Microplastic Pollution Can Fuel Rise In Antibiotic Resistance: Studies

"Plastic pollution and drug-resistant infections are usually regarded as separate global crises. But emerging research suggests links between them: Microplastic particles in the environment are colonized by bacteria, and those bacteria develop antibiotic resistance at an unprecedented rate."

"Plastic pollution is among the gravest environmental crises facing humanity. Plastic production since 1950 has exceeded 8,300 million metric tons, with most plastic waste ending up in the environment, affecting wildlife, ecosystem functionality, and human health.

Simultaneously, the ability of disease-causing bacteria to withstand one or more antibiotics (known as antimicrobial resistance, or AMR) has surged to become a public health emergency now accounting for around 5 million deaths worldwide annually.

“AMR is an existential human threat,” says Tim Walsh, a professor at the University of Oxford and director of biology at the U.K.’s Ineos Oxford Institute of Antimicrobial Research, who spoke to Mongabay via video call. “It will kill more people [each year] than TB, HIV and malaria, and if unchallenged could eclipse cancer as the biggest killer.”"
