Canadians use between nine and 15 billion plastic bags a year, enough to circle the Earth more than 55 times, according to Greener Footprints. (U.S. citizens use about 100 billion a year!) Few plastic bags are recycled. Plastic bags are bad and for the most part unnecessary. Many of us older folks remember a time, only a few decades ago, when we didn't have them. Sure, they're convenient, but is that an excuse to damage the environment and the life it supports?
