Oxygen: Breath of Life: Tim Parrott

"Without oxygen, virtually every plant and animal on the planet would die. The first part of this 6-week course looks at a variety of plants, the second at animals and how the two great Kingdoms have evolved to pass this substance back and forth. Most of us know that plants are at the base of the food chain, but we're apt to forget that they also give us our oxygen. "
