Getting outdoors is one of the great pleasures in life. But our expeditions into natural environments can also cause real horror stories to unfold. Discarded rubbish causes the waterways to become clogged, a campfire can leave a nasty visual scar that can last for years. How can we avoid causing these problems? This program examines ways to minimise our impact when enjoying the outdoors.

Any ecosystem needs energy to sustain it, and the organisms within it. This energy comes in massive quantities from the Sun, although only a tiny fraction of the solar energy hitting the Earth goes towards sustaining life. The flow of energy through an ecosystem is complex, and vital to sustaining all life within it.

What exactly are greenhouse gases? Are they really causing climate change? Global warming has suddenly become the hottest environmental issue, and this program clearly explains the science of the greenhouse effect and the evidence that we are causing climate change.

This program begins with an explanation of nanotechnology, and then demonstrates micrometers and nanometers. Viewers will also examine the special properties of nanoparticles, the gecko effect, carbon nanotubes, surface energy; hydrophilic and hydrophobic surfaces as well as the lotus effect.

This awe-inspiring video shows of the process of human reproduction from conception to birth. It explains how mitosis and meiosis create genetic variation, how the ovum travels from the ovary to the uterus, how sperm pass the cervix, how one sperm achieves fertilization with the ovum, how the zygote begins cell differentiation, and how the embryo grows into a fetus ready for birth.

What can we learn from other cultures about food and nutrition? Some countries share our love for food yet manage to avoid our epidemic of obesity. How do they do it? By studying how other cultures eat, we can gain some useful (and tasty) ideas to adapt to our own needs.

This program challenges all eaters to make decisions about food. Should people eat lots of meat? Just a little? None at all? Are vegetarians on to something or just a fringe group afraid to eat a creature that looks cute? Is meat a key part of a healthy diet or does it contribute to cancer and heart disease? It’s easy to find extreme views on this subject, but what are the real issues?

One result of increased global trade and travel is that we all have multi-cultural stomachs. This video examines the multi-cultural origins of many foods and unearths a few surprises. Viewers learn chili isn't Mexican, spaghetti and meatballs is uniquely American, chop suey doesn't exist in China, and sauerkraut was a Chinese invention.

From Albany to Buffalo, and from 1825 into the 21st Century, the Erie Canal has made American history. Tom Grasso, President of the NY State Canal Society, takes us on a tour of the Canal, past and present, in this videotape.Carrousel Menagerie explores the superb carousels of yesteryear and the people who preserve their heritage today.

Dave Thomas: Made to Order. Story of the lovable guy behind the Wendy's fast-food empire. He began with Kentucky Fried Chicken and invented the famous bucket of chicken with Colonel Sander's face on it. After leaving KFC, he started in Wendy's commercials in 1989--the first of 500 thus far.
