Yes, I know that in big cities (like Los Angeles and New York) do have smog. I also wouldn't want to live in a big city because of that and the noise levels, space problems, etc.
I've heard that the American government owes money to China. I think most of us are just holding our breath now until the next presidential election, which hopefully will bring much-needed changes.
With the air polution problem, this article on smog related deaths may be of interest to you guys (although it focuses on england, i think it is relevant to places like america too);
"Summer smog causes the deaths of more than 3,000 people each year, the Liberal Democrats have warned."
"The photochemical reactions involving these "precursors", as they are known, will create harmful ozone which can affect people's airways.
Even normally fit and health people may experience a shortness of breath, some coughing, chest tightness, or just irritation of the nose and throat.
Summer smog can also contain high levels of breathable dust, often referred to as particulate matter";

"People are being warned of the possible health risks after officials issued a smog warning for many parts of England."
"It said people sensitive to air pollution, such as those with heart and lung conditions, should heed the alert.
Ben Bradshaw, minister for local environmental quality, said people should "take sensible precautions, such as avoiding exertion outdoors on hot afternoons" to protect their health"
"People who are particularly sensitive to air pollution may begin to notice an effect on their breathing in the coming days.
Asthma sufferers are not necessarily more sensitive but, if affected, are advised to use their inhaler."
"During the 2003 heatwave, it was estimated... that up to 800 premature deaths may have occurred as a result of the poor air quality.";

" Officials believe that as many as 12,000 people may have died in the great London smog of 1952.
Many of those killed were elderly people or those who were already weak or ill.
According to medical staff who treated patients at the time, few people realised the extent of the impact"
"The interesting thing is that no one realised at the time that the no of deaths were increasing," he told the BBC.
"There weren't bodies lying around in the street and no one really noticed that more people were dying."
""We are better off but not as much better off as we might have thought. Fifty years on the great smogs are gone but invisible pollutants are still taking a major toll on health.
"Some 20,000 in England alone suffer shortened lives each year."
He says vehicle emissions are the main culprits and believes the government should be doing more to tackle the problem";

Pretty worrying stuff, huh? I'm glad i don't live in London at the very least

.
But there is no doubt that all this air polution is destroying the health of our people, even if not everyone believe's in global warming, we should still try to cut down on levels of air polution for the health of our people at the very least.
People have a choice whether to smoke tobacco or not, if they die from it then thats just the risk they bargained to take when they took up smoking, but people who die from air polution have no choice whatsoever in the matter, everyone knows now days tobacco can give you lung cancer, but i wonder how many people realise the health problems of smog?
I don't really have anything against those that smoke, i am a light smoker myself, i know the risks of my habit to my health, but i think it is very unfair that people can die simply for living in their home city and many of these people are probably completely oblivious to the health impacts their choice of area to live in is having on their health. How many people's grandparents have died before their time because of smog, how many people's premature babies have died when they wouldn't of because of smog, how many people with illnesses have died because of smog when they could have otherwise lived and lead fullfilling happy lives etc?
IMHO, the government needs to do far more on making people aware how bad air polution in cities is for our health, so at least people can make a more informed choice on whether they want to live in a city with smog or not etc. From what i have seen, smog in london is not as bad as the smog in places like LA, i wonder how high the death and illness toll is for those living in LA due to the smog levels there? It is probably a lot higher toll.
More articles on air polution, this one is on children living in the US;
"Atmospheric pollution discriminates between the sexes, a study has found.
It examined the effects of smog on the respiratory systems of boys and girls, and found that while polluting gases affected boys most, particle pollution affected girls.
Scientists have no explanation as to why this might be."
"The finding is the latest surprise to emerge from a comprehensive look at the health effects of air pollution on US children."
"Children are particularly vulnerable to the effect of pollution"
"The study also showed both sexes suffered from pollution-related ill health.
Children in the most polluted communities covered by the research had lung growth about 5% lower than normal.
Coughing and wheezing among asthmatics was found to be more severe in areas with higher levels of nitrogen oxide and particle pollution";
