...A Seed Was Planted

But as we researched the state of the planet, our dreams began to fade. We learned that global warming, urban sprawl and the pollution and depletion of our natural resources are no longer localized problems. We became convinced that unless consumption patterns change, our children's Earth will be but a shadow of the world we now know.
