Free Trade Can Save the Rhino

Is it possible that Michael Froman can succeed where both Leonardo DiCaprio and David Beckham have not? Maybe -- if the job is saving the rhino, whose population has dwindled to about 29,000 as poaching reaches record highs in countries such as South Africa.

As U.S. trade representative, Froman is the chief negotiator of the Trans-Pacific Partnership, a wide-ranging trade deal among the U.S. and 11 other nations that's expected to be completed this year. The benefits of the agreement will redound to the global economy, but they also extend to the rhino, the elephant and other species vulnerable to poaching.
