Since the Industrial Revolution sparked the widespread burning of fossil fuels, scientists have concerned themselves with the climatic effects of carbon dioxide. This program spotlights milestones in the history of that research as it seeks to understand humankind's impact on Earth's atmosphere. The greenhouse effect, global warming, ozone depletion, the Keeling Curve, the Atlantic Conveyor Theory, and other key concepts are illustrated through the...

Description
This program discusses how the chemical alteration of oncogenes in human cells causes the growth of cancerous tumors. Toxic substances, radiation, viruses, and inherited genetic defects are examined as factors causing such alteration. The mechanisms by which the altered forms overrule normal cell regulation are illustrated through microscope views and computer animation. Specific information is provided on cell cycle, cell division, growth factors,...
