58% of wildlife wiped out over last 40 years

If things don't change soon the ongoing decline is likely to reach two-thirds by the end of the decade.
The disturbing statistic was reported via a global biological diversity assessment conducted every two years by the World Wide Fund for Nature (WWF).

The study determined that animals living in lakes, rivers and wetlands were suffering the biggest losses, mostly due to pollution, habitat loss and climate change.
"It's pretty clear under 'business as usual' we will see continued declines in these wildlife populations," said Dr Mike Barrett, head of science and policy at the WWF.

"But I think now we've reached a point where there isn't really any excuse to let this carry on."

"We know what the causes are and we know the scale of the impact that humans are having on nature and on wildlife populations - it really is now down to us to act."

We are talking semantics here, since we basically both agree.    According to the sources cited by Wikipedia (yeah, I know, but the wiki looks well written)  Wiki   So actually it's the other way around, the Spanish flu was way more time limited than the Black Plague.    We can argue on the numbers, but humankind has been impacted.  Then of course it depends if you see it from a relative or absolute point of view. For sure the Black Death impacted way more harshly, killing around 50% of European population, while the SF "only" 3-6% (of world population), but if you look at the actual nu... [More]

Are we talking about the same thing?  Both epidemics had serious impacts on human populations.  BUT:  during the black death, there were fewer births (because there were fewer people to begin with), so it didn't require as many deaths to reduce human population.  The Spanish flu produced perhaps as many deaths, but there were more births (due to a larger base population), so the Spanish flu did not decrease human population. Once they're born, it is not hard to predict when they are going to die.  Predicting birth is the hard part. Which was the worse, depends on your POV. Doug

Apparently not!  I didn't want to start a contest between which was worse, but only to point out that the Black Death is not chronologically the last, there's the Spanish flu after it.    See it as you prefer, but a flu that kills at least 25 million people and makes more casualties than the just finished WWI to me is something.    Then, as I said, I won't argue on which was worst, that wasn't and still is not my point.

All I'm saying is that the Black Death caused human populations to decline, while the Spanish flu did not.  That doesn't say anything about which caused more deaths. BTW:  About 10% of Europeans have resistance to hemorrhagic fevers - virus diseases.  That gene appears to have originated about 700 years ago - the Black Death.  But the Black Death is a bacterial disease.  So how did a bacterium produce a gene that gives immunity to a virus?

Considering that the first wiped out 50% of European polulation (so for that time let's say it equals to around 35-40% of world polulation) while the second between 3 and 6% of world population, I'd say that's an understatement.    I have no idea, spontaneous generation?

We seem to be on the same wavelength here.  No need to split more hairs. Another Black Death mystery:  at the time of the Black Death, leprosy disappeared from Europe.  Suspicion that it wiped out all the lepers. Doug

I decided to look at the actual original report (I know, I know...why would I do that?) and found some interesting things. (Yeah and here's the link to the actual report - http://www.wwf.org.uk/sites/default/files/2016-10/LPR_2016_full report_spread low res.pdf?_ga=1.165145021.322127206.1478890768). First of all, the majority of LPI calculations are shown to be little more than blindfolded darts based on their confidence limits. And that's simply taking the data at face value - not critically assessing the methods used there. Second, it's just as darts-y looking at the data out of an example... [More]
