It just so happens I live in Eindoven, so I guess some more explaining is needed. They're working with the leafeblower now. I hate those contraptions so much.

As a fellow Eindhovenaar I hate the leaf blowers too!

We can't design a solution for the problem of 'too many humans devouring Earth's resources'. Locusts can't make plans. Galaxies cannot deviate from collision. I don't understand why we harbor fantasies about being anything other than a natural process that will simply run its course.

That's an interesting perspective. In many ways, it seems to me that evolution did not or cannot account for technological development. I have been trying to read more about what makes life go, and it seems it's highly related to thermodynamics and information theory. Are you proposing that any life will eventually discover technology (namely the ability to access and manipulate stored energy and also computation)? I…

Whatever we call technology is as natural a process as everything else systems in our Universe cobble together. I see no difference between termite mounds and the Internet. All is bound by the laws of physics. The same processes created complex monkey brains create datacenters. Physics is very clear: only things that are thermodinamically downhill can happen. Human civilization is just a natural, 4D phenomenon we get to see unfold. All in all it won't amount to more then any passing geological pattern on any planet before or since.

There is no salvation. Whatever was Earth before human civilization is in a death spiral. What comes next is anyone's guess. Elites are massing wealth to get off planet, and when the mass migrations really start and mid income countries start becoming failed states on their path, I hope you are in a place that can hold you safe for the remainder of your time here.

I believe that if we acted today, that there could be salvation. Institute massive taxes against plastic use. Ban it for take-out food and other single-use instances. Start heavily taxing other wasteful areas. Heavily encourage if not enforce composting and recycling. Immediately start restoring mowed lawns with native plants. Ban the use of chemical fertilizers. It could be done, but we won't. Salvation is at our fi…

If we ban chemical fertilizers (what does this include, btw?), will we be able to grow enough food to feed everyone? What else would have to change to make that possible?

I recently went back to my hometown in the USA after a couple of decades away. I was struck by how there we're almost none of the fireflies, grasshoppers and assorted other bugs I'd chased as a kid. I chalked it up to being a nostalgic old man, but I've never shaken that feeling that something is definitely not right.

Could be because you aren’t there in the grass and fields actively looking for them. If you garden and spend time in it, it’s amazing what you find.

I noticed it in my grandmother's backyard, so that variable was controlled. Then I noticed it pretty much in all my old haunts. Sample size N = 1, etc.

Aside from pesticides and land development, yet another cause of decline is our over obsession with landscaping and municipal lights (at least here in the Northeast US). I have mixed feelings about this: Night lights do add a bit of security, but insects such as moths rely on natural darkness and moonlight to navigate.

> another cause of decline is our over obsession with landscaping and municipal lights

Very much unlike their incandescent and florescent predecessors, LED lights emit practically no ultraviolet wavelengths, and therefore have a drastically reduced attractive effect on insects. Whatever effect outdoor lighting may have on insects, should be showing precipitous declines over the past several years, as LEDs have become the dominant artificial light source.

The last time this was discussed I found some articles showing that the more boxy and angular windows of older vehicles were less likely to have bugs smashed on them. This is why these studies often use license plate splatters to get a better count -- that really hasn't changed.

> some articles showing that the more boxy and angular windows of older vehicles were less likely to have bugs smashed on them Do you mean "more likely"? > This is why these studies often use license plate splatters to get a better count -- that really hasn't changed Do you claim the amount of license plate splatters remains consistent today as, say, 30 years ago, or some other time frame? I think this claim really n…

No, I absolutely meant "less likely". The bugs don't hit as often against the old vehicles. The older boxy vehicles were more likely to push the insect away, while the modern aerodynamic vehicles allowed the bug to hit the windshield more frequently. I'll see if I can find the study, I don't have it handy at the moment.

As for the license plates, they are no more aerodynamic than they were 30 years ago, which makes them a better source for insect measurement.

Wow, it's refreshing to see a Dutch person write down the impact of nitrogen as facts. Around me, its seems like slowly everyone is starting to doubt/deny the impact of nitrogen and whether it's something we need to care about. I'm starting to feel less at home in this country by the day because of it (and all the upside down flags consequently).

> Around me, its seems like slowly everyone is starting to doubt/deny the impact of nitrogen and whether it's something we need to care about. I'm not sure why that's surprising. Our food supply depends on using nitrogen at the moment. You can't just ban it cold-turkey without transitioning to an alternative that doesn't threaten the food supply. Particularly with inflation issues, further destabilizing the food supp…

> Our food supply depends on using nitrogen at the moment.

And it always will, since all plants require nitrogen for growing.

This article is pretty characteristic of the chemical industry influence trying to muddle the waters. I've watched recently a conference[1] by several renowned scientists. They affirm that neonicotinoids / neonics are responsible of at least 80% of the decline. They also affirm that the "merchants of doubt" are working their best to muddle the evidence with things like "there are multiple factors", "it's complicated"…

> But just like the overwhelming majority of lung cancer comes from smoking This is true. It's also true that less than 30% (in Europe as low as 15%) of smokers get lung cancer. [0] I point this out b/c I always believed that "if you smoke, you will get lung cancer" whereas the data was "if you get lung cancer, odds are it's from smoking" I wish that more information was presented this way but I also get that if your…

It is also true that this a 500fold increase in prevalence when compared to the general population.

The 5-year survival rate of lung cancer noticed due to e.g a sore throat is below 10%.

I can only comment on my neighborhood in the south SF bay area. Given that the region is a former home to orchards it doesn't surprise me that there is a lack of insects, but given the amount of trees/greenery vs my old SoCal neighborhood I can say that there is a startling lack of bugs here, with the exception of cockroaches(several varieties are disturbingly plentiful on the sidewalks at night), isopods/woodlice/pill bugs, and black widow spiders. Going on hikes in the Santa Cruz mountains, it also seemed like there were a shortage of insect life compared to hikes in SoCal.
