I finally got around to watch Interstellar, and liked it very much. I thought it was very moving at times, the story was tight, and I like well made science fiction movies in general.
It also brought up the topic of sustainability vs space colonization. To me, those go hand in hand. They both have to do with big picture questions. And knowledge from each may well inform the other. For instance, what we learn from sustainability will be of help if (when?) we create space colonies or terraform other planets, and what we learn from those will give us valuable information about how to live in a more sustainable way back on Earth. (Although we probably should have figured that our before we get around to space colonizes and/or terraforming.)
In the short and medium term, we need to learn to live in a more genuinely sustainable way. (Which will require significant reorganization of how we do just about everything, including our institutions.)
In the medium and long term, we need to explore space further, and learn to move beyond this planet. We need, as so many points out, to become an multi-planet species. We need to branch out. It’s what life does. It’s part of our built-in draw to adventure and exploration. It’s how Earth will propagate. It’s what’s necessary if Earth life is to continue beyond the lifespan of this one planet and solar system. It’s what’s prudent, considering that having just one location for Earth life is far more precarious than two, or more.
All life propagates, and Earth is a living system, so why wouldn’t Earth propagate? In that sense, we are in service of Earth life. We are the part of Earth that may be able to make it happen.
And although Interstellar contrasts sustainability with space colonization, it’s the type of movie that makes these ideas more mainstream. It’s part of spreading these ideas, making them familiar, and even attractive.
