When people think of wildlife trade, they often picture smugglers sneaking in rare and endangered species from far-off countries. Yet most wildlife trade is actually legal, and the United States is one of the world’s biggest wildlife importers.
New research that we and a team of colleagues published in the Proceedings of the National Academy of Sciences shows that, over the last 22 years, people in the U.S. legally imported nearly 2.85 billion individual animals representing almost 30,000 species.
