For me, Earth Day is rife with mixed emotions. This is our only home and it's beautiful, diverse, and delicate. I'm in awe of what this unique blue marble gives us every day. But we treat Earth like she has infinite resources, free for the taking... and taking... and taking. How can people treat their only home with such utter disregard and disrespect? Thank you, R.R., for a beautiful tribute to our mother planet.
