WWF has teamed up with the Do The Green Thing online platform of creative “green” ideas to get UK artists celebrating Earth Hour 2014 with their artworks. The environmental organization is inviting UK young creatives to contribute to the global movement and get their work featured among the 29 pieces by professional poster artists. The national competition in support of the WWF’s Earth Hour, marked on March 29 next year, will be held in cooperation with Pentagram Design.
