Years ago, my family used to drive to our grandparents' village in hot, summer Friday nights.
The windshield ended so pestered with dead bugs that the first task on Saturday morning was to drive the car to the river to clean it. I remember it vividly because it was so fun to wash the car with the cold river water.
Last August I went stargazing with my wife. We chose a secluded area because it was far away from light pollution, a few hours away from the capital.
We watched the Perseids for a couple of hours in the middle of a field. We had no lights on, but being CO2-emitting mammals, no flying insect bothered us. We had anti-mosquito spray ready but we didn't need to use it. There were a few ants but that's it.
Afterwards, I drove an hour and a half at 2am and only a few bugs died on my windshield. I didn't even need to use the wipers the next morning.
I hate mosquitoes as much as everybody else, but something has been happening to insects in the last 20 years. As a human it's comfortable but I'm honestly a bit afraid for the environment. And studies like this don't paint a positive picture.
It's such a minor thing when it comes to our day to day but becomes truly terrifying when you put it all together and look at the big picture. I've noticed the same thing about wild-life in general whenever I visit my favorite places from childhood - whether it's the reefs around Australia, the tide pools in Baja, or the inland empire desert I grew up in. Looking at actual research just makes it worse: a third of microorganisms in the upper marine layer have died off from pollution, almost all species considered keystone predators are gone or going extinct, and the climate is jumping off a cliff.
At first I thought it was an effect of aging (changes in nostalgia and awareness) but after moving back to one of the cities I lived in and talking to the local bird watching society, it seems to be happening everywhere on massive scales.
Climate changing power, without the wisdom to wield it, is as plausible a Great Filter as anything.
Hard to develop a space program when you're spending all your production fighting over scarce resources, plugging leaks, and attempting to feed a planet with decreasing yields.
I had two daughters before I came to the conclusion that this is the most likely path for humanity at this point. There is a possibility of a global awakening that might prevent this tragic loss of megafauna. But I'm already a vegan and don't drive much; can't think of more to do, and while I'm not too bad at dealing with this, it can be quite depressing.
That's barely the tip of the iceberg of what to do.
Public transportation or bicycling, avoiding one-time non-consumable items (one-time plates, forks, cups, cup-lids, straws, etc. are an absolute no-go—which means boycutting starbucks and similar if necessary), recycling, rallying against use of polluting materials (less polypropylene and soft plastic packaging in super-markets, for example), less materialistic imports (container ships use the nastiest oils to operate, as international waters have no emission regulations), thinking of ways to make being environmentally friendly simpler, etc.
And even more importantly, getting others to do the same. The difference from one person doing all this right will just be a drop of water in the ocean. If it does not spread, it does not matter.
Also, as someone who cares about the environment, I would suggest not putting vegan up front as your efforts. Regardless of cause or effect, "vegan" carries a stigma. "Vegetarian" communicates what is needed if the idea is to reduce pollution from cattle farming, and it is less likely to cause instant dismissal.
And, also, while replacing meat with vegetable farming has fewer gas emissions than cattle farming, that still does not deal with our farming techniques being unsustainable, or that many types of farming causing massive deforestation (soy, anyone?). Nor does it reduce massive oil pollution, stop the oceans from filling with microplastics, etc.
It's but one small thing on a very long list of things we need to fix.
There are some recent studies suggesting that globally, on average, the most environmentally friendly diets have some animal product component because of their ability to make use of landmass that we wouldn't be able to make use of directly. E.g., cattle can eat plants that grow in areas we can't grow human-friendly crops on.
I can't find citations to these studies offhand unfortunately. (this is an example but not what I had in mind: www.ncbi.nlm.nih.gov/pmc/articles/PMC5522483/) But what I remember is that globally, the most environmentally friendly diets had some small animal product component.
This also probably varies a lot by location too, so it probably is the case that for some people, the best diet might be vegan; for others it might involve more animal product.
Just pointing this out, because there are nonpolitical-psychological-sociological reasons for a "soft" approach on plant-based-diets.
I think a key component here is just minimizing the meat-component of the diet.
Meat would not at all be a problem if produced in smaller amounts. The current level is just absurd waste (I would guess mostly to support fast-food production?), and we absolutely do not need this amount of meat in our diet.
It is, however, extremely nutritious, so a small meat consumption would both be sufficient and much more sustainable. Even just 1/10th of the current scale would likely reduce any problems to be insignificant.
This is true, but from what I've read it is only true for places that are small scale and local. Anything large scale, like feeding a city, would benefit greatly from a reduction, or elimination, of animal products.
Something like 75% of all non-meat food grown in the US is fed to animals for later eating. When you complain about soy destroying forests, you are complaining about meat consumption:
> Just over 70 percent of the soybeans grown in the United States are used for animal feed, with poultry being the number one livestock sector consuming soybeans, followed by hogs, dairy, beef and aquaculture. The second largest market for U.S. soybeans is for production of foods for human consumption, like salad oil or frying oil, which uses about 15 percent of U.S. soybeans. A distant third market for soybeans is biodiesel, using only about 5 percent of the U.S. soybean crop. In 2013, soybean exports reached record highs, exporting 43 million metric tons to overseas markets. China remains the largest export market for U.S. soybeans.
You'll find this same thing over and over again when discussing clearing land for crop growth. The vast majority of it is to support meat production. Going vegan is probably the number one thing you can do to fight climate change and pollution in general, as an individual. Especially since switching would eliminate vast amounts of farming, and the associated chemicals and water loss. edit: and deforestation.
It is not a small thing, not at all, and to diminish it is to deny the massive sea of change that is required to actually fight climate change with 7B people on the planet.
Sure, there is a lot of cultural blowback against veganism, but I think it is manufactured via marketing, just like the anemic belief in climate change in the United States.
1. You mean "going vegetarian". Going vegan is something entirely different, and entirely unnecessary in this context.
2. Food is being massively overproduced, so a few thousand people boycutting meat is unlikely to even remotely affect the production amount, thus having no difference at all. A much bigger difference would be made by trying to fight food waste. Fight profit-optimization by over-production, go for local sellers rather than supermarkets with absurd over-stocking, etc.
3. You don't need to boycut meat to solve that problem. Just reduce it. From what I've read, the US consumes absurd amounts of meat, which fuels a giant meat production industry. If you cut the average meat consumption in half in the US, the meat industry would no longer be the primary consumer.
Meat itself is not to blame for the absurd over-production and over-consumption we see today. It is instead a result of the usual corporate greed, profit optimization, and our total ignorance for the side-effects of our convenience. Vegetarianism is entirely symptomatic treatment, rather than dealing with the root-cause.
(For the record, I respect the choice to not eat meat for other reasons, but I am only considering the environmental impact here.)
`. I don't mean "going vegetarian". I mean "going vegan". Milk, eggs, and fish have some of the same problems environmentally and ethically. When I say ethically, I don't just mean our responsibility not to bring harm to other species on the planet, although I feel that is important, but also our responsibility to future generations.
2. Yes, food is overproduced. Yes, too much food gets thrown away. However, this is massively dwarfed by the wasted food that we feed in animal lots, by a huge degree. Yes, me and my family going vegan doesn't have a huge impact, but it certainly massively reduces our carbon output, at a time when it just seems to be going up on a person to person basis. Last I checked, the amount that I was personally outputting was around 50% the US average. The only major difference was that I was vegan.
3. To maintain 7B people, most people will have to not eat meat, or eat it so sparingly as to be effectively vegan/vegetarian.
> A vegan diet is probably the single biggest way to reduce your impact on planet Earth, not just greenhouse gases, but global acidification, eutrophication, land use and water use.
> It is far bigger than cutting down on your flights or buying an electric car.
I don't care if you eat meat, but do it with honest realizations as to the cost. In a couple generations the costs will be clear, and our actions today regarding animal food production will be viewed for the atrocity that it is.
It's unfortunate that more people don't internalize this fact. One of the first things you learn in middle/high school ecology is that 90% of available energy is lost between each step in the food chain. Producers can only convert about 10% of the sun's energy to useful electrons in photosynthesis, herbivores only get 10% of the energy it takes to grow their food, and carnivores only get 10% of the energy herbivores take in. Some factors like the decreased non-predatory death improve those numbers for industrial agriculture but not by much.
In US agriculture, we have some estimates for the ratio of output calories to the input calories [1] that are astounding. For every 100 kcal of feed stock, we get ~19 kcal back from chicken, ~7 kcal from beef, and a whopping 1 kcal from shrimp.
Essentially, every 1000 kcal of beef takes 14,000 kcal of corn/soy/alfa-alfa and 1000 kcal of shrimp takes 100,000 kcal of whatever it is shrimp eat.

> avoiding one-time non-consumable items (one-time plates, forks, cups, cup-lids, straws, etc. are an absolute no-go—which means boycutting starbucks and similar if necessary)
Starbucks gets a lot of flack, from a lot of directions, but it's worth noting that companies go that could contribute a lot to this problem, they do a lot to promote better usage patterns. For example, you can bring your own cup to get filled at Starbucks, instead of using one of their cups (which uses recycled content).[1]
> And even more importantly, getting others to do the same.
And that's the reason I'm commenting. Really, I could care less whether people go to Starbucks. I'm there once a month or two (but I do gets treats for the kids there about once a week). But if we are supposed to be willing to change our behavior to make a difference, we should definitely be willing to look into whether a company is trying to do something good for the environment before denigrating them as a problem with regard to the environment.
If a company is taking steps in the right direction, we should call that out as a positive example, to encourage them to do more and others to follow in their example. Ignoring their positive actions, or worse, using them as a negative example, will not encourage positive behavior on their part.
> Starbucks gets a lot of flack, from a lot of directions, but it's worth noting that companies go that could contribute a lot to this problem, they do a lot to promote better usage patterns.
In that case, I do apologize. I have never in my life gone to a Starbucks, but my point was avoiding one-time use devices of any kind, regardless of what convenience it may bring, with the exception of when it is truly necessary (such as medical packaging).
However, do note that this also includes whatever one-time devices the company themselves use to run their service.
It would be a quite standard PR stunt to present visible environmentally friendly options (that potentially largely go unused), while not doing anything at all to the less visible parts of the company.
> It would be a quite standard PR stunt to present visible environmentally friendly options (that potentially largely go unused), while not doing anything at all to the less visible parts of the company.
Sure, but it's good to start somewhere. If we get companies competing on a level of environmental friendliness, then it quickly goes beyond being superficial, as those gains are quickly achieved and further ones are sought.
To some degree I think that's part of what's going on with Starbucks. They've positioned themselves as an environmentally aware company, and one that cares about world issues (carrying specific types of beans, etc). Part of this is obviously playing to their audience (and part is it starting in a locale and with a CEO that cater to these attitudes), but that's about all we can expect from most companies. Thankfully, it's something that can be worked with. If consumers express interest, companies will respond.
There's no reason for you to apologize, I just wanted to point out that we should be careful to not draw that line at those companies who are "good" or "great". We're at the level were we should be very welcoming of those that are only acceptable in their behavior with regard to this, but that's still worlds ahead of most, and that's how we move the average.
Spreading behaviour is so important. Which means it's important to make it "cool" to be environmentally conscious. I think people sometimes underestimate the cool factor when it comes to spreading ideas.
You can do all the cool but it is going to have no result when industry is responsible for a third of GHG, agriculture about a fourth and transportation a fifth.
To stop those takes regulations and laws. Major investments too which won't happen if not forced either.
Best targeted results for efficacy of behaviour modification at a fifth. Good luck. This with self-efficacy training. You cannot do that with everyone so you're bound to fail. Worse if people cannot adapt at all. Tell a guy they now go 50 miles to work by bike is not going to work at all.
You cannot destroy a mountain by removing a few shovels of ground. The action and change has to be both forced and massive.
Since 71% of pollution is coming from 100 companies[1] I don't think that you can stop global warming by being vegan or driving less. Blaming us single individuals is easy, but we a are not directly responsible for this. The most we can do is stop buying stuff from these polluting companies.
I see lots of companies that sell oil there. Or coal. Or things. But none that really emit pollution as a side effect.
Someone like 3M could pollute less by changing the way it produces each packet of yellow stickers. The pollution is a side effect, it's something the company can change by internal decisions.
Someone like Shell cannot pollute less by selling 1l of petroleum (I assume that pollution during production is a rounding error in this context). The pollution is inherent in the product sold. The act of polluting is identical with the act of selling.
Which implies that your last sentence should be "the most we can do is stop buying polluting products".
> Blaming us single individuals is easy, but we a are not directly responsible for this
Companies are comprised of people. Governments are comprised of people. We absolutely are responsible and we have the power to do something about it. Stop being so passive and dismissive, if you care.
>> Blaming us single individuals is easy, but we a are not directly responsible for this
> Companies are comprised of people. Governments are comprised of people. We absolutely are responsible and we have the power to do something about it. Stop being so passive and dismissive, if you care.
So what do you suggest? Blow those 100 companies up with TNT?
People with power have more, much more say than a typical person. Unfortunately, many of them are sociopaths or just do not care if there is no direct gain for them.
I'm saying a passive approach may give you a moral high but it doesn't actually do anything. Saying "Only someone else can fix this problem." is part of the problem, not the solution.
As someone who's been through several cycles of climate related depression this year, I just want to reach out to fellow HNers and say it's not the end of the world.
Our society, and our civilisation is going to change, in massive ways in the coming century, one way or another. And all of us are going to live in less luxury than we do now - simply because such luxury is unsustainable. But it doesn't mean or children are all going to starve or drown.
We don't know what the future holds. Go back to the boundless optimism of the fifties, where everyone thought we'd live on the moon by now, drive spaceships to work and have robot butlers. I feel like today some of us are at the other end of the spectrum, in boundless pesimism.
Do all you can to pollute less, and encourage those around you to do the same. Drive less. Don't fly. Buy second hand. Replace your oil boiler. Grow veg. Write to your representatives But don't give up on your children's future. Just because the world of their twenties won't resemble yours, doesn't mean they won't find happiness. In 30 years the world could be ugly by todays standards but you and i and our kids will probably all still be in it.
And for your own mental health, don't let HN comments drag you down. I've seen people on here literally advocating suicide over this issue. We as tech heads are typically of a personality which is susceptible to these negative feedback loops, and reading posts on here can break a person. I'm breaking my own rule today even being here but I'm feeling good for once and wanted to spread it.
Be well, have fun with your daughters, watch them grow up.
> How do you know at least some of our children are not going to starve, or worse, be forced into warfare over crucial resources?
Of course I can't know that, I have no crystal ball. I'm saying that assuming that we're all doomed is as bad as assuming everything is fine and denying the problem.
> 50s optimism and status quo dropped us into most of the current problems.
I wasn't advocating 50s optimism but rather saying it's an extreme and we've swung to the other extreme, at least on HN. I'm not optimistic about the future but I'm not fatally pessimistic about it either, at least not anymore. Reading comments here is a good way to trigger that fatal pessimism, make you want to quit your job, buy a gun and go live up a mountain.
> It is all fixable but the upheaval is likely going to be massive. We have no idea which form.
Exactly my point. There will be upheaval. We have no idea. And it won't be a magical fun time. But it might not be a hellish nightmare apocalypse either. Just bear that in mind, comment readers. Don't fall into despair about the future.
Don't be optimistic that we'll overcome resource depletion without suffering, be optimistic that our efforts can reduce that suffering. There isn't time to dodge the blow, but we can lessen the severity, and everyone who is capable and willing to support that goal is needed. Seek solutions, teach, enable others to do the same.
I read the book 'World War Z', and at the risk of ruining the book for someone, there was a statement near the end that really stuck with me. Some guy was reflecting on how they'd won, and he said 'Tell that to the whales', paraphrasing.
I cannot deal with the guilt of the loss of megafauna. I just can't. If justice only includes humanity, then it isn't justice. I feel as if I've reached this place using sound ethical logic, and I'm culpable for what we are doing to this planet. We are bacteria in a petri dish.
> I'm culpable for what we are doing to this planet
You didn't ask to be born, and you're doing your best to avoid harming the planet. You can't hold yourself responsible for the extinction of another species. Humans are of course responsible. Without us, earth would be a verdant paradise full of wild animals eating each other. But to blame yourself for centuries of humans consuming, burning, polluting, building, paving and getting rich off the misery of others is morally flawed. You're no more responsible for that than the child of a murderer is for his father's crime. And by being vegan, driving less, espousing green values to those around you (as I'm sure you do) you're having a net positive effect, even while you consume the resources you need to survive. Earth might be better off without humans around, but humans are better off with you around.
I think we can do it... you can email me at my username at gmail if you want to chat but we can talk it out a bit here too.
Is there any aspect to culture that you’re personally drawn to? Food? Walkable communities? Forests? Wildlife? Durable goods?
I really respect that you grasp the magnitude of the problem and you empathize with those who will live with the consequences. That says a lot of you. But you can't stay in a framework where you are feeling depressed about it. That's probably not a good framework to work from.
Yep. This is something people get wrong about the old Limits to Growth study: they assume it's just about running out of resources. Actually a key feature of the model is that you spend more and more resources on dealing with the effects of environmental damage.
The interesting result was that, given that dynamic, your economy keeps growing and everything looks great, then suddenly it all crashes down.
>>Hard to develop a space program when you're spending all your production fighting over scarce resources, plugging leaks, and attempting to feed a planet with decreasing yields.
All the more reason to develop your space program.
At the risk of pointing to Movies, but yet, one of the underlying themes in the movie Interstellar is some day there will be no option but to leave.
So its about time we think seriously about mining asteroids, space colonies and having some kind of permanent self sustaining and growing colonies in space.
Sure Humans are still likely to have the same problems, but you have eliminated the biggest threat to our existence, and we now have thousands of years at our disposal to plan the next steps.
It would take a whole lot for Earth to become less habital and more expensive than anywhere in space we can reach. Interstellar also included Matthew McConuhagh communicating quantum gravity info to his daughter in the past from inside a black hole. That’s not a realistic scenario.
Agreed. I loved "Interstellar", but leaving Earth is a hopeless prospect.
How do you move 8 billion people to another planet when it costs a $billion to send just 5 people into Earth orbit? Worse, there's nowhere enough sunlight and water anywhere in this solar system to sustain more than a handful of people.
No, if mankind can't make it here, we can't make it anywhere.
We can definitely colonize space. And we can make space travel vastly cheaper.
But I'm extremely doubtful we would ever reach a point where moving everyone off of earth is easier than fixing whatever is broken with earth. Or that it would even get within a factor of 10.
Moving everyone off-planet, no. Getting a presence up there, and creating off-planet production sites on the other hand, would be quite handy on the other hand. That way we could reduce the impact industrial production has on the planet.
See, exploring Earth takes almost no energy, mostly time and will and supplies. Ships at super efficient.
On the other hand, getting to 1st cosmic speed takes a lot of energy released in a relatively short burst or some kind of space elevator which we cannot build yet.
You cannot make this "gradual" really. You either get to orbit or don't. The "gradual" phase of getting into space is done. We got to orbit.
We need a major economy and scale breakthrough now or you cannot even try sending people off anywhere.
So major that small improvements as done by SpaceX will not get there in centuries.
Totally agree. I have a couple visions of attainable infrastructure evolutions, we should have every city and county helping sponsor X Prizes that would help us attain incredible improvements:
• elevate all city infrastructure up off the ground, 100 feet or more. If you figure that out you get arable, natural landscapes back and you keep your city too.
• How to bring light down to the ground underneath it all? I say we build transparent canals, use their shape to lense light through and around.
• these canals, there could be extra channels/tubes added to store and process dirty, utility and drinkable water
• create food programs that bring growing, harvesting, finishing and cooking down into the crowds of us who’d want to participate. Can we reduce the cost of food by orders of magnitude?
My grandfather, who raised me, was born in 1919 and died in 2003. He didn't say much about anything, but he watched, listened and observed, always.
He lived most of his adult life in suburban Southern California, but thanks to a 30 union job, and an early retirement, we spent each summer, all of it, camping in the eastern high sierras. Growing up with them, I first went in 1970, and (with them) last went in 1990.
He noted on more than one occasion how much less wildlife there was in the deep woods we used to hike together. He said it was 'quiet', and I sensed anxiety from the old man as he said it.
This moved the young me, profoundly, because my grandfather was the most stolid person I've ever known. No surprise: he spent his teenage years in the dust bowl, following a 5 mile trap line in the often brutal Nebraska winters, with a rifle, by the age of 14, in order to help keep the family from starvation. As a young man, he survived some of the most brutal battle in the Pacific.
A man who, faced with armed and dangerous gangs in the neighborhood he bought into decades earlier, showed no fear.
A man connected to the land in ways most of us can't even imagine today, he was worried about how the land was changing.
Thus, I effectively automatically, by default, became a young person who cared very deeply about the environment.

I consider all of this, and my 16 year old son, and no clarity is apparent to me.
Smoother airflow around the windshield means fewer bugs smashing into it and more glancing hits that don't leave a mess.
Traditional hard edged cars like Jeep Wrangler seem to get a lot of bugs on the windshield (based on brief Googling), so while there may be fewer insects I'd wager to guess aerodynamics is large factor.
Can confirm aerodynamics are part of it. I drive a 2013 Jeep Wrangler. Wife has a brand new, aerodynamic vehicle. Jeep definitely collects bugs, bird poop, and even rocks at a MUCH higher rate.
> Smoother airflow around the windshield means fewer bugs smashing into it and more glancing hits that don't leave a mess.
Not necessarily, I've noticed the same thing as the OP driving the same car, a small hatchback I bought 4 and a half years ago. One or two years after I had bought it I could still see lots of dead bugs on my windshield whenever I was driving to my parents, who live in the countryside, but during the last year or so the windshield has started to be more and more clean after each such trip. The same thing has been independently confirmed/noticed by my dad, as he likes to wash my car whenever I get to them, he told me that there used to be more dead bugs on the car.
What's scary for me is the speed with which things have changed for the worse as I remember a comment I made on this website about 2 years ago saying that I could still see lots of dead insects on my car after a highway trip, in response to a couple of HN-ers who lived in Western Europe saying they didn't (I live in Eastern Europe).
If you think aero styling is the reason your windshield is cleaner, then take a look at the largely vertical surfaces of your headlights and grille. No dead bugs there either.
If I look at pictures of my Westie camper van back in the mid-90's, the amount of bug splatter across the front from a few hours' drive is huge. It practically looks like a different shade of tan at a distance.
Same route, same drive 20 years on, and the grille is virtually clean.
Anecdata, I know, but it absolutely is something I've noticed, and the aero didn't change.
I have similar memories from my childhood in the 80's. We lived in Savannah and would make the trek to North Georgia several times a year to visit my mom's family. I can remember the headlights illuminating a sea of bugs like a light snow and the bigger ones popping loudly on the windshield from time to time. Having a full reservoir of wiper fluid was crucial and my dad would let me scrub the windshield whenever we stopped for gas.
I drive down to the Georgia coast or down to the gulf through Lower Alabama a least a couple times every year and it's rare to have anything of real size burst on the windshield.
I've been in this same thread a few months back. Insect loss is definitely happening, but bear in mind your lack of splatter probably also has a lot to do with better aerodynamics of cars these days. Bugs blow over the windshield on modern cars, they don't tend to splat as often. I live in an area with swarms of insects and i never have to clean anything off these days.
EDIT: Out walking my kids while i write this and i just swallowed a bug :(
I've read lots of anecdotes like this over recent years, with an increasing knot in my stomach. I don't drive much these days, renting as per requirement, so my own experience in the matter is limited. That said, I had to drive to the south coast one Sunday this past summer and know for a fact that for one day a year at least, England needn't panic too much about catastrophic impending insect implosion. I know this because I discovered half-way through the journey that there was no liquid in the window washers, so by the time we reached our destination, the windscreen was caked in obliterated insect matter and we had to spend a good 15 minutes with a bottle of inappropriately-carbonated water trying to clean it off for the return journey!
My hope is that a reduction here is indeed more to do with improved vehicle aerodynamics.
Certainly, my sense of dread through springtime, seeing very few insects dissipated quite quickly after a few evenings being irritated by a multitude of flying critters.
A welcome irritation though, one which I hope to always be able to appreciate...
I went camping in west Texas last summer and any lights we had on attracted enormous swarms of flying critters. I do not say that to discount you or OP but rather to console with the fact that there are still times and places where this occurs.
I find I tend to see a lot of bugs during hatches. You only see one kind, it lasts a few days, and then it's back to normal. Maybe that's what you saw.
I wonder if part of the effect can be explained by the improved aerodynamics of cars. I used to drive a 1966 FJ40 Landcruiser about 10 years ago and remember having to clean bugs off the car. I don't have as much to compare it to as you since I've only been driving since 1996, but I didn't notice any major difference in that time period.
Just another data point to add: exactly the same thing has happened here in Australia. The family used to regularly drive 2000km on holidays. Dead bugs covered the windshield and radiator at the end of each leg.
Today with cheap plane fares we don't drive so much, but I still do a one 1000km drive every 5 years or so. I don't recall washing a single bug off whereas when I was a kid scraping dried bug guts was a major chore.
76% sounds almost too low, but I suspect the the biggest bugs are the hardest hit and they caused the mess on the car. I don't remember when I last saw a locust. They used to be a major problem. We used to have surfaces carpeted in beetles during their breeding season, and yet this Christmas I was actually surprised when I saw a Christmas beetle.
That the environment could slowly transition its chemistry into a state which is not suitable for life is one of my biggest fears. It would be a silent killer.
Life is pretty resilient. I'm sure some bacteria would manage to survive pretty much anything. Life survived a number of extinction events where >90% of all species were lost, so the chances are good that life will go on.
Life will definitely go on, but this would seem to be our sole chance at getting off the planet. Any future reboot wouldn't have the cheap energy resources we've exploited to this point.
I should have said "human life". A world that is no longer suitable for mammals but is suitable for microbes falls under the category of "things that scare me".
The dinosaurs evolved in a climate with 6 times the CO2 we have, after long term volcanic activity. It will take a lot more than climate change to knock out all life. Maybe a gamma ray burster a few light years a way could do it, or a massive collision that melts the crust. Not much else, though. Life as a whole is extremely reilient.
Not sure why that would be. Our ancestors survived an ice age while outcompeting Neanderthals with primitive stone aged technology, and spread from Africa all the way to Easter Island, the depths of the Amazon and Tasmania.
I am not convinced that life on the planet will survive. We could very well turn into Venus. Maybe we did already. In previous cataclysmic events, life was spread en masse to low earth orbit, to return after the fires died down and the earth cooled off. We have no such seed bank in orbit now.
"Life" means humans in this context. If the environment changes so much that it leaves microbes around but not mammals, that's what is scary. We're mammals. We're not as resilient as microbes are.
I live in a ruralish area in Brazil... And while talking to someone on webcam I noticed a couple hugs wandering around the person room and the person in question not caring at all...
Then we I was wondering about it, I realized that been some years that my house despite being near some woods and rivers, is not plagued anymore by insects. I think last time we bothered with anti mosquito candles was 3 years ago...
I recently went camping in mountains that I hadn't camped in for 15-20 years or so, and I remember constantly dealing with yellowjackets and bees all sorts of other fauna. I think I saw one yellowjacket the entire trip, and we had food out like crazy.
Plus, whereas I was used to waking up to the sounds of birds and animals, our campsite was completely silent. There was one hawk in the distance all morning.

Whatever it is, it's not happening to mosquitoes. This entire summer I had at least 5 of them buzzing around my head every night- and I did swat at least half of them each evening.
Annual mosquito infestations have been irregular of late. This year was the worst in maybe the past five, probably due to the insane amount of rain we've had in the Philly area.
But in the past several years I remember being surprised that mosquitoes really didn't pose much of a problem. I could work in the yard well past sunset without becoming vampire food. That wasn't true a decade ago, IIRC.
Parent's comment is "Actually X can't be happening because Y happened to me". GP's comment is "Z is happening, which might explain why I've noticed W". Parent's comment is textbook cherry-picking, GP's is closer to a regular anecdote.
I certainly agree that my anecdote doesn't prove anything, but I'm not sure it's imperative to immediately attack it as faulty reasoning. For one thing, I meant it in a more whimsical manner than perhaps comes across in my comment. As in a "bloody mosquitoes" kind of way.
In any case, some background might be useful: this happened in Corfu, an island in the Ionian Sea (to the west of Greece). Corfu, like the rest of Greece, used to have a big problem with mosquitoes spreading malaria, so in the 1950s the whole island was sprayed repeatedly from the air with DDT, to eliminate them. I believe the same was done in other parts of Greece.
Possibly as a result of that, the incidence of malaria in Greece is either 0 or negligible, nowadays. Which, despite the ecological catastrophy wrought by spraying bloody DDT on the entire countryside, is a big success- Greeks are among the Mediterrannean populations with a high prevalence of Thalassemia, a genetic modification that helps resist malaria (and which can lead to a sickle-cell anemia, a serious blood disorder):
Which means that there was a really significant problem there in the past.
So, when I say that there are many mosquitoes, I mean that I'm surprised there's still so many of the little blighters in Corfu, even given the protracted past campaign to eliminate them- and also given whatever else is happening in the rest of the world that's affecting insects, even though there's no reason that thing is also affecting Corfu, in particular.
But, OK, that doesn't come across in my original comment :)
GP's comment says "has been happening" and parent's says "is not happening." I don't see any "might." Both are anecdotal; GP's is likely more upvoted due to being more poetic as well as supported by the accompanying article.
The windshield ended so pestered with dead bugs that the first task on Saturday morning was to drive the car to the river to clean it. I remember it vividly because it was so fun to wash the car with the cold river water.
Last August I went stargazing with my wife. We chose a secluded area because it was far away from light pollution, a few hours away from the capital.
We watched the Perseids for a couple of hours in the middle of a field. We had no lights on, but being CO2-emitting mammals, no flying insect bothered us. We had anti-mosquito spray ready but we didn't need to use it. There were a few ants but that's it.
Afterwards, I drove an hour and a half at 2am and only a few bugs died on my windshield. I didn't even need to use the wipers the next morning.
I hate mosquitoes as much as everybody else, but something has been happening to insects in the last 20 years. As a human it's comfortable but I'm honestly a bit afraid for the environment. And studies like this don't paint a positive picture.
