The CBC plans to celebrate the 50th year of The Nature of Things along with host David Suzuki’s 75th birthday. On March 13, the CBC will air Force of Nature: The David Suzuki Movie, in which the Canadian scientist, educator, broadcaster and activist will give what he’s dubbed “a last lecture — a distillation of my life and thoughts, my legacy, what I want to say before I die.” On March 24, CBC will air a Nature of Things retrospective.
