The other day, in the midst of a heat wave that suffocated central Canada, this newspaper brought us the story of a five-year-old at a public school in Ottawa, sent to hospital for heat exhaustion. The accompanying photo shows the child and his mother seated on a picnic table in the schoolyard, surrounded by grass and pavement – and one tree. As a forester, I volunteer with a program of Forests Canada called Forestry in the Classroom, whose goal is to connect ”the next generation of forest stewards with forestry and environmental professionals.” This spring I visited a school in north Toronto to take a class of Grade 5 students to a nearby forested ravine, to help them identify trees and to evaluate tree health. On my arrival at the school, I was shocked to find the playground a barren wasteland.
