ARTIFICIAL ESTROGENS AS CARCINOGENS & ENVIRONMENTAL /WATER POLLUTANTS
Most chemical 'contraceptives' such as many types of The Pill, The Shot, the Patch, Norplant, Depo-Provera contain artificial estrogens (female hormones) which are classed by World Health Organization (WHO) as carcinogenic compounds — they can cause cancer — https://www.physiciansforlife.org/world-health-org-declares-the-combined-oral-contraceptive-to-be-a-recognized-carcinogen-905/
More and more studies are confirming that artificial estrogens are NOT REMOVED by city water treatment plants; so estrogens continue to collect in our water supplies… they are adversely affecting some forms of fish and other wildlife…
Estrogens could have an emasculating effect on men who ingest too many of them.
Of course, these studies are NOT politically-correct; but if you search for "estrogens environment" you can find plenty of items from university studies, etc.
