Carl Sagan’s wise words about the only home we’ve ever known:
“Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves. The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. … Like it or not, for the moment the Earth is where we make our stand.”
We must take care of the Earth, or we’ll find ourselves without a home soon. While NASA and the movies like to make going to Mars seem real, the reality is, the future of our species and many others on this planet depends on what we do in the next few years.
