Prelude to global extinction: Human impact on Earth's animals

10 posts in this topic

In the first such global evaluation, biologists found more than 30 percent of all vertebrates have declining populations. They call for curbs on the basic drivers of these losses.

we are making a waste world

I for one refuse to worship an artificial human so called civilisation

Here is the paper 

 

Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines

 

http://www.pnas.org/content/early/2017/07/05/1704949114.full.pdf

 

what a mess  the human system of greed is making with nature

  • 30% of vertebrate species  have declining populations
  • 2 vertebrate species are lost every year
  • 1/2 the number of individual animals that once were alive have disappeared 
  • billions of animal populations are gone
  • from the analysis of the  IUCN red list  in a previous study  41% of amphibians and 26 % of mammals are at risk of extinction

  • the article  concludes that there are only about 20 to 30  years to reverse things, with all signs going towards  a   " ever more powerful assaults on biodiversity in the next two decades, painting a dismal picture of the future of life,including human life "

 

 

 

  • another study has come out and looks at the prospects for biodiversity for the next 50 years   ,please see 

  https://conservationaction.co.za/recent-news/mass-extinction-cards-humans-responsible/    

 

Their report has a link  to the study in NATURE  , you can read it on the screen but the PDF did not download for me , I find it much easier to read it printed , so I paid the access fee.

more is available

 

  • Increasing protected areas by 5 percent in strategic locations could boost biodiversity protection by a factor of three.

  • interesting article but the journal has an access fee

A  key earlier paper is  Has the Earth’s sixth mass extinction already arrived? by A Barnosky and others NATURE MARCH 2011

the writers are all from the University of California at Berkeley

 

their section of the university ,intergrative biology has placed  the full paper up  with open access at

for a popular article published by Paul Ehrlich  and an associate in THE CONVERSATION  please see  

 

The conspiracy of declining numbers, population fragmentation, inbreeding and reduced genetic variation can lead to a fatal ‘extinction vortex’. In this sense, our planet is currently accumulating a large extinction debt that must eventually be paid.”

Life has existed on Earth for roughly 3.7 billion years. During that time we know of five mass extinction events – dramatic episodes when many, if not most, life forms vanished in a geological heartbeat

 Things are not going well ,by 2100, oceans may hold enough carbon to launch mass extermination of species in future millennia

 

In the past 540 million years, the Earth has endured five mass extinction events, each involving processes that upended the normal cycling of carbon through the atmosphere and oceans. These globally fatal perturbations in carbon each unfolded over thousands to millions of years, and are coincident with the widespread extermination of marine species around the world.
