How do humans live on Mars? ."Mini-Earth" Behind the Scenes.

<P> "67 million people live," Science and Technology Museum in Sichuan tomorrow to carry out, showing how to deal with global environmental change advanced technology </ P> <P> the past 20 years, the global population from 50 billion to 6.7 billion, an increase of nearly 34 .%. .In this increasingly crowded world, how we can continue to survive? The face of increasingly tough environment, energy, food and other issues, how will we respond? Tomorrow morning, by the Museum of Emerging Science and Design of the " .6.7 billion people survive, "Science and Technology Museum will be free to carry out in Sichuan, Chengdu people to show a magical world of the future. .</ P> <P> It is reported that "67 million people living" exhibition by the Chinese Association for Science, Sichuan Association for Science, Museum of Emerging Science and co-sponsored by the China International Science and Technology Convention Center, Sichuan Science and Technology Museum concrete contractor. .Exhibition is divided into "67 million people's food", "67 million people a tool", "67 million people in the environment", "67 million people's energy" and other four themes, each divided into "for now" ."Looking to the future," "deep thinking" in three parts. .Each theme pavilion has a "Where do we want to how to live it", "To live better, we can survive continuous use up the Earth" and other thought-provoking questions. .The exhibition will open to the public free of charge, and continued until June 6. .</ P> <P> yesterday, holding a "survival ID card", the reporter in advance, "butt" all kinds of related experiments and the future - turning off lights for Earth "cool"; two "mini-Earth" .material recycling has been achieved; after moving to Mars will be very different things to eat ... ... how to use cutting-edge technology of high population growth in response to environmental changes brought about? human survival in space in the way of the future, whether the movie "waste-packing member of the Earth ."No truth in the same? reporters to give you" leak the secret. " .</ P> <P> A Energy articles </ P> <P> light "light bulbs blowing balloons" </ P> <P> turning off lights such a trivial matter, and reduce carbon dioxide emissions will have to do? < ./ P> <P> as increasing atmospheric carbon dioxide, the greenhouse effect is becoming more and more heat to the earth. .Global warming is not just a simple rise in temperature, it will trigger a large-scale climate change, and thus a threat to human survival. .Now the concentration of atmospheric carbon dioxide has reached the highest value of 65 million years, scientists have predicted that if the release of carbon dioxide do the same to continue, by 2100, the Earth is higher than the highest temperature 4-6 ℃. .</ P> <P> turning off lights such a trivial matter, and reduce carbon dioxide emissions have anything to do with it? A magic lamp to blow the balloon may be able to tell you the answer. ."In fact, not a light bulb blow up balloons, but greenhouse gases - carbon dioxide." Explanation to the exhibition staff, 100-watt incandescent light for 1 minute power consumption is 1 / 600 degree (kWh), if .power by oil, coal, natural gas and other fossil fuels, thermal power conversion from, then in power at the same time, it will produce 630 ml of carbon dioxide. .</ P> <P> 630 ml of carbon dioxide to have much ability? The bulb blower to tell you: a 100-watt light bulb for one minute, power generation, carbon dioxide can balloon blown volleyball so much. ."So, turning off lights that seem a trivial matter, but also to reduce carbon dioxide emissions for our planet 'cool'." </ P>.
