The trees are full of leaves, bulky and heavy laden. They clean the air, drawing in carbon dioxide and producing oxygen. I hate to think of when these trees will be gone. They may become aged and diseased. I think of them 50 years ago, how big were they then? Saplings or bigger? How old are they. What is their life expectancy? I hope they see the next century safely. Their dark green canopies giving continued shelter even as the climate heats up.
