It was great! In the negative consequences of untreated sewage in rivers question, did u write about eutrophication?
I wrote that the amazzing algal bloom would block so much sunlight that plants would stop living cause they got no light. aerobic bacteria act and use up the oxygen creating a shortage and the fish die.
i wrote about metals like lead destroying the gills , contraceptive hormones leading to feministaion of male fish ,fish get stuck in plastics or they can get stuck in respiratory passages ,eutrofication etc .......
