Meat-eaters are speeding worldwide species extinction

“To find out [how meat consumption impacted biodiversity], Brian Machovina and his colleagues looked at studies that identified the world’s biodiversity hotspots—those areas that contain the highest percentage of endemic plant and animal species. Most are located in tropical nations. Then, the researchers picked out countries that are most likely to expand their industrial livestock operations, and determined where and how much land will be lost to grazing and growing crops to feed livestock. Using data from the Food and Agriculture Organization and other studies about the production of cattle, pigs, and chickens in these countries from 1985 to 2013 and the amount of land the livestock required, they extrapolated the likely future expansion of agricultural lands. Finally, they created maps of overlap.

“Many of the places expected to see the greatest shift in land use from forest to livestock are in 15 “megadiverse” countries, which harbor the largest number of species, Machovina says. “By 2050, given current trends, these countries will likely increase the lands used for livestock production by 30% to 50%”—some 3,000,000 square kilometers—the researchers estimate.

“The habitat loss is so great that it will cause more extinctions than any other factor, the study notes, particularly when coupled with other deleterious effects of livestock production, including climate change and pollution. “These changes will have major, negative impacts on biodiversity,” Machovina says. “Many, many species will be lost.”  Sourced through Scoop.it from: news.sciencemag.org

GR:  Eventually all human “eaters” speed extinction.  Soybeans, wheat, and cabbages all require land to grow.  As the number of hungry humans grows, the amount of farmed land will grow.  If the coming massive storms do not reverse our growth, the loss of nature will.

Research shows catastrophic invertebrate extinction in Hawai’i and globally

“Hawai’i has been called the “extinction capital of the world.” But, with the exception of the islands’ birds, there has until now been no accurate assessment of the true level of this catastrophic loss. Invertebrates (insects, snails, spiders, etc.) constitute the vast majority of the species that make up Hawai’i’s formerly spectacularly diverse and unique biota. A team of researchers, including scientists from the Pacific Biosciences Research Center (PBRC) at the University of Hawai’i at Mānoa, the Bishop Museum in Honolulu, Howard University in Washington DC, and the French National Museum of Natural History in Paris, recently published the first rigorous assessment of extinction of invertebrates in Hawai`i.

“We showed, based on extrapolation from a random sample of land snail species from all over the world, and via two independent approaches, that we may already have lost 7 percent (130,000 extinctions) of all the animal species on Earth,” said Robert Cowie, research professor at PBRC and co-author of the two studies.”  Sourced through Scoop.it from: www.eurekalert.org

GR:  During human recorded history, world-wide extinctions may have already reached 7%.  For many groups, moths for instance, we have no analyses of extinction rates.

Stopping human-caused extinction of Earth’s plant and animal species is the greatest challenge of our time. This post provides access to the latest articles on extinction. The first item (Ceballos et al. 2015) is the latest detailed report on what we know and how we acquired the information.

Causes of Extinction

My blog covers the things that people do to cause extinctions and reduce biodiversity. These deeds of ours are woven into individual and our collective habits and beliefs. Stopping them will alter our society and our culture. It will be difficult. Our population must be reduced, our food choices must change, and our resource harvest must decline. Nothing less will succeed.

Climate change will become the major cause of extinction.  Here’s its search link on my blog:  Climate Change.

Fate of the Crowfoot Valley Prairie Dog Colony

by Deanna Meyer, Deep Green Resistance, Colorado.  When we visited the Crowfoot site to confirm the mass annihilation of the last large colony of prairie dogs in the Castle Rock area, we found that all the burrows were packed hard as concrete. I tried to shovel out the burrows but could not because they were …

Eleven new species found in Madagascar

Madagascar is home to extraordinary biodiversity, but in the past few decades, the island’s forests and associated biodiversity have been under greater attack than ever.  Source: phys.org

GR:  The Wildlife Conservation Society and others such as those listed by the Lemur Conservation Network are working within Madagascar to preserve wildlife.  However, as elsewhere, those who wish to harvest the land have power and influence.  Perhaps we should all visit, spend a little money, and express our concern.

CDFW celebrates “Endangered Species Day” as it hastens species extinction : Indybay

You just can’t make this stuff up – a government agency like the California Department of Fish and Wildlife “celebrating” National Endangered Species Day when it appears to be doing everything it can to benefit agribusiness and other corporate interests at the expense of endangered species, along with a host of fish and wildlife species not formally listed under the federal and state Endangered Species Acts!  Source: www.indybay.org

GR:  Government hypocrisy?  It’s the money, of course.  Most politicians and many government employees seek public office for personal gain.  They do what they can to associate with money and influence.

‘Urgent’ crowdfunding campaign hopes to help save three native Australian birds

“An international campaign begins to help save three native parrots at risk of extinction.

“The swift parrot, forty-spotted pardalote and orange-bellied parrot are all Australian native birds under threat from predatory sugar gliders.

“The swift parrot breeds in Tasmania during spring and summer, nesting in old trees with hollows.

“They migrate to south-eastern Australia during the cooler months, but many are not surviving long enough to make the journey.

“Logging in Tasmania has meant the tiny birds share their breeding habitat with sugar gliders.”

Source: www.abc.net.au

GR:  Logging and consequent habitat loss have forced competition among bird species that is driving these three toward extinction.  Money is needed to erect nest boxes on offshore islands so numbers can climb.
