I would argue for mixed use of hazardous industries and residential/commercial properties. There is a long history of forcing the pollution generate through your daily life onto lower income communities. If you take a poop, the sewage treatment plant should be in your neighborhood. Drink water, the water treatment plant should be in your neighborhood, use electricity, electricity generation in your neighborhood.
In other words, don't force your crap on to somebody else.
> Yep. And those reasons are why people touched it a few times and never came back.
And it changed the world forever. Probably contributed to avoid the cold war to turn hot. Not to mention we got diapers out of it, and a healthy space program that made amazing things possible like the GPS.
> Hum... Nope. People were already sending boats across that specific ocean for centuries.
I'm also pretty sure some people said things like "We will soon have colonies on the moon" shortly after Neil Armstrong stepped off that Lunar Lander ladder.
Also: When Columbus set sail, he could reasonably assume that he would see his home again. Big boats and long sea voyages were not a new technology in his time. When NASA started the Apollo Missions, they had them planned out from start to finish and knew exactly how that would work.
So yes, once in a while, humanity does something amazing, that seems a bit far fetched, but still reasonable. What humanity usually doesn't do, is something that it has absolutely no plan on how to do it.
