Through revealing interviews with experts and victims' families, this gripping documentary examines the problem of deadly foodborne illness in the US.

PRIMAVERA is a three dimensional film featuring puppets that work in the so called telescope system which tries with the help of stylised images to visually depict the great variety existing in nature, the food chain and variations in the reproduction of different living organisms. The entire film is seen through the eyes of a butterfly larva.

Uses animation and live action photography to describe good food chains, almost all depending ultimately on green plants, and relates these food chains to the larger concepts of the oxygen-carbon dioxide and the nitrogen cycles, and to the unending pattern of life, growth, and decay which is known as the food cycle.

This is a documentary about the fragile and complex marine ecosystem in the Bay of Fundy. The film traces relationships within the food chain - from tiny plankton to birds and seals and finally to whales and humans. The film is a plea for careful management of our ocean resource and was first telecast as part of CBC's Nature of Things series.

'The Lost Salmon' chronicles the plight and potential recovery of the iconic Spring-run Chinook Salmon of the Pacific Northwest. Faced with extinction in many river systems of the West, a new genetic discovery could aid in their recovery. Once teeming in the millions and a sacrament for the oldest civilizations in the Americas, time is running out for this genetically distinct wild salmon.

Three invertebrates - a water flea, a green hydra, and a planarian flatworm - engage in a food-chain fight after the hydra tries to eat the flea.
