<ul><li>More than 150 miles of National Trust coastline in Devon and Cornwall could be affected by rising tides during the coming decades. </li></ul>Among the areas which will come under attack are Woo Lacombe Beach in North Devon, and Man Sands in the south of the county.
<ul><li>Mass migration to coastal areas has caused beaches to become subject to pressures from sources such as industrial development, urban expansion, exploitation of marine resources and tourism. And with more than half the world’s population living within 60km of a coastline, the environmental damage poses a serious threat. </li></ul>
The Needles These needles are stacks and stumps if you look at the bottom of them they are different colour this is because of erosion.
The needles continued. <ul><li>The Needles are the western most point of the Isle of Wight and are a series of chalk stacks which protrude into the see at the end of which is a lighthouse. Nearby is Alum Bay, which is home of the famous coloured sand but is has a rather commercialised 'pleasure park'. The is a chairlift from the top of the cliff to the beach. The sea around the Needles was notorious for shipwrecks. The first lighthouse was built in 1785 on top of the downs, the current one during from the 1850's. A helicopter pad was added in the 1990's and the lighthouse subsequently became automated and unmanned. </li></ul>
This has happened because sea water has over time eroded away the rock away which has made the house fall into the sea.
