$this->bbcode_second_pass_quote('pstarr', 'T')his space travel meme is just the flip side of the doomer meme. Both are childish cop outs. Adolescent fantasy that frees it's proponents from actually working to fix things.
Kaiser you claim to be a scientist. How would you propose we colonize the solar system? What is the fuel? After all, this is a fuel web site.
No, as a point of fact I do NOT claim to be a "Scientist", nor do I worship that peculiar tribe of priests in white lab coats. I am an Engineer, I work for a living.
What an Engineer does is combine known principles to achieve a new gadget, some of which have never existed before. We don't do basic research, we audit each other's work to determine all the clever tricks, and publish in the trade journals when we have a neat new trick of our own.
But I have the love of an amateur for space travel and the love of an aficionado for my favorite form of literature for over 5 decades, which is Science Fiction. I continuously track the differences between the reality of present tech and the unreality of fiction. The current film
Gravity for example is not really SF, it is a present day drama set in space - the only fictional part being the rather unlikely plot, it all being technology available two decades ago.
In this present thread, from the viewpoint of the afore-mentioned ecologist, there is no happy ending if the ecology of the world is damaged or destroyed. My point of view is different, because I am happy enough if our species survives. It matters not to me that the planet will heal itself and evolve new life on a geological time scale, because I serve humanity and have no especial respect for the planet, and don't place the welfare of the planet above that of humans.
A century ago, had we understood our eventual fate and limited our population to the sustainable limit, I would be properly regarded as a villian, because of my profession and the fact that I serve my species . But that train has already left the station. Understand that the overpopulation of the species has already happened. There is no going back. The mere existence of 7.3 billion people, all eating/drinking/breathing/reproducing, is killing the planet. With our knowledge of Science and Medicine, we are unlikely to succumb to plagues, environmental degradation, global warming, Ice Ages, or any fate we are familiar with, including hydrocarbon exhaustion. In our numbers and with our knowledge, we are going to be the last species on Earth - at least of the higher animals.
There is a more than even chance that we can build ourselves another home (or homes) and even use such to preserve the diversity of life on our home planet - or failing in that, enough food species to survive, and enough DNA samples to engineer any species required.
Like I said before, you either believe in technology, or you don't. Those that do not understand it, fear it. Those of us who are the masters of technology simply regard it as a tool. Men like me will either save humanity, or die trying. That's the way things work, there is not even any debate over this - of course we will try to survive.
There is no magical "Earth Mother", Gaia is a myth. The Earth is a residence, we are the tenants, and we have already destroyed the place, damaged it beyond repair, and beyond redemption. It is decidedly inconvenient, but we have to move - the alternative being to lay down and die - as if we were an old, sick dog who wonders away from home, and lays down to die in a hole in the ground.
But if you KNOW of a way to reduce the global population to a sustainable limit, without further damage to the globe, and to convince women that they must be content with two children, then we can talk. We will still be going into space, understand, but having a Plan B is also a good thing.
Like I said before, it is so ironic that the finest thoughts of religious figures like the Buddha and Christ - that we love and cherish and aid one another - are at the root of the Earth's destruction. I now elaborate on that theme and note that a human woman's desire to have children plural is another element that sealed our doom. It seems sort of unlikely that 9/10ths of the present world population would report to composting plants and ask to be shot and composted into plant nutrients, but that is the bare bones description of a scenario that might "save the planet" - which is incorrect terminology for "saving the present ecology". Such a scenario seems a lot less likely than space colonies to me.
