Climate Change

[Godfather]

Granted, but nuclear power is A LOT safer than it's portrayed as being, usually by environmentalists. And while the waste can be an issue, it seems like Earth's lifeless moon would be a great repository for nuclear waste, and with the cost of space flight coming down thanks to the likes of SpaceX, I'm sure it would become economical as well.

That'd be cool if they could do it in our lifetime. I think they'll need to absolutely perfect rocketry first though... can you imagine a ship loaded with tons of nuclear waste needing to abort launch over the US or the ocean? Bad news

Pretty cool work being done to burry it so it's safe for thousands of years, but the interesting problem there is what if we forget about it and humans in the far future stumble across it thinking it's treasure, say for example like we did with the Pyramids? How do we write warnings on them so that they're universally heeded, regardless of language or culture. Interesting problem to think about.
