Plastic bags are everywhere. Look around and you will notice that plastic bags are the most common litter. Tangled in trees and fences along roads, floating in water, lying on the ground in parks and forests, surrounding garbage bins, washed off on beaches. Because they are so lightweight, plastic bags get easily picked up by wind and travel long distances by wind and water to pollute the nature.
Plastic bag litter has even caused great problems in some areas. For example, millions of discarded plastic bags clog water drainage channels and sewers in urban areas of Bangladesh. When the monsoon rains start, streets get waterlogged just after the first few minutes because the water cannot pass through clogged sewerage pipes.
