S38 E6 • Race for the Future

When David Suzuki was born 1936, there were two billion human beings. In his lifetime, our population has tripled. And in that time, virtually all of the modern things that we take for granted, the birth control pill, computers, jet planes, satellites -- you name it, have become a part of our daily lives. When you add all of that together, our numbers, our consumption, our technology, our economy -- we have become something never seen before on this Earth. A species so powerful we are changing the biological and physical features of the planet.

S38 E7 • Race for the Future, Part 2

In our previous program, we saw how science and technology have presented us with a paradox -- a world in which we are increasingly powerful yet increasingly vulnerable at the same time. We looked at the consequences of our ever- increasing consumption of the earth's resources, at the growth of environmental consciousness. A world where it sometimes seemed that we had little sense of our real goals. Tonight, the stakes get higher as we travel into the future.

S38 E8 • The Sleep Famine

A nuclear power plant whether Chernobyl or this one near Toronto, is not a place you want run by people who are half asleep. But from all over, from surgeons, police, parents, you hear the same complaint -- they're tired. They can't get enough sleep. It's been called a sleep famine. Part of the price we pay for a non-stop 24 hour a day lifestyle. Life goes on around the clock. And in our 24 hour a day, seven day a week society, one of the major victims has been sleep.

S38 E9 • Do Parents Matter?

These are 12-year-old Americans. Like all children their age, their personalities are already well defined. We assume their personalities come from their parents but a controversial new theory says we've got it all wrong. When someone proposes an idea that runs counter to what most people think, a controversy results. The influential role of parents has rarely been questioned until now.

S38 E10 • Weather: Dragons of Chaos

Violent thunderstorms develop in the heat of spring and summer. The heat quickly draws large amounts of water vapour into the air. As the cloud grows, it rises high into the atmosphere. Eventually it hits a layer of cold air -- the boundary between the troposphere and the stratosphere. Blocked from rising, the cloud spreads into an anvil shape. Within the cloud, the droplets combine and grow until gravity draws them back to Earth. It takes a million droplets to make a single rain drop.
