Sage advice from Carl Sagan



The threat of nuclear war seemed to subside after the end of the Cold War. Nonetheless this presentation by Carl Sagan is as pertinent today as when it was recorded (seems to be a theme for the week). The threat to planet Earth might be different today - climate change and environmental brinksmanship have become our dread fixations - Though sabre rattling by the 'dim leader of the free world' about Iran may give us pause for thought if we imagine ourselves safe.
