In 1973, at the age of 26, Weyler received his first journalism position at the North Shore News in Vancouver, B.C. Canada. Later that year, he began covering the original Greenpeace whale campaign story, and later, from 1975 to 1980, served as editor and publisher for the "Greenpeace Chronicles" newspaper.  This paper was one of the first international environmental publications, with stories by writers Lawrence Ferlinghetti, Robert Hunter, Paul Watson, John C. Lilly, Kitty Tucker, Ben Metcalfe, and David Garrick, and art and cartoons by cartoonists Ralph Steadman and Ron Cobb.
