Maybe it's making for «no straw» in your drink when you go out, bringing your own
bags to the grocery store, getting coffee or a smoothie in your own cup / jar, bringing your own silverware when you're out and about, switching from paper to cloth napkins, buying
bread from a local bakery or making it yourself instead of buying in plastic, switching to a menstrual cup or washable cloth pads instead of disposable, there's so many
different ways to produce less waste.
