I love Earth Day.  Granted, I try to do something good every day for the environment.  Tomorrow (4/22) I'll try to be less lazy and go pick-up some trash lying on the side of the highway.  I have a few little trees that need planting, too.  A pear tree, an apple tree, and one other one -- can't tell what it is though.  I'll have to wait for it to grow up and then I'll know.
It's good to know that Earth Day truly is known and celebrated worldwide.
