Several celebrities are joining an effort to get you to kick the habit of using plastic straws.

According to the National Park Service, 500 million plastic straws are used in the United States every day. Environmentalists say that straws often end up in landfills or the ocean after being used once.

Celebrities have joined a campaign called Strawless Ocean to push consumers to stop using them.Not only are some businesses getting rid of them, so are several cities.

In Seattle, a ban of plastic straws and utensils goes into effect in July. Malibu is making a similar move in June.
