Chemical sunscreen famously kills coral.
Some dermatologists have noted that sunscreen is little used in Africa. [1]
I’m not saying that is the only explanation for the reef’s preservation, but it’s likely a significant contributing factor.

I couldn’t argue with you, but here’s their answer. The arguments appeal explicitly to people “who remember when”:
Need more convincing? How about a commercial operating system which doesn’t spy on you, does not report your online activity to anyone, and gives you complete freedom to choose the applications you want to use, however you want to use them? How about an operating system which isn’t tied to any specific hardware manufacturer, allowing you to choose the platform which is right for you, and fits perfectly well in systems with less than 4GB of memory or even virtual machines?
It's a fair and good question.

It's very well written and illustrated.
Big takeaways:
* Population-weighted findings. Air pollution is a bigger public health threat than (say) tobacco and alcohol not because it's worse for you individually (although it's terrible), but because the regions most affected are so densely populated
* Regulatory policy really works. "After periods of industrialization led to pollution that choked Europe and the United States decades ago, the two regions have largely been successfully creating and enforcing strong pollution laws. In the United States, legislative measures like the Clean Air Act have helped to reduce pollution by 64.9 percent since 1970, extending the average lifespan by 1.4 years" and similar improvements began in Europe 25 years ago, and even in China 10 years ago

Higher intensities of the same sounds had no effect on animals’ pain responses. “In mice, we found that sound-induced analgesia depended on its low SNR rather than harmony, which is supported by a previous hypothesis that music-induced analgesia is attributable to contextual factors of the treatment, not only to the music per se,” they wrote. “We were really surprised that the intensity of sound, and not the category or perceived pleasantness of sound would matter,” Liu said.
…
The authors further stated that the observed low-SNR sound–induced analgesia is “unlikely to result from some reduction in anxiety or stress, and it probably does not directly involve attention-distraction in affecting pain perception, given that the analgesic effects persisted for at least two days after sound withdrawal.”
This would be an appropriate riposte to [1], a vitriolic comment that draws the line between VC money and Electron, but not to parent.
Parent makes a lot of sense, actually, in context of the submission headline. There was no misinformation here at all.
Careful where this "sort of deserve" talk goes.

Folks with sensitivity to sound: consider supplementing chelated magnesium.
When I tried magnesium glycinate to help with sleep, I happily discovered my daytime sensitivity to loud sounds improved too. Turns out this is common: https://psychcentral.com/blog/living-with-extreme-sound-sens...
> In my practice, 85 percent of my patients came to me with a severe magnesium deficiency. A deficiency in this mineral often leads to anxiety, mood swings, personality disorders, sound sensitivity, light sensitivity, and insomnia. Magnesium has been shown to mitigate the neurotransmitter glutamate while easing the anxiety and anger experienced by someone with most types of sound sensitivity. Chelated magnesium is one of the best types of mineral supplements as it is very small and easy for the body to absorb and make use of.
