Say "no thanks" when a store clerk asks if you want a bag for your purchase. In 2012, 2.86-billion plastic bags were used annually in Canada – 200 for every one of us. It takes about 1,628,000 litres of oil to produce 100 million plastic bags. A reusable cotton bag is a great alternative to a plastic bag and comes in many designs and patterns. A great way to make a fashion statement while saving the planet!
