Earth's Sixth Mass Extinction Already Underway
Scientists warn in a new study that Earth is undergoing a sixth mass extinction that is "more severe than perceived."
Not only that, human activity—including pollution, deforestation, overpopulation, poaching, warming oceans and extreme weather events tied to climate change—is to blame for this massive loss in biodiversity, according to an analysis published Monday in the Proceedings of the National Academy of Sciences.
For the study, researchers from Stanford University and the National Autonomous University of Mexico analyzed data on 27,600 species of birds, amphibians, mammals and reptiles, comprising nearly half of known terrestrial vertebrates.
The results were shocking—about one-third of the species decreased in population size and range. Even common species are in decline.
"We find that the rate of population loss in terrestrial vertebrates is extremely high—even in 'species of low concern,'" the authors wrote.
Ecologist Gerardo Ceballos, an author in of the study, explained to the Atlantic how barn swallows, for instance, still number in the millions but are declining in many parts of their range.
"Even these common species are declining," Ceballos said. "Eventually, they'll become endangered, and eventually they'll be extinct."
Furthermore, in a detailed study of 177 mammals, the scientists found that all of the mammals have lost at least 30 percent of their geographic ranges between 1900 and 2015. More than 40 percent of those mammals—including rhinos, orangutans, gorillas and many big cats—have seen the land they once roamed shrink by more than 80 percent.
Without mincing words, the scientists described Earth's ongoing loss of wildlife as "biological annihilation" that will have "negative cascading consequences on ecosystem functioning and services vital to sustaining civilization."
Earth has witnessed five mass extinctions in its geological past during which the majority of living species were wiped from existence. The most well-known and recent extinction killed the dinosaurs. But instead of a massive asteroid, volcanic activity or other natural causes kicking off such an event, researchers in the new study argue that humans are to blame.
"In the last few decades, habitat loss, overexploitation, invasive organisms, pollution, toxification, and more recently climate disruption, as well as the interactions among these factors, have led to the catastrophic declines in both the numbers and sizes of populations of both common and rare vertebrate species," the study stated.
"Several species of mammals that were relatively safe one or two decades ago are now endangered," such as cheetahs, lions and giraffes, it said.
Biologist Paul Ehrlich, one of the scientists in the study, told the Guardian that their paper serves as a serious warning to humanity's own survival.
"The serious warning in our paper needs to be heeded because civilization depends utterly on the plants, animals and microorganisms of Earth that supply it with essential ecosystem services ranging from crop pollination and protection to supplying food from the sea and maintaining a livable climate," he said.
"The time to act is very short," Ehrlich added. "It will, sadly, take a long time to humanely begin the population shrinkage required if civilization is to long survive, but much could be done on the consumption front and with 'band aids'—wildlife reserves, diversity protection laws—in the meantime."

The decades-long struggle for social and environmental justice in the Niger Delta continues, largely unseen by the wider world.
On Aug. 11, hundreds of people from the Niger Delta stormed the Belema flow station gas plant owned by Shell in the Rivers State region of the Delta. The plant transports crude oil to the Bonny Light export terminal, from where it is shipped overseas.
The National Academy of Sciences, Engineering and Medicine said in a statement the Interior Department has directed it to cease its study on the potential health risks for people living near surface coal mines in Central Appalachia.
The Interior Department, which committed more than $1 million to the study last year, has begun an agency-wide review of grants over $100,000 because of the "Department's changing budget situation."
California and North Carolina's electricity grids faced no disruptions during Monday's solar eclipse, which many saw as a test for the future when solar power will command a greater share of the energy mix.
"It bodes well for renewable energy on the grid during an event like this," said Eric Schmitt, a vice-president at California Independent System Operator that delivers most of the state's electricity.
By Thursday the Trump administration's project of dismantling the public domain will burst into full bloom when Interior Sec. Ryan Zinke announces a wholesale reversal of more than a century of public lands protection through presidential designation of national monuments under Antiquities Act of 1908.
Are you ready to watch the Great American Eclipse of 2017? Will you be in the path of totality? Do you have your safety glasses ready?
Well, however you decide to watch the solar eclipse today, NASA TV will be showing the "Eclipse Across America" with live video of the celestial event. The feed is already live with lots of handy information about today's unprecedented eclipse. So be sure to watch above.
"One out of three Americans lives within 50 miles of high-level nuclear waste, some of which, like Plutonium, is lethally dangerous and will be around for an incredible longtime," John Oliver explained last night on Last Week Tonight.
According to the Nuclear Energy Institute, there is more than 71,000 tons of nuclear waste stranded at 104 reactors. "It was a problem we should have solved in the 1980s," Oliver said, "much like a Rubik's Cube."
Despite years of using nuclear energy, the country still doesn't have a permanent facility for its storage, the comedian said. Oliver proposed what the U.S. really needs is some kind of "nuclear toilet."

As Trump's presidency spirals like a toxic vortex from one crisis to another, and with the global news media reacting to one venomous tweet after another, it is easy to miss the slow assault against science and the environment that continues below the radar.
The crisis for Trump could get a whole lot worse, with his ex-Chief of Staff, Steve Bannon, who was sacked last week, promising that he was "prepared to go to war with his adversaries in the White House."
