To go zero waste, you don't necessarily need to invest in much, if any, new gear. You can grab a fork from your kitchen drawer instead of purchasing a tiny fork to tuck in your purse; you can choose to drink your coffee at the coffee shop
rather than purchase a reusable thermos; you can scrounge up a few reusable tote bags from friends who have extras rather than buying them new. All perfectly wonderful ways to go zero waste.
