Trashing Earth?

BTW: I kicked off that panel with moderator’s prerogative by showing a short clip:

New Rule: Make Earth Great Again on Real Time with Bill Maher (HBO) – Stop Trashing Earth Because We’ve Got Mars as ‘Back-Up’ (Video).

Aired on April 21, 2017, in honor of Earth Day, Maher called on his fellow humans to save this planet instead of trying to colonize Mars. I felt it important to show the video clip as an example of a particular attitude regarding Mars – a public risk that should be heard by those advocating humans to Mars.
