(Episodes order to be confirmed) - Is the human population going to outstrip the earth's food supply? This is the central question in this provocative new two-hour special. Side effects of recent food surpluses include environmental problems such as soil erosion, salinization and chemical pollution. Food or Famine looks at projects in North America, Chile, Indonesia, Africa and India that are participating in a worldwide movement to return to agricultural methods based on sound ecological principles. But as the world population continues to increase, new crops with higher yields will have to be developed. This special also examines the worldwide imbalance between food consumption and production.

We look at autism, a mysterious disorder that impedes normal development in humans and looks at new developments in its treatment. It was once believed that autism was caused by remote, cold parents; most often the mother was blamed. Today, autism is recognized as a partly genetic biological disorder, but its cause is still a mystery. The Child Who Couldn't Play examines the latest research on autism. At the Princeton Child Development Institute, the results of the science-based approach to autism attract professionals from around the world. Of the children under the age of five who are treated, over half progress to regular school classrooms. Winner of the Chris Award, Columbus International Film and Video Festival 1996; International Health & Medical Film Festival finalist.

In this video entomologist and Harvard Professor E.O. Wilson discuss the vital role insects play in ecology and in all life on earth. If insects disappeared, the natural world as known now would collapse in a matter of months. Insects are an integral part of life. They pollinate most of the world's flowering plants, break down organic wastes to produce soil, and they are a source of food for many animals and plants.
