Homework forces families into hours of unnecessary screen time that drives up home energy use. We know from PISA data that once you get past about an hour a night, extra homework produces essentially zero academic gains, yet it keeps routers, laptops, and lights burning in millions of households every single evening. For a planet in a climate crisis, that's waste we can't afford. Time spent on worksheets is time kids aren't outdoors, moving, sleeping, or just being kids. We can cut homework entirely and lose nothing educationally while meaningfully reducing energy demand. If the learning isn't there and the planet can't afford it, then it shouldn't exist.
