The Secret of Life on Earth begins where life apparently began three-and-a-half billion years ago. The film shows some of the key developments in plants that made possible the web of life. Micro, macro, and time-lapse photography delivers close-ups of special relationships between plants and animals: barnacles feeding, microscopic plankton, tiny grasses flowering, and pollinators at work. The interdependence between plants and animals is portrayed as an unwritten “green” contract.”
