A good argument for making sure our planet stays habitable. Caring about the environment isn't just for hippies anymore!

That is it. When you become very aware of just how amazingly far away everything else is, fighting over a speak of dust and the only home we have seems absolutely ridiculous.

A great long form video on this is "Shouting at stars : A history of interstellar messages". It really highlights just how empty it all is. https://www.youtube.com/watch?v=uFI5WpK2sgg

Works up until the earth becomes uninhabitable in 600M years, before then humans are going to need to find and colonize a different planet.
