What was the most important thing Farley Mowat did for Canada?

Farley Mowat was a famous Canadian writer.  He wrote about many topics, including Native people and environmental issues.  In 1963, he wrote a book called Never Cry Wolf.  This book told about his time spent in Northern Manitoba where he studied Arctic wolves.  A small airplane dropped Mowat off on a frozen lake, and he found a den of wolves nearby.  He studied them for a time.  His book caused controversy in Canada because many people believed that there were too many Arctic wolves and that they "should be exterminated."  He brought a new level of awareness for the wolves.  Mowat also visited the Canadian Arctic, where he met and observed groups of Inuit people.  He found their living conditions to be poor.  He found people to be starving and he blamed the Canadian government.  He wrote the books People of the Deer and The Desperate People about the Inuits he had met.  Mowat brought awareness to the plight of the Inuits.  He was a man who brought awareness to overlooked groups with his writings, and that was the most important thing he did for Canada.
