Winner of many international awards, this classic natural history film examines the ecology of a marsh and represented a major development in the genre. It avoids the cute, anthropomorphic approach then common in natural history films in favour of respecting its subject and its audience. World in a Marsh was also released theatrically in the Canada Carries On series in a shortened version titled The Lively Pond.
