Name: Charles, Stockport.
Qualification: Chemistry A level
Answer: It doesn’t. You can’t create or destroy matter other than with a nuclear reaction. So everything else is chemical reaction such as humans and animals that are made out of carbon, etc. This had to come from somewhere, so the earths the overall mass remains the same.
