Washington stops use of Styrofoam containers

From June 1st, foam or Styrofoam containers like cups, plates, and trays will not be used in Washington, USA. Usually, such foam containers are used once and thrown away. The containers break into tiny bits and are blown away by the wind. They end up in the rivers and pollute the waters for the fish living there. Hereafter, Styrofoam will be used only to pack medicines, meat, eggs, etc.
