What Mars says about the Earth

.
Mars has much to teach us about running a planet.  What a lovely home we have--with its deep blue sky, sparkling sun, mostly clear air, and clean green landscapes!


In contrast, the dust of Mars is everywhere--turning the sky red, casting the landscape into a reddish gloom.  Dust would fill your vehicle, your spacesuit, and your habitat.  We could live there, but we'd have to manufacture every last resource--even the air to breathe.
