I had the honour of participating in a healing walk through the Alberta tar sands on Sunday, Aug. 14. Organized and led by Indigenous people and welcome to everyone, roughly a 100 walkers trekked through a 13-kilometre loop that could be called the Ground Zero of Alberta's dirty oil industry. We witnessed the images you are probably familiar with by now: the industrial plants spewing smoke into the air, the enormous tailings ponds that are deadly to all life, the moonscape denuded of trees or anything green.
