We need trees, because they produce oxygen and help the environment in so many ways. That's why I have started planting trees. Every year, I go into the hills of Marin and plant saplings. It's my way of keeping the Circle of Life intact. Plus, it's good karma. I suggest you give it a try--get out there and get it done, because when you think about the world and what we're doing to it--you HAVE to get it done. Locate a good tree nursery, talk to their experts and plant a few trees per year. You'll be doing a great thing, because we need trees now more than ever!
