You want to discuss the ethics of colonizing ROCKS. Big Floating Rocks.

To preserve the moral integrity of things that DO NOT EXIST.

Worthwhile subject.

Sure. Let us talk about the moral conundrum of my thinking disrupting quarks - how dare I. Or how about the ethical dilemma of our activities as they are currently impacting non-existent storybook characters. The moral obligations we have to figments of a schizophrenic's hallucinations.

Well, if life on Earth began spontaneously without any panspermia (directed or otherwise), I'm sure glad personally that no alien race 4 billion years ago thought it would be nice to seed this particular lifeless (at the time) floating rock on which I now live -- and thus perhaps causing me or any other human to have never existed...

...on the other hand, if we ARE here only as the result of directed panspermia, then to those aliens responsible for doing so I say:
"Thanks!"


The problem as I see it could be this:
We wouldn't seed planets that are completely "barren" of potential life-sustaining/life-producing materials. That would probably be a waste, as the life we seed will have nothing in which to "take root".

So obviously we would seed lifeless planets that have the potential for supporting life (i.e., lifeless planets possessing organic compounds and amino acids). However, those planets are the same ones that may actually spontaneously produce their own life someday. I refer again back to the lifeless Earth 4 billion years ago. Potential deliberate seeding of Earth 4 billion years ago could possibly have changed the course of ALL life on Earth as we now know it.


Having said all that, if humans someday find another planet on which to colonize, then that planet will probably already have life of some sort, although perhaps not intelligent life. Obviously, the mere presence of humans on that planet will also alter the course of that planet's indigenous life in a way that would not have occurred without human intervention.

I'm not against that -- I'm just pointing out that it will happen. By seeding planets or colonizing planets, humans WILL be changing the natural course of life (future life or existing life) on those planets.

how is it going to help us? well we could send genetically modified bacteria, mosses, lichen etc to planets or moons that we'd like to colonize ahead of us to work on creating a biosphere for us. basically terraforming planets and moons for colonisation.


as a general reply to the thread:

i just love reading all the replies of people who obviously hate humanity. the kind of people who'd really like to bottle us all up here on earth never to colonize another planet, all the while condemning their fellow man for their "messiness".


you know what the biggest hurdle after money is to making switches to more energy efficient and less polluting technology is on earth? existing infrastructure. having to refit, rebuild, alter etc.. all of the connecting parts and pieces.

moving to a new world, you can institute all of it right from the get go. i'm not saying we can't or shouldn't clean up our act here on earth, but claiming that's why we can't colonize other planets is a cop-out. we NEED to colonize, in a big way. For resources, space, science, exploration and most importantly survival of our species. Lets face it, anyone who believes humanity will survive another million years on earth is probably betting on the wrong horse. all it takes is one asteroid and the sum total of humanity's history on earth will be wiped out.

Seeding does not have to be taking a young planet and contaminating it with our own genetic material. Instead we could have robots terraform dead worlds or worlds not capable of sustaining life on their own - and making them suitable for life.

Locally speaking:

Mars - We could have robots mine ice from somewhere else in the solar system and send it to Mars. To build up an atmosphere and add water. Sure it could take hundreds of years, but if robots are doing it so what. In the meantime we could build giant green houses to start establishing life there. And seed some of them with endangered species. For our own needs we usually only care about plant life, so if some of the other players for a sustainable ecosystem are from endangered species - so what. Its good for them, and could make up for a tiny fraction of our destruction of life on this planet.

Venus - We could have robots create a "thick" blanket of satellites to block out most of the Sun and start cooling it down. At the same time they could convert solar energy and eventually beam it down to energy collector stations. Then ... who knows ... but eventually establish life there as well. We might have to start with artificial shelters again.

Moon - We could have robots simultaneously create large subterranean caverns [to minimize the effects of radiation] for life, while also exploring for useful minerals. Then either - or both - feed light back in via solar cells that convert the electricity back to life, or transport light via optic cables. Again we could use some endangered species for some of the key players in a sustainable ecosystem. Just think of the moon base that could be built at the same time. Well, would actually have to be built ahead of time.

Also, think of the knowledge to be gained. Isn't that what humanity is about - Knowledge.

Knowledge is an excellent way for us to get our way. Knowledge is a tool to survive better.

A plant can undergo many changes derived through time through selection, through slow adaptations, or due to severe curtailing of viable seeds due to some climatic effect.

This is pretty understandable to people.

Our species has undergone several near extinction events, and in the process have adapted by getting smarter to take advantage of a World where the climate has changed severely over and over in the short period of time that we have been a species.


The biosphere - the living things that interact to make up the biological environment of the living on the exterior of this rock - the layer of "alive" sitting on this big rock - it has undergone the same process that our species has. The biosphere has been knocked back and recreated from scraps over and over.

The biosphere has adapted.

What the biosphere hasn't done yet is found a way to "seed" itself.

It cannot reproduce itself elsewhere. It is doomed to eventual destruction, some point at which it cannot recover. Some event that doesn't leave enough of its components around to reboot the living shell.

But the biosphere has found a way to seed itself.

By having a component that CAN get off the rock and take a sampling of it with them.

That's us.

Ever other adaptation has failed so far, in taking too long to come to fruition. They niched too well. They were too slow in the temperate climate, and got wiped out in the same events that cause the biosphere problems.

The consistent climate changes that have almost annihilated us over and over are the impetitious that drove us to become more intelligent and adaptable. We are part of that biosphere.

Anything we do will require anything from a microcosm of the biosphere to a functional copy of it.

We are not a VIRUS. We are a SEED. We are currently the only possible long term solution our planet, and indeed all life as we know it, has to survive in the Universe.

Well let me see. we have seeded Australia with the cane toad and poisoned much of the wildlife. Seeded the nile perch in Several african lakes. we have seeded waterhyacinth in south american canals and blocked them..


Actually this seems like a stupid idea. Besides how do we know where life exists and the complexed web of interactions.

Why don't we study life instead?

We do not know sufficient about space ecosystems. We thought that we knew about terrestrial ecosystems and seeded them with other lifeforms and made a big mess. We now have Iguanas and 12 ft pythons in Florida from a simialr foolhardy attitude.

There is no ecosystem on a place that houses only lichen if lucky.
