February 1958 (age 58)

Sigurd spent time in Ottawa and Washington, D.C., working on Canadian wilderness, the U.S. wilderness bill, and national park issues. He also spoke at a Resources for the Future forum in Washington on February 27th, talking, in part, on the need to get away from a purely economic definition of resources:

We must stop talking about natural resources, recreational areas, and conservation generally in cold blooded economic terms, seeing them only as graphs and statistics, national income and expenditures, taxes, price supports and programs. We must see them from an ecological point of view involved with such inherent needs as freedom, human dignity and happiness. We must recognize the human necessity of keeping physical contact with the land, knowing now and in the generations to come the meaning of the old simplicities and satisfactions.
