Carl Sagan on the  now iconic “pale blue dot” photo.
This video is worth ten minutes of your time.

These ideas came to mind after viewing the video:
• Earth will remain on track, orbiting around our sun, long after we have returned to dust.
• Our biosphere supports a wealth of life operating within a fixed range of variables.
• The Marxist notion of Nature as an endless source of raw materials is as dated as the Dodo.
• If we do not act as agents for positive change no one else will.
• “All that is necessary for the triumph of evil is that the good do nothing.” While I cannot find the correct attribution for this quote (Burke, Jefferson, Plato?), the power of that thought is timeless.
