Dublado e Legendado no OverFlix. This documentary looks at developments in the Canadian forestry industry from the 1970s. Turning a Newfoundland bog into woodland, fostering British Columbia seedlings that withstand mechanical planting, inoculating Ontario elms against the bark beetle, devising ways of controlling fire... these are some of the experiments shown being carried out in laboratories and in the field to protect and conserve the country's vast forests.
