Trees are truly remarkable in that as the roots grow beneath the earth, they continue to branch out all over the planet, straight through the middle! These branches beneath the earth pop up at various locations around the globe to form what look like new trees. DNA testing has shown that there may be as little as 17 to 25 actual separate trees on the entire planet, and there is now mounting evidence that if not for the roots of these great trees, the earth would simply crumble away into space.
