Summary: Too much small trees in the forest can be a cause of natural forest fire. They are considered to be useless and unprofitable, so loggers hardly touch them. However, non-profit groups are cutting the small-diameter trees down for twice-fold benefits. First, it can reduce the possibility of natural bush fires. Second, by using the cut-down trees, community volunteer workers can build a wooden house for the elderly in the local areas. The type of house shown in the video is called Hogans.
Opinion: I think the non-profit organizations are doing the most necessary and valuable job for both the forest and the people.
