Hacking the human body?

This article about hacking the human body gives a few details about one pharmacologist’s idea of how we could reduce our impact on the environment.

I applaud the direction that he’s heading which is, in a nutshell, if humans ate less meat, were smaller, had fewer children, and were nicer we could save the planet and have more resources to share.

Fair enough.

The burning question in the back of my mind, however, is that if someone wants to make us smaller, weaker, nicer, and less in number, how is he avoiding accusations that he’s preparing us for an alien invasion, and not in a good way?
