Sunken German tanker can cause ecological disaster

It's a disaster waiting to happen and it's been wating for more than 50 years. The wreckage of an old German tanker, that's been lying on the seabed of the Baltic for over half a century, is still full of fuel. Scientists are warning that, if it leaks, it could cause an ecological disaster. The oil could make it onto the beaches of the region and harm the environment. They say action must be taken now.
