Biological Annihilation: Earth's Sixth Mass Extinction Event is Under Way



We're killing everything off and destroying gods creation. How sad.

You really do fall for every lie you are told don't you? A mass extinction event is defined as an event in which more than half of species die...earth is estimated to have about 8.7 million species...half would put the number of species going extinct at about 4.35 million. My bet is that you can't name 30 species that have gone extinct, or endangered in the past 50 years that aren't due to over hunting. In case you were wondering...even if you can manage to name 30, that is a far far cry from 4.35 million.

In short, stop waving your hands hysterically...we are not in a mass extinction event....you have been lied to and sadly, you fell for it.

Abstract
The oft-repeated claim that Earth’s biota is entering a sixth “mass extinction” depends on clearly demonstrating that current extinction rates are far above the “background” rates prevailing between the five previous mass extinctions. Earlier estimates of extinction rates have been criticized for using assumptions that might overestimate the severity of the extinction crisis. We assess, using extremely conservative assumptions, whether human activities are causing a mass extinction. First, we use a recent estimate of a background rate of 2 mammal extinctions per 10,000 species per 100 years (that is, 2 E/MSY), which is twice as high as widely used previous estimates. We then compare this rate with the current rate of mammal and vertebrate extinctions. The latter is conservatively low because listing a species as extinct requires meeting stringent criteria. Even under our assumptions, which would tend to minimize evidence of an incipient mass extinction, the average rate of vertebrate species loss over the last century is up to 100 times higher than the background rate. Under the 2 E/MSY background rate, the number of species that have gone extinct in the last century would have taken, depending on the vertebrate taxon, between 800 and 10,000 years to disappear. These estimates reveal an exceptionally rapid loss of biodiversity over the last few centuries, indicating that a sixth mass extinction is already under way. Averting a dramatic decay of biodiversity and the subsequent loss of ecosystem services is still possible through intensified conservation efforts, but that window of opportunity is rapidly closing.

Palaeontologists characterize mass extinctions as times when the Earth loses more than three-quarters of its species in a geologically short interval, as has happened only five times in the past 540 million years or so. Biologists now suggest that a sixth mass extinction may be under way, given the known species losses over the past few centuries and millennia. Here we review how differences between fossil and modern data and the addition of recently available palaeontological information influence our understanding of the current extinction crisis. Our results confirm that current extinction rates are higher than would be expected from the fossil record, highlighting the need for effective conservation measures.

Are we in the midst of the sixth mass extinction? A view from the world of amphibians

1. David B. Wake*,† and
2. Vance T. Vredenburg*,‡

Abstract
Many scientists argue that we are either entering or in the midst of the sixth great mass extinction. Intense human pressure, both direct and indirect, is having profound effects on natural environments. The amphibians—frogs, salamanders, and caecilians—may be the only major group currently at risk globally. A detailed worldwide assessment and subsequent updates show that one-third or more of the 6,300 species are threatened with extinction. This trend is likely to accelerate because most amphibians occur in the tropics and have small geographic ranges that make them susceptible to extinction. The increasing pressure from habitat destruction and climate change is likely to have major impacts on narrowly adapted and distributed species. We show that salamanders on tropical mountains are particularly at risk. A new and significant threat to amphibians is a virulent, emerging infectious disease, chytridiomycosis, which appears to be globally distributed, and its effects may be exacerbated by global warming. This disease, which is caused by a fungal pathogen and implicated in serious declines and extinctions of >200 species of amphibians, poses the greatest threat to biodiversity of any known disease. Our data for frogs in the Sierra Nevada of California show that the fungus is having a devastating impact on native species, already weakened by the effects of pollution and introduced predators. A general message from amphibians is that we may have little time to stave off a potential mass extinction.

The sixth mass extinction: Anthropocene and the human impact on biodiversity


Abstract
Mass extinctions are a major pattern in macroevolution. Because of their frequency, quickness and global effects, they shaped the global biodiversity several times during the geological ages. As an integrative factor with respect to microevolutionary Neo-Darwinian processes, mass extinctions are probably due to a set of different possible causes (basaltic super-eruptions, impacts of asteroids, global climate changes, continent drifts, and so on). An analogy has been proposed. If we compare the rates and amounts of extinction during those singular evolutionary events with the range of species losses over the past few centuries and millennia in human times, we see a similar trend. Then, according to a group of authoritative evolutionists like Edward O. Wilson and Niles Eldredge, we have evidence that humans are now causing the so called “Sixth Mass Extinction”. “Anthropocene” also means that Homo sapiens has become a dominant evolutionary force. Through a mix of different significantly impacting activities (i.e., fragmentation of habitats, overpopulation, chemical pollution, invasive species, over-exploitation of resources in hunting and fishing), we have produced the conditions for a serious extinction crisis. According to Nature (March 2011), the sixth mass extinction is under way: “we find that Earth could reach that extreme within just a few centuries if current threats to many species are not alleviated” (Barnosky et al. 2011). We discuss here a recent model for mass extinctions (the “Perfect Storm Model”), based on the idea that these macroevolutionary patterns could be produced by a mix of three main simultaneous causes and conditions.

Yes, the scientists agree that there is a major extinction event under way, one which we are responsible.

What a bunch of dupes. You people crack me up and would be laughable if there weren't so many idiots out there that believe you actually have a clue.

I have asked you wackjobs to just name 30 species that have gone extinct for reasons other than over hunting...and you can't even do that and yet, you wave your hands like hysterical women and claim that the mass extinction is underway...what idiots...and I mean that in the nicest way possible.

What a dupe. I asked for 30 speices that had gone extinct for reasons other than over hunting...you provide 25 in the past 100 years and most of those are extinct due to overhunting...

A mass extinction is defined as an event that kills off over half the species of a planet...there are estimated to be 8.7 million species on this planet. If there were a mass extinction happening, you wouldn't have any trouble producing literally millions of species going extinct for reasons other than over hunting...while it is unfortunate that our ancestors didn't conserve as well as they should have, 25 species going extinct due to over hunting in 100 years is hardly an extinction event. Words have meanings.

Hey...its the spelling police. Find any punctuation errors? You guys are dupes...wackos...idiots. Mass extinction events are defined as events where half of the species on the planet go extinct...that would be something like 4.3 million species. You guys can't come up with even 30...and what you do find are mostly due to overhunting or over fishing...you are hand waving hysterics who believe whatever bullshit you are told and then go about crying that the sky is falling without the first actual clue...you are known by the people who feed you this bullshit as useful idiots..

Shit for a brain...Hunting is one of the main causes of extinction from humans. This is the number one reason for human caused extinctions.

If you're going to exclude it then you're a fool. You're too much of a ***** to admit that human hunting is killing everything on this planet!

LOL you dumbfuck.
Hunting will cause a mass extinction? How long will it take to kill off another 4.5M species? How many new species will pop up before then? Dont we discover around a 1,000 new species EVERY YEAR?
Mother fuckers better load their ARs a little faster!

Yes most species that have gone extinct in the past 500 years have been due to hunting....your OP, however makes the claim that we are in a mass extinction, which is not due to us hunting a few species into extinction...the claim is that climate change has brought on the next mass extinction. Clearly the OP is bullshit...practically every species you name is extinct due to hunting. Not one due to climate change which is the claim of the OP...so yes, you have been duped, and are playing the part of a useful idiot by perpetuating the lie.

And probably 35%+ of my list is about animals that went extinct for reasons other then hunting. But yes, keep on hunting and wiping out everything on this planet. Sick fuckers.
