This Map Shows How Your Consumption Habits Impact Wildlife Thousands of Miles Away

By Shreya Dasgupta

Global trade has made it easier to buy things. But our consumption habits often fuel threats to biodiversity—such as deforestation, overhunting and overfishing—thousands of miles away.


Now, scientists have mapped how major consuming countries drive threats to endangered species elsewhere. Such maps could be useful for finding the most efficient ways to protect critical areas important for biodiversity, the researchers suggest in a new study published in Nature Ecology & Evolution.

"Conservation measures must consider not just the point of impact, but also the consumer demand that ultimately drives resource use," the researchers wrote in the paper.

Researchers Daniel Moran of the Norwegian University of Science and Technology and Keiichiro Kanemoto of Shinshu University in Japan, identified 6,803 threatened species (species that are listed as vulnerable, endangered or critically endangered on the IUCN Red List) and pinpointed the commodities that contribute to various threats affecting those species. Then they traced the implicated commodities to their final consumers in 187 countries using a global trade model.

The resulting maps can tell which countries and which commodities, threaten species at the various hotspots, the researchers said.

For example, the maps show that commodities used in the U.S. and the European Union exert several threats on marine species in Southeast Asia, mainly due to overfishing, pollution and aquaculture. The U.S. also exerts pressure on hotspots off the Caribbean coast of Costa Rica and Nicaragua, and at the mouth of the Orinoco around Trinidad and Tobago. European Union's impacts extend to the islands around Madagascar: Réunion, Mauritius and the Seychelles.

The maps also revealed some unexpected linkages. For instance, the impact of U.S. consumption in Brazil appears to be much greater in southern Brazil (in the Brazilian Highlands where agriculture and grazing are extensive) than inside the Amazon basin, which receives a larger chunk of the attention. The U.S. also has high biodiversity footprint in southern Spain and Portugal, due to their impacts on threatened fish and bird species. These countries are rarely perceived as threat hotspots.

EU consumption is fueling threats in African countries like Morocco, Ethiopia, Madagascar and Zimbabwe. Similarly, consumption in Japan is driving threat hotspots in Southeast Asia, and around Colombo and southern Sri Lanka, where threats are linked to tea, rubber and other manufactured goods sent to Japan.

The researchers write that their maps can help connect conservationists, consumers, companies and governments to better target conservation actions. Companies, for example, can use the maps to see where their inputs are sourced and to reduce their biodiversity impacts. Conservationists, too, can use the maps to identify the intermediate and final consumers whose purchases sustain industries that threaten endangered species.

"Connecting observations of environmental problems to economic activity, that is the innovation here," Moran said in a statement. "Once you connect the environmental impact to a supply chain, then many people along the supply chain, not only producers, can participate in cleaning up that supply chain."

110 Million Americans May Be Drinking PFAS-Contaminated Water

More than 1,500 drinking water systems across the country may be contaminated with the nonstick chemicals PFOA and PFOS, and similar fluorine-based chemicals, a new EWG analysis shows. This groundbreaking finding comes the same day the U.S. Environmental Protection Agency (EPA) is convening a summit to address PFAS chemicals—a class of toxic chemicals that includes PFOA and PFOS, and that are linked to cancer, thyroid disease, weakened immunity and other health problems.

National Park Service Releases Climate Report That Officials Tried to Censor

The National Parks Service (NPS) quietly released a long-delayed report that mentions humanity's role in climate change, which officials had removed in earlier drafts.

The report, published Friday without a press release or any social media activity from the parks department or Interior Secretary Ryan Zinke, shows estimates of sea level change for 118 coastal national park sites and estimates of storm surge for 79 of the sites.

Will Gov. Brown Plug the Dangerous Hole in California’s Climate Action?

By Kelly Trout

California Gov. Jerry Brown is gearing up to host leaders from state, tribal, and local governments, business and citizens from around the world at a Global Climate Action Summit in San Francisco this September. His goal is to "inspire deeper commitments" in support of the Paris agreement goals. He has emphasized that, on climate, "so far the response is not adequate to the challenge" and "no nation or state is doing what they should be doing."

Alaska Airlines Launches #StrawlessSkies Campaign

As part of its worldwide push "For a Strawless Ocean," Alaska Airlines announced Monday that its 44 million yearly passengers will fly in "strawless skies."

Starting July 16, the leading U.S. airline on the 2017 Dow Jones Sustainability Index will stop distributing single-use plastic stirring straws and citrus picks in its lounges and on its domestic and international flights. It is the the first U.S. airline to do so. The non-recyclable items, which the airline distributed 22 million of last year, will be replaced with Forest Stewardship Council certified birch stirring sticks and bamboo citrus pickers.
