Angebote / Angebote:
Ted Merrill, a lifelong physician and ecologist, offers the Eco-jar as a working model of Planet Earth. An Eco-jar is a sealed, air-tight container, mostly full of water but also containing mud, sand, rocks, plants, and tiny creatures. You can easily make one by following Ted's simple instructions, and once you begin to think of our Earth as a huge Eco-jar, you'll understand how the lessons Ted shares apply to every aspect of human endeavor.
