Then you realize that Earth is just a large submarine with a tiny habitable living quarters and a whole hell of a lot of passengers. There is no "away" here either:
Women's use of contraceptive pill may be linked to men's prostate cancer risk.
HealthDay (11/14, Reinberg) reported, "With the vast increase in the use of the contraceptive pill over the past 40 years, the amount of estrogen entering the water supply may be partly responsible for the increased incidence of prostate cancer around the world," according to research published in BMJ Open. Researchers looked at "data from the International Agency for Research on Cancer and the United Nations World Contraceptive Use report to identify the rates of prostate cancer and prostate cancer deaths as well as the proportion of women using contraceptive pills." The investigators "looked at some 100 countries and found that where the use of oral contraceptives was high, so was the rate of prostate cancer."
