Every year, an alarming number of golf balls are lost in oceans, rivers, and lakes. While small, these forgotten balls are far from harmless. Each one is packed with synthetic materials—plastics, rubber, and metal additives—that persist for centuries, leaching toxins as they break down into harmful microplastics. Our waters are filling with these pollutants, posing a critical threat to marine life and the health of our ecosystems¹.

Toxic Plastic in the Food Chain

Once in the water, a golf ball slowly degrades. Currents and waves grind it down, releasing toxic microplastics that spread across the seafloor. These particles are often mistaken for food by fish, birds, and even endangered species like sea otters². As these animals ingest plastic particles, the toxins enter their bodies, compromising their health and even risking their survival. Disturbingly, these microplastics can travel up the food chain, ultimately reaching humans³.

Millions of Golf Balls Polluting Our Waters

Each year, an estimated 300 million golf balls are lost in the United States alone⁴. In coastal areas, where courses are set beside picturesque ocean views, these stray balls end up in the water by the thousands. At California’s Pebble Beach, researchers discovered over 50,000 golf balls on the ocean floor—just one course’s pollution footprint⁵. With more than 30,000 golf courses worldwide, the cumulative impact is vast.

Golf Courses Can Make a Difference

Coastal and riverside golf courses can play a crucial role in preventing further damage. By implementing cleanup efforts to retrieve balls that have already settled on the ocean floor, and by installing net barriers around water hazards to stop more from entering, golf courses can help reduce this overlooked source of plastic pollution⁶.

Take a Stand for Our Oceans

Golf courses can be both sustainable and scenic, and players and nature enthusiasts alike deserve environments that support wildlife and clean water. Sign our petition calling on Pebble Beach Company and other coastal golf courses to take accountability, stop adding to the problem, and start actively protecting our waters.
