According to weforum, "the world consumes 100.6 billion tonnes of materials annually."[0] 100.6 * 10^9 tonnes is 1.00610^14 kg. According to Wikipedia, the mass of the moon is 7.342×10^22 kg. If we switched our entire mining infrastructure to the moon tomorrow, including stuff like sand and gravel for construction (which would be pretty crazy) it would take us 7.298 10^8 years to consume the entire mass of the moon. It would take us 7.298 * 10^6 years to consume %1 of the moon. 7.3 million years to reduce the mass of the moon by 1% and increase the mass of the Earth some trifling percent that I don't feel like calculating right now, but you get the point. Long story short, mining the moon at our current rates of mining would do nothing to sea life, or life in general on Earth, while mining on Earth has and continues to do immeasurable damage to life on Earth.
