Earth's Sixth Mass Extinction Event Under Way, Scientists Warn

Researchers talk of ‘biological annihilation’ as study reveals billions of populations of animals have been lost in recent decades

           

Earth already in midst of sixth mass extinction, scientists say

theguardian.com - by Damian Carrington - July 10, 2017

A “biological annihilation” of wildlife in recent decades means a sixth mass extinction in Earth’s history is under way and is more severe than previously feared, according to research.

Scientists analysed both common and rare species and found billions of regional or local populations have been lost . . . 

 . . . “All signs point to ever more powerful assaults on biodiversity in the next two decades, painting a dismal picture of the future of life, including human life” . . .

Uptick in Creutzfeld-Jakob Cases Raises Questions

Is chronic wasting disease in deer making the jump to humans?

medpagetoday.com - by MedPage Today Staff - July 10, 2017

Cases of Creutzfeldt-Jakob disease, the fatal prion disease that's closely related to "mad cow" disease, have risen in Wisconsin and nationally in recent years, according to the Milwaukee Journal Sentinel.

In Wisconsin, there were six cases in 2002, but in two of the last four years, 13 cases have been reported -- which could be attributed to better surveillance, local officials said. Yet the increase tracks with data on chronic wasting disease among deer in the state, raising concerns about whether the illness is jumping from animals to humans.

Why Killer Viruses Are On The Rise

       

Once called the "Dutchmen" because of their large noses and large bellies, proboscis monkeys live only in Borneo. Ecosystems that have a lot of diverse animals, like this monkey, also tend to have a lot of diverse viruses.  Charles Ryan

The next troubling outbreak could come from a rain forest . . . And a big reason why: all the crazy animals that live here.

. . . Wild animals are now refugees. They have no home. So they come live in our backyards. They pee on our crops. Share our parks and playgrounds. Giving their viruses a chance to jump into us and make us sick.

"So it's really the human impact on the environment that's causing these viruses to jump into people," Olival says.

And cause an outbreak? I ask. Or a pandemic, says Olival.

Superbug Gene Found on Pig Farm

Evidence of resistance to a “last-resort” drug for antibiotic-resistant bacteria is discovered among farm animals for the first time.

the-scientist.com - by Ben Andrew Henry - December 7, 2016

Modern agriculture relies on antibiotics to shield livestock from disease, but widespread over-use of antibiotics has raised concerns over creating highly resistant “superbugs.” Researchers announced this week (December 5) that bacteria carrying a rare, dangerous gene for antibiotic resistance have been found in agricultural animals for the first time.

In a study published in Antimicrobial Agents and Chemotherapy, researchers took swabs and fecal samples from a pig farm and discovered bacteria resistant to carbapenems, an important class of antibiotics.

Climate Changing 'Too Fast' for Species

           

Tropical species are thought to be particularly vulnerable.  Thinkstock

CLICK HERE - STUDY - Rates of change in climatic niches in plant and animal populations are much slower than projected climate change

bbc.com - by Helen Briggs - November 23, 2016

Many species will not be able to adapt fast enough to survive climate change, say scientists.

A study of more than 50 plants and animals suggests their ability to adapt to changes in rainfall and temperature will be vastly outpaced by future climate change.

Amphibians, reptiles and plants are particularly vulnerable, according to US researchers.

And tropical species are at higher risk than those in temperate zones.

World on Track to Lose Two-Thirds of Wild Animals by 2020, Major Report Warns

Living Planet Index shows vertebrate populations are set to decline by 67% on 1970 levels unless urgent action is taken to reduce humanity’s impact

The number of wild animals living on Earth is set to fall by two-thirds by 2020, according to a new report, part of a mass extinction that is destroying the natural world upon which humanity depends.

The analysis, the most comprehensive to date, indicates that animal populations plummeted by 58% between 1970 and 2012, with losses on track to reach 67% by 2020. Researchers from WWF and the Zoological Society of London compiled the report from scientific data and found that the destruction of wild habitats, hunting and pollution were to blame.

Researchers Develop Model that Predicts Outbreaks of Zoonotic Diseases

Spatial distribution of simulated LAS spill-over events across its endemic region in western Africa for (a) present day, and (b) projected for 2070 under a medium climate and full land cover change scenario. Values represent the expected number of spill-over events per grid cell per year, and are represented on a linear color scale where green is all simulations and grey zero. Axis labels indicate degrees, in a World Geodetic System 84 projection. Filled black circles represent locations of historic LAS outbreaks.  Credit: Redding et al. UCL

sciencedaily.com - June 13, 2016

A model that predicts outbreaks of zoonotic diseases -- those originating in livestock or wildlife such as Ebola and Zika -- based on changes in climate, population growth and land use has been developed by a team of researchers.

Disease Evolution: How New Illnesses Emerge When We Change How We Live

Humans have been “acquiring” infectious diseases from animals (zoonotic diseases) since we first started hunting wild game on the African savannahs. Indeed, nearly 60% of bugs that infect humans originated in animals.
