The things we consume, from iPhones to cars to IKEA furniture, have costs that go well beyond their purchase price. What if the soybeans used to make that tofu you ate last night were grown in fields that were hewn out of tropical rainforests? Or if that tee-shirt you bought came from an industrial area that had been carved out of high-value habitat in Malaysia?

Unless you buy sustainably sourced food or goods, however, it can be hard to know just how consumer purchases affect species — until now. Daniel Moran from the Norwegian University of Science and Technology and his colleague Keiichiro Kanemoto from Shinshu University in Japan have developed a technique that allows them to identify threats to wildlife caused by the global supply chains that fuel our consumption. They’ve used this technique to create a series of world maps that show the species threat hotspots across the globe for individual countries.

Their article describing this effort has been published online in Nature Ecology & Evolution this week.
