I’ve often wondered what will we kill on Mars? Can a planet be inhabitable with nothing to kill? Will it be boring because there is no killing going on? Humanity has never actually experienced no killing – is it in our DNA?
Do we need killing to feel life has meaning. Perhaps human-killing-human will become the only instinctually satisfying form of killing – so we can at least watch that on the news on Mars. I take it for granted that no matter where humanity goes, the media goes with it.
Will we take animals to Mars to breed and kill them? Actually shipping cows and sheep would be too expensive, so it would have to be some kind of frozen-fetus deal. Can you grow a cow outside the womb? Will female humans be required to act as surrogates for (small) sheep or pigs or rabbits and whatnot to get the thing going?
Are we going to transplant fertilized sheep fetuses into women who colonize Mars?
