Technological advancement does not equal a greater sense of ethics and morals. We're close to ass [censored] this planet beyond repair, and the solution is relocation? Like that'll change our current behavior... We already know what to do to improve the conditions of this earth, but we don't do it.
Relocation my ass. We'll just become a planetary-consuming horde of locust.
Ethics and morals are completely subjective and determined by the will of the majority. You can throw around those terms like they hold any objective value, but that doesn't change the fact that if slavery somehow became accepted by 90% of the world population tomorrow, peoples sense of ethics and morals would adjust accordingly.
Your seething misanthropy makes me wonder why you haven't killed yourself yet. You might see yourself as a cut above "those other, awful, greedy humans" and instead stand as a symbol of goodness and morality. That would be egotistical and awfully self-righteous. Unless you contend that you're just like the rest of us; in that case I refer to my original offer.
I am a speciesist. That much should be obvious by now. You and I could have nothing in common other than our human genome, but that alone sets us apart from every other species in this universe, and that kinship means more to me than political boundaries and morality, which is why I refer to myself as a human, above all else. For all our mistakes and imperfections, we are still capable of achieving impossible things as a species.
This probably won't have as much an effect on you as it does me, but the http://www.youtube.com/watch?v=oY59wZdCDo0 remains a major source of inspiration that humans can do anything they set their minds to, both good and bad.
