The Working Group Science and Arts for Sustainability of the Helmholtz-Gymnasium Hilden (HGH) has been setting the tone for collaboration with Mundus marisin Germany. This collaboration started in earnest with their successful participation in the Amsterdam exhibition 'Sustainable Seas Through the Eyes of Art' and continued with exhibitions in Brussels and at home.
Since 2009, Ansgar Beer, the couch of the working group and founding member of Mundus maris, has been elected Responsible Teacher for Sustainability at the school... with interesting results as can be seen from the graphical encouragement for healthy food and much more. Read on in the section about the HGH.
Other schools are, obviously welcome to join as well.
