We've done it. We've finally devised the technology that will allow us to safely and efficiently leave Earth behind and explore our corner of the galaxy. We're still working on the intergalactic systems, but we've come across a hiccup in our plans to spread humanity away from our vulnerable home world: ourselves.
Before launching the first colonization mission, the Central Space Authority, comprised of representatives of every space-faring nation on Earth, wants to lay down a few laws to govern mankind's impact on the worlds he encounters.
A few concerns they want to address can be found here, namely the following:
- Balancing the rights of man with the rights of the new world
- Balancing the rights of man with the rights of flora/fauna of the new world
- Balancing the needs of man with the rights of the new world (aka, terraforming)
The CSA doesn't want to harm the universe as a whole or restrict man to the observation of Earth's immediate neighbors, but neither do they want to curtail man's ambition to explore the stars or ensure his species' survival.
Which single principle should the CSA focus on above all others for defining initial laws to protect both mankind and the universe without drastically limiting the ability of man to leave Earth?
Please support your decision with a brief rationale.
