While US and EU governments seem now to give official support for Moon mining, I wonder whether if we would mine away from the Moon same quantity we have mined on the Earth so far, would that introduce cosmological risk to Earth's conditions?
- mass of the Moon: 7.34767309 × 1022 kg
- mined mass on the Earth so far to set a scale to what mass the humanity has been able to move around so far: could be 30 trillion tonnes an upper limit?
- Moon mass extraction from where Earth's orbit either tidal forces would significantly change introducing terrestrial environmental risks: the answer to this question
In simpler words: would be there a problem with orbit dynamics/tidal forces if humanity mines 30 trillion tonnes off the Moon? (Maybe, using self-replicating robotic mining complexes it could happen in decades or in a century).
