School cafeterias offer students daily lunch choices, but school-provided meals can generate serious waste. Students in rural northeast Michigan took a closer look at their lunchroom waste as part of a “Food for Thought” project led by the Northeast Michigan Great Lakes Stewardship Initiative, the Community Foundation for Northeast Michigan, and Michigan State University Extension. They performed a lunch waste audit to investigate their lunchroom trash and to brainstorm solutions that prevent plastics from becoming marine debris in the Great Lakes ecosystem.
