Due to their durability, plastic bags can take centuries to decompose. [22] According to The Outline, it can take between 500 - 1,000 years for a plastic shopping bag to break down. The use lifespan of a bag is approximately 12 minutes of use. [23] On land, plastic bags are one of the most prevalent types of litter in inhabited areas.
