The Cassini spacecraft took this picture of Saturn and also captured the image of a faint blue dot. This faint blue dot is Earth. From this far away, our home is just another celestial object. It is insignificant in the mind-blowing vastness of space. As Carl Sagan said, "...we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people."
This little blue dot is all that we have. We will not be colonizing other planets any time soon. It is imperative that we do all we can to protect this precious planet. This is not a liberal or conservative concern, but it is a human concern. All the inhabitants of this planet are in this together. Instead of finding ways to kill each other, we should be finding ways to keep this planet liveable.
