No Single-use Plastics At a time when everyone is looking for alternatives to single-use plastics, Cambodia shows the way. We are starting a three-day Buddhist holy time tomorrow and it is a custom to give large rice rolls with a filling inside. No plastics, though. The wrappings are banana leaves and long grasses, the way they have wrapped these rolls for centuries. Russ Brine, Maryknoll lay missioner, is assisting with the display.
