On this topic, I can never end recommending Adam Curtis's series "All Watched Over by Machines of Loving Grace", and on this topic of "bounce back" the second episode in that series.
The concept of "natural equilibrium" is a 1950s cybernetic machine fantasy projected onto the natural world rather than an accurate reflection of ecological reality. We can model the world in the language of system theory, but the models we make there might not have much to say about the real world. We can claim that from system theory it follows that there must be an equilibrium (as somewhat of an expert, I can say that even that is not true) and that if we disrupt the system, things will eventually go back to that equilibrium. And if we don't see it, we just needed to wait longer.
The whole stack of logic is not really build on any proper reasoning. The parallel with economics based on the "homo economicus" is striking, also there you reason from an ideal model and try to make inductive statements about the real world, which in many places directly conflict with observation. The "eco-system" and "natural equilibrium" stem from this approach of applying system theory to ecology, and are ideas which are now _very_ ingrained in western thinking, but which are obviously off.
A bit of caution with this line of thinking, because I was blindsided by it after more than decade of hand waving away "academics"
When you have the mind of "the models are wrong", you tend to be brought there by select counter examples, and in that space you only feed on counter examples. "The experts are wrong (and you can be right in 15 minutes if you consume this media!)" is abundant.
The actual reality is "the models work great until they don't". Not "the models don't work."
Ironically, the experts, the ones building the "wrong" models, tend to be the ones most aware of this. The "until they don't" part is also a pretty heavy mental burden for laymen to determine, hence much easier to just discredit the whole thing.
The "natural" state of the universe is having no life at all. And once our sun implodes this region of the universe will cease to be an exception.
Instead of trying to perform a balancing act with nature we should just continue to shape things into things that are more convenient to us. Like redirecting water into a desert.
I think what happened to the cod fishery off North America is really interesting. They overfished the cod then decided to regulate the fishery to let the population come back. But it never recovered - the cod population is stable but at a much lower number. Other 'stuff' (other fish species, jellyfish, etc) had moved into the environmental niche that the cod were in.
They never actually stopped fishing it though. It's regulated at a level to prevent 100% collapse, there was never political support to let it truly recover by banning fishing for a decade or two.
You don't even have to ban fishing entirely, just reduce the fishing to a point where fish populations increase. It might mean that fishing has to be at half the level it is now which still isn't great for the people impacted but you don't have to go 100% outright ban.
I had always assumed this, and my idea of nature bouncing back was more on the millions of years time scale as evolution would result in the refilling of empty ecological niches.
All that said I still think we should just extinct disease carrying mosquitoes.
There are differing views on evolution, between slow and gradual and punctual equilibrium( a sudden breakthrough that triggers a biological arms race), this article is looking more at the very short term and saying if a species goes extinct another species does not immediately or fully occupy the space...which I guess needs to be stated but I would think that it was already understood...
The article is more focused on oceanic and coastal diversity but I agree about the mosquitoes.
Yeah the news for me here is that people thought nature could "bounce back" on a human timescale. Any human lifespan is just the blink of an eye to nature
Nature is not harmonious, it is in constant flux. Saying it can bounce back implies there some state of equilibrium for it to bounce back to. I guess there's no reason why it can't bounce forward.
For anyone curious about what can be done about this, see the Kunming-Montreal Global Biodiversity Framework (GBF) adopted during COP15 by 188 countries - https://www.cbd.int/gbf
That was a pointless source. Which 23 categories? How do I know if I care about them?
Fig. 2 [1] lists them. Fig. 3 I think indicates that 20 of them have positive effect size on biodiversity, which I think was the point. "Learning and inspiration" is an interesting category. Carbon sequestration ranks high, with Terrestrial (as opposed to the larger Oceanic) having quite a few studies behind it.
This doesn't mean we shouldn't make every effort to re-wild places. It'll slow or even prevent the loss of at-risk species and introduce resilience to ecosystems against the onslaught of climate change.
I feel like we should do our best to not destroy the environment, for altruistic reasons but also for the very selfish reason that I have children and relatives with children so I want to leave them with a place they can live in and enjoy not a mess they have to deal with.
I think we have made great strides at saving some near extinct species, the kakapo for example, but we can do better.
Reading the title, I was ready to come in with arguments about the Cambrian explosion and different timescales, the article it's self however is not really talking about things along those lines, it is talking about the short(or very short) term where we assume that once species will easily take up a niche that was occupied by another if one goes extinct. Which I believe is looking at things on the wrong timescale, even if we assume punctuated equilibrium rather than gradual evolution.
Nature itself ain't in no long term stasis, its just us humans projecting our wishful thinking on our environment. Planet is warming since last ice age (ie all glaciers in the Alps are provably receding since 1850 when measurements started, and ie vineyard region where I live was provably under huge glacier some 25k years ago).
Often cited mosquito eradication (at least those transmitting malaria, dengue, yellow fever, zika and so on) would change few things even though most folks would not even notice... and I couldn't welcome it more intensively. These academic discussions in the west would quickly die off when people around you start dying frequently from these (especially small children, but also grandparents or just weaker / more unlucky folks).
Massive droughts this summer still continuing here where I live wreaked way more havoc not only in insect world than any such engineering would do, yet I see no violent mass protests all around the world about banning cars, huge transport ships or commercial & private jet flying for example, or some other big pollutants. Literal frog in boiling water situation.
We are in the 6th mass extinction event. Want to feel bad? Look at the numbers of decline in the last 40 years, it's dramatic. Even in my lifetime it's been dramatic.
I dont think its a big loss to the universe if humans go extinct. Humans didnt engineer the biochemistry of life or produce the atmosphere or the over rated buggy brain.
Did stream restoration for a few years and the thing that stuck with me is you can put the habitat back and the species still don't return. Some of them just have nowhere left to come from.

Humorous, but not inaccurate about what climate change means to primates. =3

Even letting aside any survival mechanism we have there are two rational posibilities:
1. We are alone in the universe => super huge loss of complexity and consciousness
2. We are not alone but at Universe scale intelligent life seems rather scarce => still huge loss in diversity
