The Great Butterfly Hunt tells the story of incredible journeys. The first is that of the remarkable Monarch migration, which is the longest insect migration on Earth, is. The second story is that of Fred Urquhart, the determined Canadian scientist who spent 40 years trying to discover exactly where the butterflies mysteriously disappeared when they flew south for the winter. The Great Butterfly Hunt is a beautiful and colourful one-hour program that combines the spectacular visuals from Flight of the Butterflies with the production’s behind-the-scenes look at how such films get made. On Thursday, January 2, when many Canadians will be groaning about the long grey winter ahead, The Great Butterfly Hunt will remind audiences of the promise of spring. And, at a time when the monarch population is in rapid decline, viewers will have an opportunity to watch one of Nature’s most dramatic feats unfold.

The air we breathe, and all the food we eat, is created from water, sunlight, carbon dioxide and a few minerals. It sounds simple, but this process is one of the most fascinating and complicated in all of science, and without it there could be no life on earth. For centuries people believed that plants grew by eating soil. In the 17th century, pioneer botanists began to make the connection between the growth of a plant and the energy from the sun. They discovered how plants use water, sunlight and carbon dioxide to produce sugars - how, in fact, a plant grows. The process of photosynthesis is still at the heart of scientific research today, with universities across the world working hard to replicate in the lab what plants do with ruthless efficiency. Their goal is to produce a clean, limitless fuel and if they get it right it will change all our lives.
