At ground level, shallow seas, broad beaches, dunes, and waterlogged hollows seem to comprise a chaotic environment. In fact, there is order and form, produced by the interaction of wind, vegetation, and moving sand. Because sand dunes develop rapidly, the development of a landform can be observed. Measuring wind velocity demonstrates how saltation, sand movement, and erosion happen. The program demonstrates the morphology of dune development and...

Young minds are introduced to nature and all its beauty, and a foundation is laid for a lifelong love of wild life, and places in the following three episodes: Bath Time (When Sammy hides because he doesn't want to take his bath, the Explorers set out on an adventure to see how other wild animals clean themselves); Mighty Oak (An acorn hits Izzy on the head and the Explorers think the sky is falling); and Fly Away Home (the Explorers follow some birds...

Nature or Nurture?" is a long-running debate in the social sciences, one heavily-influenced in the popular imagination by the idea "DNA is destiny" - the belief human behavior is broadly determined by a "good" or a "bad" roll of the genetic dice. While human genetics is an important part of our story, recent developments in the field of epigenetics suggest that the way our genes actually work can be critically shaped by the environment in which we...

This program shows the process of sedimentation, which has preserved those life forms extant at the time the rock was formed and-most strikingly where the Colorado River has cut through the Grand Canyon-exposes a veritable history of life on earth; presents the stratified evidence that simple organisms populated the earth first, followed by increasingly complex forms; demonstrates modern techniques for dating rock samples; and explains why fossils...

Shows how human desires are an essential, intricate part of natural history. The program will explore the natural history of four plants -the apple, the tulip, marijuana, and the potato - and the corresponding human desires - sweetness, beauty, intoxication and control. This two-hour documentary begins in Michael Pollan's garden, and roams the world, from the fields of Iowa to the apple forests of Kazakhstan, from a medical marijuana hot house to...

This film examines escalating threats to shark population including habitat destruction of reef ecosystems and over fishing that are causing Pacific reef shark populations to plummet. It examines the most brutal assault threatening shark abundance: that of finning sharks for shark fin soup. Compelling interviews with leading marine biologists and conservationists reveal these driving forces behind the drastic reduction of many shark populations.
