Guy Laliberte

When you are up there, feeling infinite space, the earth looks like a fragile planet against the immense universe. We are just another fleeting species, passing by. I do believe there is life elsewhere, and we are not alone. But not having found an alternate place for now, it is crucial to take care of the one place we do have.

I do like the thrill of risk-taking, but it's always carefully calculated. I have done many high risk undertakings, but I have always measured the stakes. Not feeding the fear nor the doubt. But I also believe that you need to fuel passion in whatever you do. This is what I am trying to teach my children today.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
