Pharmaceutical and Chemical Contamination

Antibiotics, hormones, antidepressants, and sunscreen chemicals are now detectable in oceans worldwide, with studies showing that even 1 nanogram per liter of synthetic estrogen can feminize male fish and collapse fish populations. Over 200 million tons of pharmaceutical waste enter oceans annually, from discarded pills to sunscreen washing off swimmers, creating chronic, invisible damage that dwarfs the acute threats from mining.
