There may be life on other worlds. There may even be life on worlds close to our own. There are, without question, many unknown life forms right here on Earth, right now.

Will we find them, or will we trample over them like we have so many on our own world, removing them from the universe in the process of our own inevitable expansion, before we even knew they were there?
