Created by the Harvard Smithsonian Center for Astrophysics in association with the Harvard University Center for the Environment, this 13-part program includes an overview of the Earth's systems along with an exploration of the effects that human activities have on these systems. Each program contains interviews with scientists and other experts, and the program titles include Ecosystems, Human Population Dynamics, and Water Resources. The site also features videos, interactive lab exercises, additional visuals, an online textbook for each topic, and a helpful glossary of terms that runs from "acid rain" to "zoozanthellae." Each program is well-written and executed, and anyone looking for a bit of a refresher on these topics will find this resource most interesting.
