At some point in the distant future, the Earth will be destroyed, whether by a large asteroid impact, by the death of our own Sun, by a nearby supernova or by some other astronomical phenomenon. But there is a much more immediate threat to the survival of humankind, and that is the way we are treating our home planet and other living species. Through astronomy and space science, we have learned to see Earth as a vulnerable world in a big Universe. We urgently need to realise that this small planet of ours deserves to be taken care of. Sentient and intelligent as we are, we have that responsibility.
