Newfoundland and Labrador has announced it will become the second province to ban plastic bags. The provincial government introduced legislation allowing it to ban their use at stores and other retail outlets It says the ban won't take effect for between six and 12 months, to give consumers time to get in the habit of bringing reusable bags. Prince Edward Island passed a similar ban last June, to take effect this coming July 1. Many municipalities plan similar bans, amid a national conversation about single-use plastics and their environmental impact. Newfoundland and Labrador says public consultations found 87 per cent were in favour of a ban. According to Greenpeace Canada, Canadians generate about 3.25 million tonnes of plastic garbage each year. An amount the environmental group says could fill 140,000 garbage trucks. The federal government says more than 150 million tonnes of plastic waste is clogging the oceans worldwide.
