Humanity has wiped out 60% of animal populations since 1970

Okay so 7% is supposed to be a result of climate change.

No, the link goes to the MSN news homepage, because they've changed the url. It's just that Trump is busy making news as usual.
Here's the updated link:
Species that have gone extinct in our lifetime
Tested this one and it works.

That 60% is an average btw. It's doesn't mean humans have wiped out exactly 60% of animals.
Here's a link to an article in The Atlantic which explains it.
Have we really killed 60% of animals
Here's a link to an article in The Atlantic which explains it.
Quote:
Ultimately, they found that from 1970 to 2014, the size of vertebrate populations has declined by 60 percent on average. That is absolutely not the same as saying that humans have culled 60 percent of animals—a distinction that the report’s technical supplement explicitly states. “It is not a census of all wildlife but reports how wildlife populations have changed in size,” the authors write.
To understand the distinction, imagine you have three populations: 5,000 lions, 500 tigers, and 50 bears. Four decades later, you have just 4,500 lions, 100 tigers, and five bears (oh my). Those three populations have declined by 10 percent, 80 percent, and 90 percent, respectively—which means an average decline of 60 percent. But the total number of actual animals has gone down from 5,550 to 4,605, which is a decline of just 17 percent.

Have we really killed 60% of animals
Well stated!
And from elsewhere in the same article:
Quote:
None of this is to let humanity off the hook. Since prehistory, humans have killed off so many species of mammals that it would take 3 million to 7 million years of evolution for them to evolve an equivalent amount of diversity. At least a third of amphibians face extinction, thanks to climate change, habitat loss, and an apocalyptic killer fungus. Even invertebrates aren’t off the hook. There might be fewer data for them, but the data that exist paint an alarming picture of rapidly disappearing insects, even in supposedly pristine forests. Meanwhile, in the oceans, coral reefs are bleaching too quickly to recover: Half of the corals in the Great Barrier Reef have died since 2016. All this evidence points to a period of “biological annihilation” that some have likened to the five great mass extinctions of the past. When the reality is this sensational, there’s not much need to sensationalize it even further.
That's why we need to do something about mass immigration. The world's population is getting out of control.

How rare were those subspecies to begin with?
The way that the human-caused extinction process usually works, Ezra, is that a species goes into decline, becomes endangered, becomes critically endangered and then goes extinct. So naturally they were "rare" just before they became extinct. So the answer to your question is a simple matter of critical thinking.

I won't laugh 100% at that comment, because after all it's theoretically possible that mass immigration could contribute to a substantial loss of animal populations. If a million people on their way to a new home walk past a particular habitat and each one takes out a member of a species, then, yes, that would reduce and maybe even eliminate its population.
But until I see evidence that mass immigration actually does have a substantial impact on animal populations, I'll still be laughing 99+%.
I think it's safe to say that most human-based extinctions are caused not by immigration, but by stay-at-home people.
Like the ongoing annual bird massacre:

Because a subspecies can represent a tiny percentage of the entire species. Some subspecies are so rare they barely exist and are the result of a rare mutation or a fluke.

It has a crazy impact. When you flood people in from the third world who live more with nature and then chop trees down and replace fields with concrete and tarmac so you end up building millions and millions of houses, you destroy plenty of nature.
Then you have less room for houses so you start building houses that are more closed in with tiny gardens then you end up working towards the extinction of hedgehogs that trace back millions of years. But best not to think about mass immigration cause it's best not to be called a racist.
