It’s a single piece of news, but a revolution in its own right: starting Friday, the Oakland A’s will serve drinks in compostable cornstarch cups, and provide compostable cutlery too. McAfee Coliseum staffers will dig the items out of the trash at the end of each game — pausing only briefly to wonder if they should have taken that internship with Dad’s friend’s company instead — and ship the whole beery, mustardy mess to a composting facility.

It’s all part of stadium manager George Valerga’s plan to reach a 75-100 percent recycling rate. And the San Francisco Giants are considering composting too. OK, OK, California did pass a law requiring special-events venues to increase their recycling. But hey, whatever it takes to make America’s ballfields greener. Let’s go A’s!
