Plastic pollution is one of the most pressing threats to our oceans today. In this episode, we explore how microplastics—tiny fragments of plastic waste—make their way into tropical marine ecosystems and cause lasting damage. Whether it’s through broken-down consumer products or fishing gear, plastic pollution infiltrates ocean habitats and harms marine life in ways we’re just beginning to understand.

Coral reefs, often called the rainforests of the sea, are especially vulnerable to plastic pollution. These vital ecosystems support biodiversity, protect coastlines, and sustain livelihoods. Dr. Lisa Rodrigues, a professor at Villanova University, shares her research on how microplastics impact coral health, disrupt growth, and even contribute to disease in reef systems. Plastics can also alter water quality and affect the delicate balance that coral reefs depend on to thrive.

Marine debris isn’t just unsightly—it’s a serious ecological problem. From lionfish to tiny plankton, organisms across the food chain are ingesting plastics or suffering from habitat degradation. Dr. Rodrigues explains how even pristine-looking beaches can hide layers of microplastics beneath the surface. We also discuss how citizen science, beach cleanups, and community involvement play key roles in fighting plastic waste in coastal areas.

Ocean conservation efforts must include tackling plastic pollution at its source. In this episode, we talk about the role of environmental policy, education, and innovation in reducing marine plastic waste. Whether you’re an activist, student, diver, or beach lover, there are actionable ways you can help protect coral reefs and reduce the plastic footprint in our oceans.
