My neighbor in Boulder grows and gives away trees for a hobby - every June, anyone can go to her house and pick up a free tree. Her purpose is to add oxygen to the atmosphere to help balance growing carbon emissions. An excellent example of improving your environment. "The idea that one has a share in the planet and that one can and should help care for it may seem very large and, to some, quite beyond reality. But today what happens on the other side of the world, even so far away, can effect what happens in your own home." I picked up a Golden Current. Thanks, Elizabeth!
