Dolphins, symbols of intelligence and grace, are being poisoned by plastic. In a shocking discovery, researchers have found that bottlenose dolphins are exhaling microplastics. Tiny fragments of plastic, invisible to the naked eye, are making their way into dolphins' lungs¹. This means that dolphins, which rely on their large lung capacity for deep dives, are increasingly vulnerable to the microplastic particles polluting our oceans and air².

For the first time, scientists have detected microplastics in the breath of these marine mammals, collected from dolphins living in the waters of Florida and Louisiana³. These particles, similar to those found in human lungs, come from everyday materials like clothing fibers and plastic packaging⁴. When ocean waves stir up plastic debris, it enters the air as microplastics, which dolphins — and possibly humans — then breathe in⁵.

This contamination doesn’t just affect dolphins. It’s a warning sign for us all. Dolphins are sentinel species, meaning their health reflects the state of their environment, and by extension, ours⁶. The microplastics they inhale contain harmful chemicals that have been linked to inflammation, tissue damage, and long-term health problems in both animals and humans³.

The Invisible Threat of Microplastics

Microplastics — pieces of plastic smaller than 5 millimeters — are now everywhere, from the deepest parts of the ocean to remote mountaintops. They come from the breakdown of larger plastics, entering the environment through improper waste disposal, synthetic clothing, and single-use plastics¹. Each year, millions of tons of plastic waste enter the ocean, breaking down into tiny particles that pollute the water, the air, and now, as we’ve learned, the lungs of dolphins¹.

What’s more alarming is that dolphins living in both rural and urban waters are exhaling microplastics. This shows that no place is safe from this pollution⁵. In densely populated areas, the problem is worse, but microplastics have been found even in areas far from human activity, highlighting the pervasive reach of this environmental crisis⁶.

Why We Need Urgent Action

Every breath a dolphin takes is a reminder of how our choices impact the world around us. But the situation is not hopeless. If we act now, we can reduce the amount of plastic entering the oceans, cutting down on the microplastics poisoning marine life. Our daily choices — from the materials we use to the products we buy — can reduce the flow of plastic waste that ends up in the air and water.

Reducing microplastics isn’t just about saving dolphins; it’s about protecting the entire marine ecosystem and human health. Dolphins are our warning system, showing us how far-reaching the plastic pollution problem has become. It’s up to us to turn the tide and protect these creatures — and ourselves — from further harm.

Take Action to Save Dolphins

Dolphins are literally breathing in the pollution we’ve created. We cannot stand by while our oceans, air, and marine life are suffocated by plastic. It’s time to take responsibility and commit to changing our habits. Reducing microplastic pollution starts with each of us.

Join us in demanding action to protect dolphins and our planet. Sign the petition now and pledge to reduce plastic waste in your own life. Every signature counts toward a future where dolphins can breathe clean air and swim in plastic-free oceans.
