This year's Clean Up takes us to Gersau on Lake Lucerne. Lakes and bodies of water are sensitive habitats. Unfortunately, more and more waste is accumulating here too - often invisibly beneath the surface of the water. Plastic, metal and other garbage endanger animals, plants and ultimately the water quality on which we all depend. With our Clean Up, we are making a concrete contribution to the protection of Lake Lucerne. Every item collected counts, and divers are just as welcome as helpers above water. Anyone who wants to can also support us with a stand-up paddle and collect the garbage that the divers bring to the surface. Together we show that responsibility for our natural environment is not just a word - it's an action.
