Singer Sheryl Crow and Whole Foods Market have teamed up to create a limited-edition reusable shopping bag, called "A Better Bag".

"I am a big believer in doing what you can, even if it's something as small as reducing the amount of plastic we each use daily that ends up in landfills, whether it is plastic bags, water bottles or product packaging," Crow said.

The bag design features a charcoal sketch of a tree with words written by Crow for the project.

The bag is made from 80% post-consumer recycled plastic bottles.
Whole Foods said it hopes the bag launch will also raise awareness of the Natural Resources Defence Council's Simple Steps programme, which calls on people to make small changes to help the environment.
