Tsunami Wall

In class we watched a short video about how Japan is building large sea walls along their ocean to help in case another tsunami occurs. The walls are extremely high and will act as a last ditch effort to save people from a tsunami. A lot of locals are very upset that they are putting these walls up because they feel that it is separating them from the ocean. Many of the towns that the wall is going near depend on the ocean as a way of life. They depend on it for tourism as well as bringing in business to their shops. The walls can also act as a problem for local ecosystems. I personally feel that they should invest more money in tsunami research and invest money in ways to detect the tsunamis sooner. Putting up a wall seems very drastic and I feel there are more ways to deal with this problem than just putting up a massive wall.
