I didn't say we wouldn't make use of other planets as places to live, but I believe we should respect the native life that almost certainly exists on some planets. I'm glad we're taking this attitude towards Mars at the moment, exploring but being careful not to bring Earth's lifeforms over to Mars to breed. In any case, my question still stands, what do you/we hope to gain from infinite economic growth?
