We are the next great mass extinction event and in some ways our impact is already faster (and this far in, harder) than most of our previous mass extinction events. But hey, billionaires need a few more yachts and need endless growth even if it literally kills the planet. So thats a price we are willing to pay for them. We should be rioting.

This is a famously difficult to interpret statistic. It's an excellent survey, but you probably do not understand what the number means (because it is a weird number). In particular, only half of species surveyed showed a population decline at all, the other half either grew or were stagnant.
The authors of the LPI go to great lengths to explain this. Yet, there is inevitably a long list of headlines claiming that we’ve “lost 73% of wildlife”, “73% of species have gone extinct”, or “73% of species are declining”. All of these are incorrect.
To give you another sense that this number is weird:
The 2022 Living Planet Index reported an average decline of 69% since 1970. In 2024, it reported a 73% decline. And this latest report finds the same: 73%.
So, what exactly is this 73% number?
To obtain the final LPI number, researchers take the geometric mean of the rates of change across all these populations. They also provide different weights to different populations, which affects the final result.
I don't know other places where I'd take the geometric mean. I have no intuition for it. So... caution advised.
Ok; I've thought through several examples. The geometric mean is heavily biased to show a decrease IMO. A species could have it's total population grow substantially, but if most of that growth is to already large/successful subsets, then it'll almost certainly show as a negative (geometric) average change, even with ~noise on the other populations. I think you should only see a positive metric here if most species measured are invasive; growing extremely fast in places not prepared for them. (and being careful not to measure the things getting killed by the new invaders)
....fuck. The Brazilian election going poorly isn't going to help. I suppose we won't know what the final nail looks like until after it happens (hindsight, and all that) but I feel like putting the Amazon in the hands of fascists could do it.
Yes. We're living a human driven mass extinction event and we're all going to starve.
I was just reading the report and was about to make a post

i wish people stopped calling it "human driven". it’s capitalism and colonialism driven. the sooner we realise this, the sooner we can put an end to it
capitalism and colonialism are both human.
It's all human. Even if capitalism and colonialism were off the table, every person alive consumes so much food a day, and every square foot devoted to their life is unavailable for wildlife.
we don’t have to do it in the most wasteful way tho
it shouldn’t be lost on us that the two first pictured examples on the wikipedia page for the anthropocene extinction are of the bison and dodo. two animals who coexisted with humans for thousands of years and were only driven to extinction (or near extinction) a very short time after a particular group of humans (read: european settlers) came
Agriculture isn't the main contributor to climate change and there are known solutions for reducing agricultural land-use like not eating meat. There is research on stuff like this and a sustainable global society of billions isn't some unachievable goal because of how much humans need to eat.
The people in charge benefit the most from capitalism, so it wont happen
Broader than capitalism; it's growth driven no? A planned economy that wanted a steady increase in energy/quality of life/resource extraction would also do most of this.
Boomers will also start a nuclear WW3 before they die off. This fucking pos generation leeched and destroyed and improvished and brought the whole planet down with them
