World's Vertebrate Population Dropped by an Average of 60 Percent Since 1970, WWF Says

"There cannot be a healthy, happy and prosperous future for people" without biodiversity, the report warns.

The population of the planet's vertebrates has dropped an average of 60 percent since 1970, according to a report by the WWF conservation organization.

The most striking decline in vertebrate population was in the tropics in South and Central America, with an 89 percent loss compared to 1970. Freshwater species have also significantly fallen — down 83 percent in that period.

The Living Planet Index, provided by the Zoological Society of London (ZSL) and included in the WWF Living Planet 2018 report, tracked the population of mammals, birds, fish, reptiles and amphibians around the world between 1970 and 2014, the latest year for which data was available.

Three-quarters of flying insects in nature reserves across Germany have vanished in 25 years, with serious implications for all life on Earth, scientists say

theguardian.com - by Darian Carrington - October 18, 2017

The abundance of flying insects has plunged by three-quarters over the past 25 years, according to a new study that has shocked scientists.

Insects are an integral part of life on Earth as both pollinators and prey for other wildlife and it was known that some species such as butterflies were declining. But the newly revealed scale of the losses to all insects has prompted warnings that the world is “on course for ecological Armageddon”, with profound impacts on human society.

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

Tue, 2017-07-11 22:01 — Kathy Gilbeaux

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

CLICK HERE - RESEARCH - PNAS - Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines

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” . . .

As Science publishes the updated research, four of nine planetary boundaries have been crossed: climate change, loss of biosphere integrity, land-system change, altered biogeochemical cycles (phosphorus and nitrogen). Image source: F. Pharand-Deschênes /Globaïa

Planetary Boundaries 2.0 – new and improved

As Science publishes the updated research, four of nine planetary boundaries have been crossed

Four of nine planetary boundaries have now been crossed as a result of human activity, says an international team of 18 researchers in the journal Science (16 January 2015). The four are: climate change, loss of biosphere integrity, land-system change, altered biogeochemical cycles (phosphorus and nitrogen).

New Report Reveals U.S. Fisheries Killing Thousands of Protected and Endangered Species

Wasted Catch: Unsolved Problems in U.S. Fisheries)

thedailybeast.com - by Abby Haglage - March 23, 2014

A new report by Oceana exposes nine U.S. fisheries that throw away half of what they catch, and kill dolphins, sea turtles, whales, and more in the process.

A new study released this week called Wasted Catch: Unsolved Bycatch Problems in U.S. Fisheries reveals the nine dirtiest fisheries in the United States. It’s a dirty bunch indeed, the waste between them accounting for nearly half a billion wasted seafood meals in the U.S. alone.

Culled by Oceana, the largest international organization for ocean conservation, the fisheries are ranked based on bycatch—the amount of unwanted creatures caught while commercial fishing.
