Greenpeace activists and volunteers from the local group created a dolphin replica, with the help of artist George Mpardakas, at the beach of Thessaloniki, using already used plastic bags. The art installation aims to underscore the major threat that our seas and marine life are facing, due to plastic pollution.

The dolphin sends a clear message: our dependence on single-use plastic is choking our cities, which are full of garbage, and our seas too, threatening marine life. The single use, throwaway culture is arguably one of the biggest follies of humanity.
