The medicines we rely on may be unintentionally affecting the natural environment around us. Evidence is mounting that modern medicines present a growing threat to ecosystems around the world. The chemicals humans ingest to stay healthy are harming fish and other animals.
Modern pharmaceuticals have revolutionised disease prevention and treatment. But after our bodies use medicines, they excrete them. Eventually, the chemicals can end up in rivers, oceans and soils.
This is a problem, because medicines designed to treat humans can also affect other species in serious ways, changing their bodies and behaviour. The chemicals can also pass through food webs and affect animals higher up the chain. Urgent action is needed to design drugs that work on humans, but don’t harm nature .
