    That could help in more than just food supplies. It said they use 12X more CO2, so especially gen modded plants could be used as 'weeds' with the express purpose of soaking up CO2, helping the environment.

    All plants soak up CO2, the question is what happens to it after the plant dies. It is often irrelevant how fast it gets soaked up.
    I have heard good arguments that a large part of the cause of global warming is soil degradation by farming and that a large part of the solution to global warming is better farming practices that put carbon into the soil. However it seems to be politically more important to only talk about fossil fuels.

    Are there quantitative data on the levels of CO2 from bad farming methods V the level of CO2 from fuels? I don't know, just seems to me with literally tens of millions of vehicles belching away 24/7 would be shoving more CO2 into the atmosphere than farming. Of course I am just guessing.

    I don't see how you think understanding evolution has anything do with this.

    According to this:
    http://www.epa.gov/climatechange/ghgemissions/global.html
    33% of all C02 produced is from land use and agricultural practices.
    Transport is a mere 13%.
    I am not sure where fertilizer production was classified but it too is a big one.

    That's because you have no imagination nor intelligence to be able to understand how.
