The Biosphere

Global warming, ozone depletion and acid rain all make headlines and the evening news. In order to understand these and other global environmental problems, students need to understand what biologists call the biosphere.

Part 1. A Brief History of the Biosphere. How did the biosphere come to be? Traces the history of four billion years of the growth of the atmosphere and of changing life on planet earth.

Part 2. The Biosphere Today. Gives the student a clear, dramatic picture of the scientific concepts needed to understand the biosphere today.

Ecosystems

What is ecology? How can it help us understand the world we live in? An up-to-date program ideal for life sciences and environmental studies.

Part 1. From Nature Study to Ecology. The naturalist tradition of Henry David Thoreau is contrasted with the hard science tradition of modern quantitative ecology.

Part 2. The Web of Life. Carefully outlines concepts used by ecologists to study ecosystems today. Program includes a look at how human values play key roles in environmental choices.
