Plastic bags are a popular container in much of the world，but they are also a major source of pollution which need hundreds of years to break down，and as they do，tiny pieces can poison soil，lakes，rivers and oceans．So，environment experts urge people to reuse and recycle plastic bags．

Maryland artist Allita Irby just does so．It all starts with the morning newspaper，and the plastic bag that the paper comes in．The mixed media artist recognized its rich possibilities three years ago．"As I was taking the newspaper out，I felt the texture （质地） of these bags．I just looked down and realized it takes three to make a braid （发辫）．I'll just put a few main materials in just to make it strong enough．"Since then，Irby has been using plastic bags to create abstract lines in her art works．

Before using plastic bags in her pieces，Irby used natural materials like feathers，leather and dried plants，all of which contain elements that represent her Native American ancestry and identity，like her piece called"Navaho Bundles"．"I was making a hair style，a Navaho hair style when the hair was heavy and it was looped back on itself．I took the piece and looped it back onto itself and secured it with a tie．

Ms．Irby's neighbors praise her ability to turn wastes into treasure．Some people，like Charlotte Hogan，asked the artist to teach them how to create art from used plastic bags．Aleta Meyer expressed surprise，"I've never given any more thought to what to do with a plastic bag．This is definitely different．"Shirley Watts plans to show others her art．"I want to make a masterpiece that I can put in a frame and put it on my wall and then I know that I did it，"she said．

Allita Irby says anyone can do it and all you have to do is open your eyes and bring the outside in．
