Sustaining life in space

Everything we are and everything we have ever touched – seawater, sunflowers, snowflakes – is made of atoms that once were drift/adrift (1) among the stars. These atoms are found on adjacent/neighboring (2) planets as well, so in principle it should be possible to rearrange/reform (3) them in such a way that Mars, say, could be given a breathable/breathtaking (4) atmosphere and become a family/familiar (5) place with thunderclouds and cornfields.

If we take care of our own planet, we might in good faith endeavor/encounter (9) to seed barren planets with earthly life. If, instead, we reform/resort (10) to terraforming as a means of escaping ecological disaster at home, that bad faith effort/afford (11) will almost certainly be doomed. Spaceflight cannot solve/resolve (12) the population problem – there will never be enough spaceships for that – and in any event/occasion (13) there’s little point in colonizing another world just to muck it up. The question, badly put, is whether our species is good enough to deserve/reserve (14) a new world.
