Climate change is not a choice. It is a planetary problem that humanity has to face in order to find solutions by trying to slow it down, adapt to it and live with it. Global warming and the preservation of biodiversity have a global impact but the sustainable solutions will be local. By learning about global, national and regional strategies and agendas for sustainable development, our project will encourage our students to become factors of change and develop strategies and practical solutions to deal with environmental problems and climate change in our schools and regions as parts of Europe by creating sustainable green spaces adapting to the challenges of climate change. The interdisciplinary project will link two geographically distant regions of Europe together through creative cooperation and offer an inspiring learning experience that opens up different future prospects allowing students to develop and practice many of the 21st century skills required by Europe’s future citizens. Using English as the work language and implementing eTwinning activities throughout the whole project, all involved students will work in international groups to exchange their research on the challenges of climate change in Northern and Southern Europe and present it to their partners. They will create a log book in form of a webzine, a digital herbarium, a video documentary and green spaces in their high schools.
