Microplastics: a threat we can't ignore

Microplastics are invading our bodies, from the air we breathe to the food we eat, sparking growing concerns about their potential health risks.

Sanjay Gupta reports for CNN.

In short:

• Microplastics, tiny plastic particles from everyday products, have been found in organs, blood and even the placenta, raising alarm over their health effects.
• These particles carry harmful chemicals like phthalates and PFAS, which disrupt hormones and may contribute to diseases such as heart conditions, cognitive deficits and cancer.
• Simple lifestyle changes, like avoiding microwaving plastic containers and choosing stainless steel or glass, can significantly reduce exposure.

Key quote:

“It’s so pervasive because there’s so many ways we don’t think something’s plastic, but we realize it actually is.”

— Dr. Leonardo Trasande, Director of Environmental Pediatrics, NYU School of Medicine

Why this matters:

The health implications are staggering, but the solutions often feel out of reach. Avoid plastic altogether? Good luck in a world practically built on it. But experts like Dr. Leonardo Trasande are pointing to small, practical changes as ways to limit the damage. Meanwhile, the bigger battle looms: curbing plastic production before these particles saturate every inch of the planet—and our bodies. Read more: Microplastics in farm soils: A growing concern.
