Two questions I have, but haven’t had the time to do the research:
1. Based on the law that mass can neither be created nor destroyed; if we send too much mass from the earth outside the gravitational pull of the earth, will that cause the earth’s orbit around the sun to change? If that’s true what effects will that have on the earth? Conversely, if too much mass from an asteroid or the like adds itself to the earth, will that affect our orbit? (Actually, I doubt there is any way to know how much mass is too much unless it actually happens.)
2. Since humans are mostly made up of water, doesn’t it follow that as the population grows the amount of water decreases regardless of the weather conditions and our consumption (ie: droughts)?
