We need to save Earth, and my geoengineering has just the ticket.

Replacing N2 and CO2 with H2O2 is just for starters.  However, crystal
dry CO2 isn't half bad for initially building up that lunar
atmosphere, and I'm certain that we'd get full public support for
exporting 100 million tonnes of terrestrial CO2 to the moon  (Big
Energy alone might pay at least 100 billion per million tonnes, along
with public matching funds would make it worth $200B/1e6 tonnes),
along with whatever other nasty stuff that no one wants in their back
yard, such as those most lethal elements from coal ash could bring
that export tally of revenue up to a worth of $1T/1e6 tonnes).

Imagine all the dead folks we could deposit on the moon for as little
as $10M each.  That should generate a few other atmospheric gasses.
