- 6Millions of tyres dumped for artificial reef became an ocean disaster▼On a site the size of 27 football fields, 2 million of these were dropped in the ocean to create an artificial reef – instead, it became a disaster
Around two million tyres were dropped onto the seabed on a site the size of 27 football fields in an attempt to create an artificial reef. Instead of attracting marine life, the project became an environmental disaster, as the tyres failed to form a reef, scattered across the ocean floor, and leached toxins. The scheme is now widely cited as a cautionary tale about large-scale marine engineering projects.
