The difference between Atlantic Salmon and Pollack (in German: Lachs and Seelachs) was explained in the aquarium of Multimar when 21 young people from 15 European countries participated in a Wadden Sea Climate Training, and got the opportunity to experience first-hand the world’s most important inter-tidal zone on the frontline of climate change. The training, organised by the British Council in collaboration with experts from UNEP/GRID-Arendal and with the support of Youth in Action, took place on Hallig Langeness, a low-lying island in the Schleswig-Holsteinisches Wattenmeer National Park (Germany). The region is an important testing ground for policies and measures to adapt to climate change, the effects of which are already being felt in the ecosystem.
