I cloth diapered and we use reusable cloth for clean up. We have a backyard garden where we grow veggies and we support our local agriculture by buying what we don't grow at the farmers' market. When the need for the grocery store arises we use reusable canvas bags to tote our food. We make our own Earth-friendly cleaning products and buy 100% organic. Our just-turned-4 year old knows more about the evils of GMOs than most adults and he understands that conventional farming isn't sustainable. Additionally, I use my sewing machine to re-purpose old clothing. We also reuse containers and have minimal waste on trash day, since we recycle and compost.
