I found this video on YouTube, one of my absolute favourite pieces from Carl Sagan’s magnificent series Cosmos: a Personal Voyage (episode 8, ”Journeys through Space and Time”). An excellent message to be absorbed by all of humanity.
”What we do with our world, right now, will propagate down through the centuries and powerfully affect the destiny of our descendants. It is well within our power to destroy our civilization, and perhaps our species as well. If we capitulate to superstition, or greed, or stupidty we can plunge our world into a darkness deeper than time between the collapse of classical civilization and the Italian Renaissaince. But, we are also capable of using our compassion and our intelligence, our technology and our wealth, to make an abundant and meaningful life for every inhabitant of this planet. To enhance enormously our understanding of the Universe, and to carry us to the stars.”
