Microplastics in human tissues prompt scientists to call for action

Harvard T.H. Chan researchers said JAMA evidence shows microplastics in lungs, brain, liver, ovaries, placentas and meconium, with Hawaiian placenta detection rising from 60% in 2006 to 100% in 2021.
They warned particles inhaled or ingested can persist in tissues, carry pollutants and may disrupt hormones, pregnancy, placental function and child health, though causation remains unproven.
The scientists urged standardised measurement, more reproductive-health research, safer plastic alternatives and international efforts to curb plastic production, projected to rise another 70% by 2040.

With microplastics now in every human placenta tested, what is the impact on our children’s long-term health and brain development?

As plastic production is set to triple, is the global health crisis it's creating already past the point of no return?
