Paper or plastic? Regarding straws, the Milwaukee Brewers have chosen paper. In recognition of Earth Day, the team announced Monday afternoon that plastic straws would no longer be used at Miller Park.

Instead, fans will receive paper straws, and only if they request a straw at all. "Plastic straws are one of many items that contribute to the 8 million metric tons of plastic waste impacting our oceans each year," the Brewers stated via Twitter, as reported by WTMJ in Milwaukee.

It's a movement that's been about a year in the making, and picking up momentum.

Guaranteed Rate Field, home of the Chicago White Sox, made the transition to biodegradable straws last season, according to foodrepublic.com, and other MLB parks will transition out of necessity. AT&T Park in San Francisco will bend to the will of its culinary service provider Bon Appetit Management Company, which announced it will go biodegradable by September of this year, and Yankee Stadium, Citi Field and all food-serving venues in New York's five boroughs faced local government intervention beginning last year. Last August, what is now called Dignity Health Sports Park on the campus of California State University Dominguez Hills got the jump on California governor Jerry Brown when it announced it will only offer paper straws to customers — and only upon request — at its concession stands.
