India Fighting Future Tsunamis... With Trees

Trees, long known by the sannyasin of India to make ideal seat covers, also have wave-fighting properties. Good for India for thinking of an environmentally sound tsunami countermeasure. One half imagines that if the same thing had happened in, say, Oregon, the response would be a big concrete wall or something equally dumb. Of course, trees are cheap, and that's why they're doing it, but it lends credence to the idea that some environmental innovations may be more likely to come from the Third World, since First-World solutions are often too expensive for them.
