In India, the growing living bridges

In northeast India, in one of the wettest places on earth, do not build bridges, they grow themselves. The trick is that in that area growing rubber tree view with an incredibly strong root system. The roots of this tree have a certain feature - they grow out. In order to give the correct direction of roots, used thin trunks of walnut - the roots entwine them and "crawl" on the other side of the river, where they grow into the soil, forming a bridge. But to complete the formation of the bridge will be a long time - 10-15 years. Then it will be possible for him to go, he will bear the weight of more than fifty people, and live about five hundred years.
