An average trekker leaves behind approximately 100,000 kgs of water bottles per year. During average trekking of a week , trekker drinks up to 50 litres of water. Each trekker leaves behind 50 PET bottles along the track. PET bottles can take 1,000 years to biodegrade. Nine out of 10 water bottles end up as garbage or litter, and that means millions per day. PET bottles require massive amounts of fossil fuels to manufacture and transport, leaving behind carbon foot prints. Billions of bottles show up at landfills every year. The entire energy costs of the lifecycle of a bottle of water are equivalent, on average, to filling up 250 ml of each bottle with oil. "Making bottles to meet Americans' demand for bottled water requires more than 1.5 million barrels of oil annually, enough to fuel some 100,000 US cars for a year," according to the study.
