Scaling mountain peaks to collect trash is a crusade against global warming for a Swiss couple with three kids. Having scaled several peaks and done the cleaning act in over 45 countries, Dario Schowoerer’s NGO TopToTop which is supported by the UN, has collected 20,000kg of dump from beaches and mountains all over the world. After having collected trash of over 300kg of oxygen bottles, aluminium foil and plastic containers at Aconcagua in South America, Dario and his team on their way to Mt Everest know exactly what kind of garbage awaits them.
