One of the greenest things you can do when taking care of your yard is to leave the glass clippings on your lawn and not dispose of them in trash bags. But it's also important to make sure those clippings (and leaves and other organic yard debris) stay in your yard and not on hard surfaces like your driveway and sidewalks. The reason? When it rains, these items can end up in storm drains and waterways. It's better for them to decompose naturally in your yard instead.
