If a little farther down the line, with some genetic manipulation, a genome tweaked here and there, and some rooting compound or whatever, We should be able to genetically introduce a biological addition, that enhances our blood's abilities and efficiency. What I was thinking, is crossing a plant gene, Chlorophyll, into our blood, then we could photosynthesize all of our energy needs instead of having to raep the Earth with plowshares, and enslave whole other species for food. All we'll need is water, and a drop of phostrogen now and then. And of course, we would all be lovely shades of green, so there'd be no more racism, or colour prejudice. Surely someone could get started on this now, then we could have a truly green Olympic experience, for 2012, and the World might not end after all.
