Over the past ten years oil spills have polluted the seas surrounding Britain. The tankers spill oil onto the coast and this harms many forms of wildlife. Environmentalists say that they need a lot of volunteers if they are to minimise the damage.

The government also hopes that they can prevent such incidents by building more lighthouses along the coastline.
