NOVA: Insect Alternative
Overview
In a world that each year loses up to 40 percent of its crops to insects, some form of pest control is desperately needed. But chemical pesticides have backfired. Pesticide-resistant insects frequently develop, and previously harmless insects have become devastating infestations. Farmers have found themselves trapped on a "pesticide treadmill"—the more they spray, the more they have to spray. NOVA examines several alternatives for pest control.

Episode 15: Laser : Light of the 21st Century
When first invented 18 years ago, lasers were called "a solution looking for a problem;" nobody could think what to do with them. But in fact research scientists immediately began to exploit their pure colors and near-perfect focusing ability. Today lasers have grown into a billion-dollar business. They are used in construction, manufacturing, clothing, dentistry and medicine. And the future uses of lasers are likely to be of major significance as the means of achieving nuclear fusion and as a very high efficiency communications medium.
Episode 17: The Desert's Edge
For thousands of years people have managed to live in deserts all over the world. But in recent years, a growing population and the demands of the international market have put more stress on these poor and easily exhausted lands. NOVA examines the consequences and possible solutions to desertification.

Episode 14: The Road to Happiness. : The Life and Times of Henry Ford
Henry Ford, a great friend of Edison, was a film enthusiast who amassed some one and a half million feet of film during his lifetime. Deposited in the National Archives and known as the Ford Film Collection, it covers not only the Ford family and Ford Motor Company but also contains newsreels, and general films produced under Ford. Using the Collection, NOVA profiles Ford's life and times.
Episode 18: The Tsetse Trap
NOVA explores Bovine sleeping sickness. Spread by a fly, it is a deadly disease that poses a threat to Africa's cattle.
Episode 13: Battle for the Acropolis
The fortified plateau above Athens known as the Acropolis is the site of some of the most remarkable architecture in the world: its marble structures built in the fifth century BC, including the renowned Parthenon, represent the artistic peak of classical Greek architecture. NOVA examines how the heavily polluted air of Athens produces acid rain which is dissolving the marble sculptures and columns; and how iron tiles used extensively in repair 40 years ago are now rusting, expanding and shattering the stone structures.
Episode 19: Memories From Eden
Traditionally zoos were designed neither for people nor animals; barred cages taught people more about their separation from nature than about an animal and its habitat. But just as man has realized that he has all but destroyed much of the world's wilderness and its wildlife, he is realizing that the zoo may be the last refuge for wildlife. NOVA visits several United States zoos to examine a variety of activities of concern today: breeding, public education, creative new animal habitats, and the reintroduction of animals to their natural environment.
Episode 12: Still Waters
NOVA shows a year in the life of a beaver pond and includes almost every life form that exists in, on, under, around and above the water, from the microscopic plant life of summer to the eagles feeding on carcasses of deer that collapsed on the winter ice.
Episode 20: A Whisper from Space
In 1965, Arno Penzias and Robert Wilson, two radio astronomers at Bell Telephone Laboratories, discovered faint, but ever-present, microwave signals from space—the most ancient and most distant signals detected by man: the oldest "fossils" in the universe. NOVA explores the current surge of cosmological discovery that continues to aid scientists in the "cosmic archaeology" of digging into the history of the universe.
Episode 11: Icarus' Children
In the summer of 1977 Paul MacCready, a California scientist and businessman, won the coveted Kremer Prize. His achievement was to design and build an airplane which completed, unaided, a one-mile figure-eight course entirely under the power provided by the pilot himself. This is the story of those many failures and MacCready's success.
Episode 21: Alaska: The Closing Frontier
Congress is currently considering a proposal that would double the size of America's national park system by designating a sizeable chunk of Alaska as off-limits to developers. NOVA explores the public debates on Alaska, such as the construction of the oil pipeline—a proposal that has sparked a bitter controversy between conservationists and developers.
Episode 10: The Mind Machines
Today's scientists may be creating their own successors. Work being done in Artificial Intelligence (AI), a branch of computer science, only suggest that in the not too distant future, machines will outpace their creators. NOVA examines the possibility.
Episode 9: The Case of the Ancient Astronauts
NOVA investigates the theories of von Daniken and others that the Earth has been visited by intelligent beings from outer space. Among claims examined are: that the building techniques used in the Great Pyramid of Cheops are so advanced that only an extraterrestrial intelligence could have built it; and that the engraved stones of Palenque in Mexico depict an ancient astronaut at the controls of a space rocket.
