Invite family friends to join you on a picnic (following appropriate social distancing guidelines), and tell everybody it will be a "plastic free" event. No plastic wrap or plastic bags or single-use tableware allowed!
Instead, encourage guests to pack more sustainably with beeswax wraps, reusable bottles, reusable containers and more. To save on shop-bought snacks, you could make your owncrunchy wholewheat crackers or corncob popcorn (so fun!)!
