We are rare and precious because we are alive, because we can think as well as we can. We are privileged to influence and perhaps control our future. I believe we have an obligation to fight for life on Earth - not just for ourselves, but for all those, humans and others, who came before us, and to whom we are beholden, and for all those who, if we are wise enough, will come after. ✨ Carl Sagan (2011). Billions & Billions: Thoughts on Life and Death at the Brink of the Millennium, p.74, Ballantine Books
