Flushing away fishes

 

 

All of us swallow pills when we are unwell, which are excreted in our urine. But, the wastewater treatment plants don’t filter out drugs. The problem arises when people flush unused drugs down the toilet which find their way to nearby lakes or streams. Researchers found that drugs like antidepressants, which end up reaching the sea or river, affect fishes in many ways, like slowing their response to predators and their techniques of hunting prey.
