This Canadian singer-songwriter co-founded the environmental group PERL (Protecting Escarpment Rural Land), which is campaigning to prevent a proposed gravel development from harming the Niagara Escarpment, a wild area along the U.S.-Canadian border that includes Niagara Falls. Harmer walks the talk with her commitment to the cause — she hiked along the Escarpment with her acoustic band to play shows and raise awareness throughout the area, a tour documented in the film Escarpment Blues.
