Giraffes Are in Trouble–the U.S. Endangered Species Act Can Help

The following essay is reprinted with permission from The Conversation, an online publication covering the latest research.

On April 19 of this year, five major wildlife protection groups petitioned the United States Fish and Wildlife Service to list the giraffe (Giraffa camelopardalis) as an endangered species. As the petition asserted, “the giraffe has suffered a major reduction in population size across its range primarily due to habitat loss, commercial overutilization, and severe poaching, and such decline continues unabated.”

If the Fish and Wildlife Service agrees to list the giraffe, a set of legal tools will become available to protect this iconic species. But how would listing in the U.S. help this African mammal, whose population numbers in the wild have dipped below 100,000?

Extinction is forever

While extinction can be a natural process, the current rate of extinction is anything but. Scientists estimate that at least 99 out of 100 species extinctions in the world today are the result of human action. Although people rarely intend to drive species into oblivion, as with the giraffe, they do so through the destruction of habitat, poaching and legal hunting. As the petition notes, “[g]iraffes once occupied much of the savanna and savanna woodlands of Africa…. [It] has undergone a 36 to 40 percent population decline over the past 30 years.”

More than a century ago, scientists began to notice the disappearance of once prominent species around the world. TheAmerican passenger pigeon, the Carolina parakeet and the Great Auk—once well-established in North America—disappeared. Other species like the American bison and many kinds of whales had once played central roles in important ecosystems but had been reduced to small remnant populations.

The existence of species is important to people for many reasons. Sometimes species provide clues for the development of medicines. Often they play a fundamental role in maintaining the…
