Aspirin is man-made. -ASA is complex organic compound, that exists in nature
Penicillin is man made. - Penicillin is a mold, that exists in nature
Bread is man-made. - The grains and yeast beg to differ
Oxygen can be created by man; is that oxygen then bad oxygen? - Last time I checked, bar any external source(ie. friendly neighborhood ice-comet), all the oxygen on this planet is all that there is, we don't make any.
uhhhh?
