101. Protection, Please
How can we protect our environment? Why is environmental protection so important? This program addresses both questions through relevant examples.
102. Migration Mystery
Why do animals migrate? How do animals manage to navigate such incredible distances? This program explores these questions; answering the "why," in the case of the monarch butterfly and the gray whale, but still only guessing at the "how."
103. Prairies Past
The North American prairies of the past were vast, but today only islands of prairie remain. Why should we care? This program introduces the student to the prairie through a look at climatic conditions, vegetation and the animals it supports-from prairie dogs to
bison.
104. Here Today, Gone Tomorrow
The broadleaf trees of the deciduous forest are full and green in the summer, colorful in the fall and bare in the winter. Have you ever wondered why? This program answers that question and takes a closer look at one type of forest biome.
105. The Environment
Discussion centers on the components of the biosphere and explores the interdependent relationship of the parts of an ecosystem. This program includes video from a southeast pine forest, different life forms from the Smoky Mountains and an overview of different types of ecosystems.
106. Symbiotic Relationships
Introduces the three types of symbiotic relationships that exist between two different species that live together: commensal, mutual and parasitic. This episode takes a look at how ants and plants get along, the blueberry bee in action and a humorous look at parasites.
107. Endangered Species
This program examines the factors that influence whether a species will survive, and uses current examples that distinguish between endangered, threatened and extinct species.
108. Succession
This program follows the stages and processes of succession from a pioneer to a mature community. U.S. pine forests, the Amazon rain forest and even a clay deposit that was once the sea floor are examined.
109. The Big Picture
The problems posed by overpopulation-- limited resources and pollution--are explored. The effects of disease, war and starvation on population growth are also investigated.
110. Air Today, Smog Tomorrow
Sources of air pollution--volcanoes, pollen-producing plants, cars, industries, cigarettes, oil-based paints, dry-cleaned clothes--are examined.
111. Water Everywhere
Three basic water resource problems--too little water, too much water and dirty water--are explored.
112. Dust to Dust
The importance of topsoil and the harmful effects of erosion are the topics of this program. Ways to decrease erosion are investigated.
