    YOu see, they do not measure CO2 exhaled by people and animals. They take the number of cars, industries that emit CO2 and based on that, make the emission count. India does not have the industry capability of USA but it has bloody big ammount of people.

    You see! You can pull out statistics about anything! Did you know that cows are significant methane polluters on earth?

    The data consider only carbon dioxide emissions from the burning of fossil fuels and cement manufacture, but not emissions from land use such as deforestation.
    They totally forgot that people emit CO2 too! And cats and cows!

    Seems like the original thread is getting hijacked here.

    Any energy source or method we use to get into space will will have a pollutant footprint, especially if you start counting with the guy waking up early one morning to go to the mine, forest, etc. to start the raw materials needed on their way.

    Rockets work very well... hydrogen + oxygen = a darned good ride with H2O the output. OTEC (Ocean Thermal Energy Conversion) can produce all the hydrogen and oxygen needed using energy from the sun. The only pollution foot print is humans for the job and that produced building facilities and manufacturing equipment and vehicles needed for the task.

    And after all our great efforts to control CO2 emissions by humans, mother nature gets worked up and POP! there goes another volcano like the one in Iceland pumping mega tons of of all kinds of gases including CO2 into the atmosphere .... making the contributions of mankind seem rather puny in comparison.

    Greeny, I think you've hit on one major source of the problem ... the massive "venusforming" done by humans to our planet. Six billion people are just altering the landscape far too much for mother nature to adjust for. Too much forest disappearing each year, too much grasslands turning into dust bowls, too much concrete covering too much area, too many people, too much excess ... has thrown mother nature out of balance. However, such ideas are not "correct political thinking" so shall never be seriously considered.

    Yah its true the original topic is getting diverted. The discussion is turning into pollution rather than going to space.

    Thing is reducing population growth is the best solution. But its a slow process. The governments of the overpopulated country is now trying to make awareness for birth control and making laws to control population.

    More population require more space to live and farm which in turn destruction of more forest.

    So day by day it is getting more essential to find some other planet where human can colonize.

    Primarily, living in space station can be a good starting. But for that we also need a cheap and good transportation system between earth and space.

    Sukumar I like that you actually pay attention what you are told instead of going bersek as an usual "green" activist would do. Open mind is one of the traits I truly value in people. Even I we do not agree, do not think I am agaist you.

    Sxinias, on the contrary, I am against killing people. We might kill the incarnation of another einstein or sagan.Birth control would be still a good thing. I would do a massive effort to rebuild our planets lungs. I am a big pro-alternative space travel since the shuttle and sojuz transport is damn expensive and slugish.

    And the "waste" produced by nuclear fission can easily be reduced by 60%+ simply by recycling spent fuel rods and using them again. (The US Congress has forbidden reprocessing- although France for example reprocesses all their nuclear waste.)

    All the nuclear waste from all the reactors in the USA for the last 50 years could be stored on one football field - stacked 25 ft high.

    This is not a technical problem of waste disposal it is a problem of folks having little or no knowledge of nuclear power.

    Greeny, I also agree with you. If every human in this world plant 3 tree. There will be 18 billion trees in the world. That's really a big forest. Enough to handle huge carbon emission.

    Greeny, I did not take that you were advocating killing people and I am sorry if I gave that impression. I thought that you were just mentioning the obvious; 6 billion people are having a horrendous impact on our planet.
