“We, of all the beings that we know of, can think. We can eat, write, build, save. We can predict, estimate, and count. We can preserve food for lifetimes, and in times of crisis, we can find ways to ensure our survival. With each passing generation, our sphere of control of our existence is larger. What if the earth is hit by an asteroid or there is no way to stop global warming? We look to colonize other planets. The fate of our species, in a few years, will not be tied to the fate of the earth. Our home planet must be cared for ... but as we go interplanetary and then interstellar, our control on our lives and the evolution of our species grows. As far as we know, we are the only species that has a say in the development of its future.”
