英文摘要	The oversupply of nutrients (phosphorous and nitrogen) in fresh and marine water bodies presents a serious ecosystem threat due to impacts on water quality through eutrophication. With agriculture characterized as a primary driver of eutrophication, the role of food consumption and trade has been the focus of recent phosphorus and nitrogen impact studies. However, the environmental impacts associated with non-food commodities are significant and yet to be characterized. Here, we link a spatially explicit treatment of phosphorous and nitrogen eutrophication potentials to a multi-regional input-output approach to characterize the importance of overall consumption for marine and freshwater eutrophication across 44 countries and 5 rest-of-world regions over the period 2000-2011. We find that clothing, goods for shelter, services and other manufactured products account for 35% of global marine eutrophication and 38% of the global freshwater eutrophication footprints in 2011, up from 31 and 33%, respectively, in 2000. Relative to food consumption, non-food consumption is also significantly more income elastic and shaped by trade. As economies develop, this points to the need for trade agreements and policies to consider the displacement of ecosystem impacts. © 2018 The Author(s).
