Nicely stated, avaserfi!
I worry though about the very technology you suggest may save us. It may only be a short-term fix. "Think Tanks" and men of wisdom have long debated the
final, global destiny of any grouping of human-type lifeforms. It was an important issue in the debate over extra-terrestrial life...namely, can a civilization actually survive its own technology and proceed to advance to interstellar travel. Because of global environmental stresses, advanced destructive capabilities, and psycho-social-cultural conflicts, the answer was almost unanymously "NO".
Sorry to be so negative here. It must come with old age.
