The politics of today has the same round of ever increasing growth. We know that to continue growing without destroying the habitability of large tracks of the planet we will have to mind asteroids and other planets. In other words that the system of plunder we have grown so accustomed to will continue.
Unless and until something stronger than us or our technology stops us.
Stopping ourselves seems to be impossible. The way in which evolution has given us to think that we can do whatever physics allows us with no other thought than selfish ones, will carry us into space. It is such a small way of thinking.
