They didn't mention whether the effect remained constant regardless of population density.

I'm a big proponent of "you probably shouldn't be inhaling more than you need to of any sort of particle" but I wouldn't be surprised if the small amounts of extra stress of day to day life in a more densely populated area isn't good for you.

Someday people may also look back at the television and the smartphone and compare the garbage we call mass media that we put into our minds to the lead in Roman water pipes.

If they did, I would hope people around them recognized that their conflation of neurotoxins in water and largely benign electronics makes very little sense. I think I understand the sentiment, but I don't think the three are the same. And if they had similar results, hypothetically, they would be for entirely different reasons. edit: I'm interested to know more about peoples' concerns about smartphones and other dev…

dopamine addiction coming from and through the benign electronics may count for something.

I wouldn't be surprised if some future historians are able to look back at modern cities the same way that we look at granny pictures of a soot-streaked city of the industrial revolution. "Yes, some of them thought that it was bad to have all that stuff around, but most thought it wasn't too serious compared to the immediate economic benefit it brought."

The Romans also used lead acetate as a sweetener.

They had to use what they could to make better things. It provided better economic benefit, and ultimately better life for us all (such as antibiotics).

choose not to use them, as in 'collectively until we are wiser and... '

Are you referring to non-ionizing radiation? Is there anything yet to show negative effects? My understanding is that there hadn't been conclusive study, but from what we know of thermal radiation there aren't known mechanisms for damage to occur within the FCC(think it's their rules?) guidelines.

They refer to "mass media", so I assume the point is technology as a dopamine button... however, cell phones have been linked to damaged / lower quality sperm in men. That could subtly damage society in the same way that lead-based paints hurt Rome.

Yes. A number of generations had a good life. But what about the coming generations. What does the "progress at any cost", have in store for them?

All things considered, what does the future look right now?

I definitely get a little worried about fumes, in a modern urban city. Diesel pollutants are local, and when I walk across a 4+ lane street with traffic, I always find myself practically gagging on exhaust fumes. That can't be healthy.

We should really ban big diesel rigs from areas with population density above a certain threshold. Especially considering how little the regulations around diesel emissions are actually complied with.

Extra psychological stress is always detrimental. They did mention other variables, including noise and other gasses, were not controlled for.

However, the mouse study removed those variables:

> He exposed mice to high levels of fine particulate air pollution five times a week, eight hours a day, to mimic the exposure a human commuter might receive if he or she lived in the suburbs and worked in a smoggy city (Molecular Psychiatry, 2011). After 10 months, they found that the mice that had been exposed to polluted air took longer to learn a maze task and made more mistakes than mice that had not breathed in the pollution. > > Nelson also found that the pollutant-exposed mice showed signs of the rodent equivalent of depression. Mice said to express depressive-like symptoms give up swimming more quickly in a forced swim test and stop sipping sugar water that they normally find attractive. Both behaviors can be reversed with antidepressants. Nelson found that mice exposed to the polluted air scored higher on tests of depressive-like responses.

I suggest reading the article. There were other disturbing changes that strongly suggest pollution may be the modern analogue to the Roman Empire's lead paint. It's definitely worth significant and rapid research investment.

Nonsense. This has nothing to do with the planet being destroyed, but minor health effects of air pollution. Which in first world countries, is vastly less than it used to be. And could be eliminated entirely in a few years with technology like solar power and electric cars. Possibly it could have been seriously cut back decades ago, if environmentalists hadn't fought so hard against nuclear.
