There is no longer any doubt: We are entering a mass extinction that threatens humanity’s existence.
That is the bad news at the center of a new study by a group of scientists including Paul Ehrlich, the Bing Professor of Population Studies in biology and a senior fellow at the Stanford Woods Institute for the Environment. Ehrlich and his co-authors call for fast action to conserve threatened species, populations and habitat, but warn that the window of opportunity is rapidly closing.
“[The study] shows without any significant doubt that we are now entering the sixth great mass extinction event,” Ehrlich said.
Although most well known for his positions on human population, Ehrlich has done extensive work on extinctions going back to his 1981 book, Extinction: The Causes and Consequences of the Disappearance of Species. He has long tied his work on coevolution, on racial, gender and economic justice, and on nuclear winter with the issue of wildlife populations and species loss. Read more »

A review of large-scale studies involving more than 1.5 million people found all-cause mortality is higher for those who eat meat, particularly red or processed meat, on a daily basis. Conducted by physicians from Mayo Clinic in Arizona, “Is Meat Killing Us?” was published today in the Journal of the American Osteopathic Association. Read more »
A study of the content of rare earth elements in U.S. coal ashes shows that coal mined from the Appalachian Mountains could be the proverbial golden goose for hard-to-find materials critical to clean energy and other emerging technologies.
In the wake of a 2014 coal ash spill into North Carolina’s Dan River from a ruptured Duke Energy drainage pipe, the question of what to do with the nation’s aging retention ponds and future coal ash waste has been a highly contested topic.
One particularly entrepreneurial idea is to extract so-called “critical” rare earth elements such as neodymium, europium, terbium, dysprosium, yttrium and erbium from the burned coal. The Department of Energy has identified these globally scarce metals as a priority for their uses in clean energy and other emerging technologies. But exactly how much of these elements are contained in different sources of coal ash in the U.S. had never been explored. Read more »
