Are We Going to Affect the Biosphere?

i think we need to recognize that there are some limits on what genetics can determine. We're learning more and more the biological mechanism by which these other influences determine how gens will express themselves. So i think that we can have a tremendous effect on changing the parimeters within which our biosphere develops. But i don't think tha we can actually determine either our own body futures or the particular futures of other entities on the planet.
