Although this Cubbies fan isn't fond of the New York Yankees, I spent an enjoyable May afternoon at a ball game in the new Bronx stadium. I was pleased to see that the stadium management team is making an earnest effort to be environmentally progressive. The stadium's food containers are bio-degradable, and separate waste bins for trash, plastic and compost are stationed throughout the ballpark. These bins are labelled clearly and usually positioned next to one another.
Unfortunately, your average baseball fan doesn't know what "compost" is. I snapped the below picture of a Yankees fan throwing balled-up napkins into a "compost" receptacle, and witnessed similar mistakes all afternoon. Depressingly, the "plastic" bins fared little better.
Perhaps Yankee Stadium management needs to station waste educators near the bins? The ticket prices are surely high enough to cover the cost!
