Your point is taken and is accurate. The application seems to apply within limited, unique biological environments. The world's plans for the human settlement of extraterrestrial places would be one of those unique environments, shipboard and in situ. Back on Earth; My opinion: Pandemic, epidemic, localized diseases will occur due to the unforeseen/untoward effects of Evolution, and our actions/reactions. As for government solutions; And yes I'm highly cynical .... "DON'T TRUST THE GOVERNMENT(S) to be altruistic, knowledgeable, bias free, and farsighted". Basically, politics is akin to a three ring Big Top Circus being directed from the Monkey House. ..... H.L. Mencken wryly opined. Luckily, Evolution and random chance have produced some smart monkeys. It's those who seem to develop the insight and make the correct decisions.
