Global change in climate and biodiversity – which effects does it have and how can it be countered? As this change affects different regions in different ways , this project involved schools located in climatically and geographically diverse regions: Estonia, Hungary, Germany, Tenerife (belongs to Africa) and Martinique (belongs to South America). Through varoius activities participants have realized how climate change affects different parts of the world and how each individual can act responsibly and sustainably. We have also developed a transnational interdisciplinary spiral curriculum with comparative elements, involving modern media and bilingual teaching.
