Humans are masters of destruction, aren't we? If we can create tech that can make trees grow as fast as they have been cut in this video, now that will be something to be truly proud of.They should use these in California's forests to create fire breaks and roads for firefighting equipment. It might save more trees in the long run, while generating less greenhouse gasses than controlled burns. Just an idea.I personally like the traditional way of felling trees but this way is cool, gets the job done fast and effective
