Little pieces may get lost. Look for a guarantee. Many companies who claim to have well-made products will promise to fix their product if it breaks. Only about 700 paper bags can be made from one 15 year-old tree. A large grocery store can use that many bags before lunch.
Plastic bags start out as either oil or natural gas.
Oil and natural gas are non-renewable resources. This means they can't be reused, and when they are all gone, they are gone forever Also manufacturing these bags adds a lot of pollution to the environment. Once plastic and paper bags are used and go to the landfills, they stay there for hundreds of years. When you go shopping with a parent, take some paper bags with you. At the check-out counter, ask the clerk to put your groceries in reused bags.
