Ever see stray cans and bottles and other trash carelessly strewn on the street? The reality is it probably wasn't from a litterbug, but from improperly filled trashcans. When you throw trash into the can without using trash bags, you risk items being accidentally knocked out or falling out on collection day. These small items -- which are often lightweight -- can end up on the street, clogging storm drains or eventually littering wooded areas. Do the right thing and make sure all refuse is properly bagged before tossing it out.
