Today on Discovery Enterprise we present the thirteenth and final episode of Carl Sagan’s highly acclaimed PBS documentary series – Cosmos: Who Speaks for Earth?
In this final instalment of Cosmos, Carl Sagan leaves us with a sobering message: Human Civilization has to make a choice between life and death.
Carl Sagan said it best with words that are poetic and powerful in their majesty:
“The civilization now in jeopardy is all humanity. As the ancient myth makers knew, we are children equally of the earth and sky. In our tenure of this planet, we have accumulated dangerous, evolutionary baggage — propensities for aggression and ritual, submission to leaders, hostility to outsiders, all of which puts our survival in some doubt. We have also acquired compassion for others, love for our children, a desire to learn from history and experience, and a great, soaring passionate intelligence — the clear tools for our continued survival and prosperity.
Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet earth. But, up and in the cosmos an inescapable perspective awaits. National boundaries are not evidenced when we view the earth from space. Fanatic ethnic or religious or national identifications are a little difficult to support when we see our planet as a fragile, blue crescent fading to become an inconspicuous point of light against the bastion and citadel of the stars.”
