I don't think we have much of a choice. It may save our species and Earth to colonize places without physical life for spillover population. We'll need to figure out how to decrease our impact on Earth in parallel.Insanity. We can't even manage our own planet. We don't belong on other worlds until we can live on our own without destroying it.
That will never happen. Who could decide when all earth's people are living together amicably. Get over it and get on with the exploration and habitation. Our species needs to learn but sitting here (on earth) waiting for things to quiet down would mean never getting off the earth, never exploring other planets and never developing our minds. Stagnation is the alternative you are offering. I would not become much upset if we managed accidentally to destroy a herd of martian bacteria but it is more likely they would destroy the explorer. After all, they are the adapted ones.
Mankind has no shortage of flaws, but an opportunity to create something more adaptable makes a logical starting point when looking at the long term picture of survival and growth.people can be so so so stupid. We can't get together to fix our challenges here on earth so we distract ourselves by wasting time and money on some ridiculous star wars fantasy
I hope you realize, that DNA and genetic engineering is not just medicine, but it has even more to do with biology! And also human genetics IS biology!"Genetic engineering and other advanced technologies "may need to come into play if people want to live and work and thrive, and establish their family, and stay on Mars," Kennda Lynch, an astrobiologist and geomicrobiologist at the Lunar and Planetary Institute in Houston"
An astrobiologist/geomicrobiologist knows exactly ZERO about medicine and human genetics. LOL!
