Reading Seveneves by Neal Stephenson may have inspired this thought, but how much change in the Moon's mass by shipping materials to Mars or Earth from the Moon would cause enough change in the Moon's orbit to affect Earth's tidal cycles, and other dependent phenomenon?

So if we moved the entire crust of earth to the moon it would barely touch the orbital revolution of the moon unless we also transferred energy along with those 28 quadrillion metric tons of mass.
