13．Plastic bags are not costly to produce．They are also strong and easy to carry．This is why they are a popular container in much of the world．But they are also a major source of pollution．It can take hundreds of years for plastic bags to break down．As they do，tiny pieces can poison soil，lakes，rivers and oceans．Therefore，environmental experts urge people to reuse and recycle plastic bags．
Maryland artist Allita Irby does just that．It starts with the morning newspaper．What is more important is getting that plastic bag the paper comes in．The mixed media artist recognized its rich possibilities about three years ago．"As I was taking the newspaper out，I felt the texture of these bags，and they were soft．I just looked down and realized it would take three to make a braid．"Since th en，Irby has been using plastic bags to create abstract lines in her artworks．
Before incorporating（吸納）plastic bags in her pieces，Irby used natural materials like feathers，leather and dried plants．All those elements represent her Native American ancestry and identity，like one of her works called"Navaho Bundles"．
Ms．Irby's neighbors praised her ability to turn waste into treasure．Some，like Charlotte Hogan，asked the artist to teach them how to create art using plastic bags．"I think it's fascinating．I do plan to share it with my seniors at my church．"One of Irby's neighbors Aleta Meyer expressed her surprise，"I have never given any more thought to what to do with a plastic bag．This is definitely different．"
Shirley Watts also lives in the neighborhood．She plans to show others her art．"I want to make a masterpiece that I can put in a frame and put it up on my wall and then I know that I did it．"
"Making art with found materials is not a new idea．Anyone can do it．Recycled paper，cloth and metal goods can become beautiful pictures and sculptures，"Allita Irby said"I think we're all artists really，and there is beauty all around us．"The artist also said all that you have to do was open your eyes and bring the outside in．
