The Army and Navy divers have started the huge job of removing up to two million old tires from the ocean floor off the coast of Florida. What began with plans for the biggest artificial reef ended up an ecological problem. The entire removal process is expected to last until 2010. The Navy and Army divers are using the tire removal project as a training exercise. William Nuckols, coordinator for Coastal America, explained that the current phase of the programme has been structured to practise various salvage techniques so that they know the right people and equipment to bring when they work on this project for several months each year.
