Regulation

While government's Endangered Species Act has been a government-sized failure, private ownership saved the bison.

"Since Richard Nixon signed the comprehensive Endangered Species Act of 1973, intended to “halt and reverse the trend toward species extinction, whatever the cost” (emphasis added), only 30 of these 9,000 species have actually recovered, with ten having gone extinct. This gives the Act, enforced by both the U.S. Fish and Wildlife Service (FWS) and the National Oceanic and Atmospheric Administration (NOAA), an abysmal success rate of less than 1 percent despite an average yearly budget of nearly $2 billion.
