From the Summary: "Global trade in illegal wildlife is a growing illicit economy, estimated to be worth at least $5 billion and potentially in excess of $20 billion annually. Some of the most lucrative illicit wildlife commodities include tiger parts, caviar, elephant ivory, rhino horn, and exotic birds and reptiles. Demand for illegally obtained wildlife is ubiquitous, and some suspect that illicit demand is growing. […] The role of Congress in evaluating U.S. policy to combat wildlife trafficking is broad. Potential issues for Congress include (1) determining funding levels for U.S. wildlife trade inspection and investigation; (2) evaluating the effectiveness of U.S. foreign aid to combat wildlife trafficking; (3) developing ways to encourage private-sector involvement in regulating the wildlife trade; (4) using trade sanctions to penalize foreign countries with weak enforcement of wildlife laws; (5) incorporating wildlife trade provisions into free trade agreements; and (6) addressing the domestic and international demand for illegal wildlife through public awareness campaigns and non-governmental organization partnerships. This report focuses on the international trade in terrestrial fauna, largely excluding trade in illegal plants, including timber, and fish."
