Question: What viable solutions can you think of to solve the problem of coastal erosion (as over thousands of years surely all of the land will end up as a sea bed)?

Should we ‘solve’ erosion? Long shore drift is only a problem if we want to keep one area! Perhaps we should move along the coast with it! I think trying to fight nature is always a losing battle.

I don’t think we can solve erosion. It is a natural part of the earth and as Laura said, we are best just adapting to it.
However, tactics for preventing erosion in the future have been under investigation by scientists and geologists all over the world. Today, the most effective method for erosion prevention is soil surface cover. In this method, some type of permeable material, left over crop residue for example, covers the soil surface, which includes rock and sediment debris. This decreases the deteriorating capabilities of the impact from rain, animals, machinery, or any other type of eroding agent. As a result, surface runoff is controlled which helps eliminate the transportation of eroded particles elsewhere, thus slowing the process of erosion as a whole.

Giving way to the sea will displace thousands of people as well as destroying infrastructure, the costs and effort of repeatedly rebuilding would be huge in the long term not to mention the emotional effect on many individuals.

A new found method is buryong Christmas trees in the beach. It makes less sand and other materials get taken out, making more dunes and less coastal erosion.

Burying trees on coasts is an admirable idea but it is not a viable option for the whole coastline as it would have no effect where cliffs are considered and it would merely slow coastal erosion and not prevent it around beaches.
