Global maps that show where the impact of consumer demand for wildlife is felt most strongly could help to guide conservation spending and priorities.
Daniel Moran at the Norwegian University of Science and Technology in Trondheim and Keiichiro Kanemoto at Shinshu University in Matsumoto, Japan, created the maps by combining data on where threatened species live with where the products made from them are eventually sold.
The maps show the areas most affected by consumption in different countries. For example, southeast Asia is a hotspot of threatened marine species that is linked to US consumption. For land animals, the US demand affects regions in southeast Asia and Madagascar, as well as southern Europe, Africa's Sahel region and parts of Mexico.
