Humans aren't the only thing we should be considering. Collapse of a fish population after exposure to a synthetic estrogen "We conducted a 7-year, whole-lake experiment at the Experimental Lakes Area (ELA) in northwestern Ontario, Canada, and showed that chronic exposure of fathead minnow (Pimephales promelas) to low concentrations (5–6 ng·L−1) of the potent 17α-ethynylestradiol led to feminization of males through the production of vitellogenin mRNA and protein, impacts on gonadal development as evidenced by intersex in males and altered oogenesis in females, and, ultimately, a near extinction of this species from the lake." https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1874224/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1874224/
