Tetrapods on Japanese shores

Among the Japanese coastal landscape can often find a lot of designs of tetrapods - special protective structures that are to help prevent coastal erosion. According to some estimates, more than half of the 35,000-kilometer coastline of Japan are covered with these huge concrete structures. Critics of this method for protecting coasts say that the way the Japanese government simply wanted to support the construction industry of the country and themselves tetrapods only create additional danger to swimmers, surfers and boaters and actually accelerate the erosion of the coast, destroying the natural processes that form the coastal environment. But still, one can not ignore these concrete piles some futuristic aesthetic beauty.
