The Nature of Things is a Canadian television series of documentary programs. It debuted on CBC Television on November 6, 1960. Many of the programs document nature and the effect that humans have on it. The program was one of the first to explore environmental issues, such as clear-cut logging. The series is named after an epic poem by Roman philosopher Lucretius: "Dē Rērum Nātūrā" — On the Nature of Things.

While the earliest works of art of mankind depicted horses, the early history of the two species remains largely unknown. From the last nomadic peoples of the Altai Mountains to the Bedouins of the Arabian Peninsula and the Blackfoot Indians, Canadian anthropologist and filmmaker Niobe Thompson traveled the world for two years. He went to meet these communities who live in osmosis with their horses, and tried to understand the history and the nature of the very special bond between man and animal. At the same time, the work of German evolutionary biologist Martin Fischer allows, thanks to a 3D animation, to bring back to life the ancestor of the horse, whose appearance is surprisingly reminiscent of a small fox.

In 2005, a small group of scientists and filmmakers agreed to leave everything behind for more than a year to sail to the Antarctic and live in isolation. Following in the path of the greatest explorers, expedition leader Jean Lemire and the crew of the Sedna IV dedicated themselves completely to measuring the threat posed by global warming in a place where Earth is particularly vulnerable. The resulting film, is a record of their incredible 430-day journey that inspires equal measures of fear and admiration. Alternating between captivating images of beauty and serenity, and spine-tingling sequences where the ship's crew finds itself on the edge of catastrophe, this is an expedition where danger and wonder are inextricably linked.

Locals call it the "arribada", Spanish for "arrival": the magical days and nights when tens of thousands of sea turtles come ashore on Costa Rica's Pacific coast to lay millions of eggs. In 'Turtle Beach' Canadian naturalist and cinematographer Hugo Kitching follows a team of international scientists on a groundbreaking expedition to uncover the mysteries of this rare phenomenon.
