Hard and soft plastics are the most common types of waste encountered at altitude by mountaineers, the first survey of its kind has found — with two thirds of mountaineers spotting litter most or every time they set foot on a mountain.While much attention in recent years has gone to the impact of waste – including plastic waste - in the world´s oceans, pollution in mountain regions has rarely made the headlines.A new global survey, led by Björn Alfthan and Laurent Fouinat from GRID-Arendal, sought the voices of mountain guides, mountaineers and other mountain enthusiasts to shed light on the extent and nature of waste pollution in the mountains.
