Okay, I admit it, I'm not really in the process of colonizing the galaxy.
However, my good buddy Lee Urton has gotten me interested
in the First Millenial Foundation,
an organization dedicated to doing just that (in eight easy steps,
no less!), following the plan laid out in the very interesting book The
Millenial Project, by Marshall T. Savage.
The book also briefly piqued my interest in spirulina, a form
of blue-green algae, which it recommends for human
nutrition and also to help terraform other worlds. As a result, I
tried injesting a bit of spirulina. It was fine, but I did not become
a regular consumer and thus am not "on the algae program".
