
    2. Incandescence bulbs are cheap, lifetime 1000 hrs, inefficient. CFL lamps are 5 - 8 times more expensive, lifetime 8,000 hrs if burning continuously but only 1,000 hrs if turned on/off depending on need, LED's are more expensive, more efficient and have long lifetime independent from switching on/off, but unpleasant color.
    • Apr 27 2012: Not that I disagree but in regard to venus, wouldn't you also have to take into effect the dissipation of co2 buildup as the atmosphere got thicker, meaning that less and less light could penetrate to the point that the planet itself is whats heating the surface, with the help of thermal clouds? meaning that as the clouds got thicker sun became increasingly less and less effective at penetrating the layer and in turn eventually could only heat the outer layers of the gasses?
      • Apr 27 2012: Hi Harvey

        What comes in has to go out, or else the temperature will increase.
        Twice the energy inflow from the Sun and 250,000 times the quantity of CO2 means that the greenhouse effect on Venus is 500,000 times larger than on Earth.
        The radiation of heat is proportional to the fourth power of the absolute temperature. The fourth root of 500,000 is about 26. So the absolute temperature on Venus should be 26 times the absolute temperature on Earth. The average absolute temperature on Earth is about 280°K. The absolute temperature on Venus is actually less than three times the absolute temperature on Earth.
        Therefor CO2 cannot have the greenhouse effect it is accused to have.
        Everybody should have known that already because there is no proper correlation between the increase of temperature and the increase of CO2 during the last century.

        Presume that the heat from the Sun would be completely absorbed in the top layer of the atmosphere on Venus. Then that layer would radiate the same quantity of heat down as it radiates up. Meaning that the surface would become as hot as the atmosphere.

        But we still have to stop using fossil and nuclear fuel. President Obama would say "Yes we can".
        It can be done within ten to twenty years and pay it with the money we are saving on fuel.
