The Osbourne Reef is an artificial reef created in the 1970s off the coast of Fort Lauderdale, Florida. It was constructed using concrete jacks and over 2 millions tired. The ambitious project was intended to create a new habitat for marine life, but it was ultimately a disaster, doing much more harm then good. Little marine life attached itself to the tires and many were displaced by currents and storms, often washing up on nearby beaches. Many tires are now scattered on health reefs causing damage to coral and fish population.

A number of clean up efforts have been started over the years, with close to 100,000 tired being removed.
