We may not always understand or discover why things happen the way they do, but there really is a reason for everything… and yes, even the falling of a leaf carries one. I never realized how much grace and beauty were involved in the process until I read this.

“Professor: Have you ever wondered why some trees shed their leaves during the winter? This occurs for many reasons, but the main reason trees do this is to protect themselves.
You know, most tress that lose their leaves are in cold climates. During the long, cold winters, the air in these places becomes very dry. This causes the leaves of trees also to become dry. To keep the leaves alive, the trees have to give them a lot of moisture. The problem with this is that the trees could lose too much moisture and die. So instead of giving moisture to the leaves, the trees keep the moisture inside… They keep it in their trunks and branches. After a while, the leaves start to die. As the leaves die, they fall to ground around the trees. When this happens, the leaves actually help the trees survive. How, you may ask? Well, the leaves form a protective layer around the roots of the trees. This allows the roots to stay warm. So, by losing their leaves, the trees are able to live through the winter.”
