Impact on Humans

Stone is used in tons of different ways which impact us humans everyday. Cars, planes, boats, trains, bus, bike, these all require different rocks and minerals. If we didn't have these materials we wouldn't have cures to different diseases, we wouldn't have fast transportation, no clothes would be available. We'd practically be cavemen just a little worse.
