'Strong interactions' with predators

Here's your euphemism of the month, courtesy of a BBC science story headlined Big game 'could roam US plains'. Some scientists recommend restoring "mega fauna" to North America -- that's lions, elephants, and especially the cheetah:

Once, American cheetah (Acinonyx trumani) prowled the plains hunting pronghorn (Antilocapra americana) - an antelope-like animal found throughout the deserts of the American Southwest ... Their disappearance left glaring gaps in the complex web of interactions, upon which a healthy ecosystem depends. The pronghorn, for example, has lost its natural predator and only its startling speed -- of up to about 60mph -- hints at its now forgotten foe. By introducing living counterparts to the extinct animals, the researchers say, these voids could be filled. So, by introducing free-ranging African cheetahs to the Southwest, strong interactions with pronghorns could be restored, while providing cheetahs with a new habitat.

Emphasis mine. Yes, putting predatory cats and browsing herbivores in the same ecosystem may indeed restore strong interactions. Reminds me of the old all-purpose excuse my high school teachers had for not allowing us to break the dress code*: that long hair or other deviations from Leave-It-To-Beaver norms were "distracting." They, too, feared "strong interactions."

*Yes, I am really old. But I also saw the death of the dress code, in 1972.
