From Mongabay.com: "Researchers studying the impact of conservation actions since the landmark 1992 Rio Earth Summit say that at least 21 species of birds and seven mammals have been saved from extinction through direct human intervention."
It's all much more complex than that, of course. In the aftermath of a 1992 conservation conference called the Rio Earth Summit, which emphasized the need to prevent further loss of species, this story says human efforts have saved 21 birds and seven mammals from going extinct.
There is much, much more to do. We are in the middle of what some scientists call the Sixth Great Extinction in Earth history. We lose documented species at a rate of about one a year, but we're also losing species of plants and animals before they can even be found and named. So every success is something to celebrate.
