Biologists say half of all species could be extinct by end of century

I'm escaping from bathrooms and gender wars to get to a very important crisis that will no doubt be ignored by the majority...as it is elsewhere in society, but needs to be put forth anyway:

theguardian.com
Biologists say half of all species could be extinct by end of century
Robin McKie

One in five species on Earth now faces extinction, and that will rise to 50% by the end of the century unless urgent action is taken. That is the stark view of the world’s leading biologists, ecologists and economists who will gather on Monday to determine the social and economic changes needed to save the planet’s biosphere.

“The living fabric of the world is slipping through our fingers without our showing much sign of caring,” say the organisers of the Biological Extinction conference held at the Vatican this week.

Threatened creatures such as the tiger or rhino may make occasional headlines, but little attention is paid to the eradication of most other life forms, they argue. But as the conference will hear, these animals and plants provide us with our food and medicine. They purify our water and air while also absorbing carbon emissions from our cars and factories, regenerating soil, and providing us with aesthetic inspiration....................................
https://www.theguardian.com/environm...can-conference

This is even worse than the Guardian presents here with its kid glove treatment, since extinctions and near extinctions of other animals and plants means a mass reduction of biota...most of which we don't even understand exactly how it contributes to the running and management of necessary ecological cycles. As co-creator of the Gaia Hypothesis - James Lovelock said back in the 70's, we don't understand how important they are until after they're gone!

Many issues including/but NOT exclusively rapid global warming, are contributing factors to this mass extinction event that hardly anyone takes notice of, even though each new report has to be revised upwards on the rates of extinction and how far it will go in the future.

It's just too bad that 'the future' is always only as far as the end of this century, because the conditions driving the Sixth Mass Extinction are not going to stop at the start of the 22nd century!

This Guardian piece notes unnecessary controversies that arise when experts include those who comment on contributing factors that most of the world hasn't been willing to take a look at in years - human population growth presented by Paul Ehrlich. Ehrlich's primary concerns have long been how much of the common biosphere we each consume as we 'modernize' and how much of total natural ecosystems have to be lost to provide more for the growing human population.

We live in a magical time when almost all sides of big environmental issues are living in denial, if they can't find a way to even look at the obvious fact that our planet's human population is already many times larger than the planet's resources can sustain permanently! The only reason we don't have mass famine and mass starvation right now is because oil-based chemical fertilizers, mined phosphates, destruction of natural habitats and overdrawing underground reserves of freshwater allow this kind of food production to continue for a short time. When the time of reckoning happens....and it will happen...there is no techno-fix out of this jam when most of the food-growing zones' topsoil is used up, then comes a crash with the almost never mentioned final consequence..the end of the human race as well. This...what they're calling 'The Anthropocene' won't last very long one way or another, and it won't be the first time in Planet Earth's history that an overwhelmingly successful and dominant lifeform was completely wiped out when conditions changed during a mass extinction....look up 'Trilobites' as a good reference point.

Now, lets apply that scenario to overpopulating the US. The retarded Liberals and RINO's have no problem with taxing our own recourses into failure. Because, golly-gee, we're a nation of immigrants with unlimited recourse and jobs.
Thanks from webguy4 and Sabcat

I recall a renowned paleontologist several years back who specifically was studying and looking for fossil remains in the Cretaceous-Tertiary Extinction time period, comment that one of the last major dinosaur finds in West Texas was two dinosaur predators who, with lots of dead bodies around, decided instead to have a fight to the death, since the two were hardwired to be bitter enemies of each other.....so I'm thinking that there will be lots of likeminded dinosaurs around during the coming extinction fighting about taxes and killing immigrants as the human race goes extinct!
Thanks from imaginethat and Daws77

Cretaceous-Tertiary Extinction time period: Would that be the time period animals were fighting over very limited resources to survive? Catastrophe or over-population, the result is the same.

no it was about the time the asteroid bashed in to what would be Mexico.

That would have been post asteroid. Which is what we're discussing. Try to catch up.

false ! Most all large animals at that time died within hours or days after the event.
Mostly from asphyxiation.
Thanks again for showcasing your ignorance.



Fossil Record
A gradual decline in the number of dinosaur species would likely mirror an equally gradual cause of their ultimate extinction. Conversely, a sudden "now you see them, now you don't" end to the dinosaurs implies a catastrophic cause. Depending on location and interpretation, the fossil record seems to say different things.

Some paleontologists see evidence in the fossil record that dinosaurs were doing quite well prior to the end of the Cretaceous -- that they were in no way declining in abundance when the impact occurred.

Evolution: Extinction: What Killed the Dinosaurs?
Yeah, you empty nut-sack! It's called "post" catastrophe because it happen "AFTER"!!

That's usually what happens after a civilization collapses and they have no state powers to back them any longer. It's what David Rockefeller is trying to warn his more aggressive younger colleagues at the annual Masters of the Universe conferences.
