Taiwan actually cleaned up its pollution problems over the past decade. They are a world leader in recycling, and generate much less air pollution now that most factories have moved to China

Includes "natural sources" - that must be the sandstorms in the desert, so many of these countries are in and around Sahara.

Yeah, when I figured that out I just started typing in desert countries. Surprised no micronations are on this list, because in those cases the entire country is a city, and any modern city is way more poluted than the surrounding country side.

I flirted with the idea of Nepal being on the list but didn't type it. I thought a country in the middle of the Himalayas would have minimum pollution. Alas! Didn't read the natural sources part. I suppose the frequent blizzards might be why it's on the list.

True. And this data measures human exposure. Most of the population of Nepal lives at lower elevation where pollution is heavy.

Kathmandu is horrifically polluted. The biggest reason is unregulated car emissions, but it's exacerbated by general lack of development: they still use do things like use chimneyed cooking stoves and burn their trash. Yet there's still a huge population growth rate, and with money brought in by Everest climbers and the Tibetan religious refugees' followers/students (who are white, Western, and affluent),there are always development/construction projects going on, which stirs up tons of dust (Nepal isn't exactly lush). I don't know if Kathmandu itself is bad enough to drag the whole country's average down or if the whole country is just socked in by weather patterns, but either way, take an industrial-strength gas mask with you.

they go out and spray water on some of it around cities in Saudi Arabia, and also a tar-like substance in some places which is more effective.

The oil money all goes to their country's insanely disproportionate 1%, who buy giant mansions in places like Monaco, the US, and Switzerland, garages full of priceless cars, yachts, private planes, and hotels in Beverly Hills – then spend most of their time out of the country frolicking. They don't give a flying turd about improving infrastructure or the plight of the poor in their home country (even if they're the rulers too, which often is the case).

There's not really much they can do about the sandstorms in Saudi Arabia. They do a bit, as I described above, but the Arabian desert is pretty big. Also, though there are an estimated 30,000 princes in Saudi Arabia that's more like a tenth of one percent. And to be fair a lot of oil money HAS gone in to improving public infrastructure in these countries. You want to go and take a look at the roads and public transportation options in Dubai, and then compare those to what you might see in Egypt or Yemen? Pretty stark contrast. Though there is also a lot of corruption, but there's enough money to go around in many cases.

I've spent a lot of time in Saudi Arabia and the Philippines and I feel like the air quality in the Philippines is markedly worse. Maybe not if you factor in the entire country as a whole, as most of the pollution in the Philippines surrounds major cities while the sand in the air in Saudi you can find everywhere.

Burning wood for heat and cooking does not help. Fly over many of these countries at night and you see thousands and thousands of fires burning in the night.

I associate pollution with the negative by-product of industry down through more individual contributions like consumer waste. Natural phenomena like sand storms seem to be heavily skewing these numbers.

The inclusion of natural events makes this quiz pretty much useless in my opinion. Sandstorms and blizzards are not what people think about when they hear the word 'pollution'.

You need to specify that this is in terms of PM 2.5 levels, if indeed that is what it is
