The Great Wall of Japan

After the disaster of March 2011, the Japanese authorities decided to build a gigantic 15 meter high, 500 kilometer long, anti-tsunami wall, separating the land and the ocean. But what is the environmental and human impact of this wall? The population is divided on their opinion: should they cut the island off from the sea or stay vulnerable to tsunamis? Is there another way?

Rated 5 out of 5 by from Absolutely fascinating topic I absolutely loved watching this video. Hm, it did make me wish someone could come up with technology to create a cancellation wave for tsunamis or at least a refective wave that would reduce its damage more considerably.

Rated 5 out of 5 by from Lots of Information A 400-km long sea-wall is being built to protect Japan from tsunamis. This documentary addresses the various viewpoints of the population along Japan's north-eastern coastline regarding the efficacy of sea-walls, since earlier (smaller) sea-walls were destroyed in 2011. Many people have moved to higher ground, so the new sea-wall protects unpopulated areas. I found it very interesting to consider the pros and cons of this huge project.
