A review of 20 years of research highlights the global spread of microplastics and their potential risks to human health and the environment.
Joseph Winters reports for Grist.
In short:
- Microplastics, first identified in 2004, have been found across ecosystems and within human bodies.
- Main sources include breakdowns of larger plastic debris, as well as tires, paints and synthetic textiles.
- Scientists warn that without action, microplastic pollution could cause irreversible environmental harm.
Key quote:
“It’s now pretty clear that this stuff is everywhere.”
— Richard Thompson, professor of marine biology, University of Plymouth
Why this matters:
Microplastics have permeated air, water and food systems, posing potential health risks. Reducing plastic production and waste could help prevent further damage to ecosystems and human health.
