The Earth is an amazing place. It cycles through the seasons like a giant clock. Like a heartbeat, the tides ebb and flow, summers turn to fall. It's an endless rhythm of life. The great thing about the earth is that it renews and SUSTAINS itself throughout the cycles--if we let it. But humans are now consuming so much of the earth's resources that these cycles of renewal are having a hard time keeping up. There is no way to overestimate the importance of your contribution to help sustain life on Planet Earth. Whether it is in the sciences of protecting our soil, or replanting our forests or in moving and protecting our water resource, the planet will need our help. With your interest in the green sciences, it will help insure that we stay green for generations to come. .
