Some scoff at earth day, some take earth day very seriously...we enjoy earth day!  I like to sit back and take a deep breath...pause for a moment and enjoy the absolute fact that I'm alive on this earth today.  All of the trees, plants, animals and people make this great world what it is and that's a beautiful thing.  So, even if you do scoff at earth day, get out there and meet some people taking earth day seriously (even if that someone is a houseplant) and have some discussions.  Make a garden, plant some trees and get to know earth, earth's nature and each other's nature.
