They ve been with us so long, we take them for granted, but plastic shopping bags were introduced as recently as 1977. It has been estimated that the world s annual consumption of plastic bags has reached almost a trillion, and 53 percent of those come from grocery stores. To combat the profusion of plastic, paper bags were re-introduced as an environmentally friendlier alternative. But are they?Though plastic bags are convenient and cheap, they do not biodegrade; they only photodegrade. That process, in which sunlight breaks down plastic into smaller and smaller pieces, can take up to a thousand years.Plastic bags use up natural resources, consume petroleum in order to be manufactured, create litter, choke marine life and add to landfill waste.Paper bags, though biodegradable, take more than four times as much energy to manufacture (which in turn produces greenhouse gases) than plastic bags.
