>>12007384First off, Mars will never be terraformed. It’s a fools errand and a massive waste of the potential of the red planet. Mars is going to be colonized as a forge world where we outsource all of our high pollution industrial processes and probably a good portion of our energy production. Melt down a nuclear reactor on Mars? Who cares, fill in the hole and build another one a couple miles away. Got toxic exhaust? Dump it straight to atmosphere. Sludge? Lol just put it in a pit. Those precious metal asteroids can be slammed into the planet and all the good bits scooped up. You could argue that the moon would be suitable for this purpose but NIMBYs look at the moon. No one can really “see” Mars from earth so no one will care.
Now, back on earth we are free to “terraform” all the little normally inhospitable places like the oceans and desert and convert them into gardens. The whole of earth would be purposefully changed into an agricultural eden for the sole purpose of habitation and sustainment of mankind.
