Which cities have the most and least air pollution?

The United States is the leader in terms of annual air pollution, with more than 200,000 premature deaths and an estimated $100 billion in economic damage each year.

But in some places, the picture is even bleaker.

In some places like Oklahoma City, the number of premature deaths is more than three times the national average, and the economic damage is twice the national total.

This is what air pollution looks like in Oklahoma City.

The city, with a population of more than 12,000, is one of Oklahoma’s poorest, and in the city, there are two major air pollution hotspots: the oil industry and the city’s central business district.

A key driver of air pollution in Oklahoma is the oil and gas industry.

The industry is responsible for producing about half of the state’s oil and is the biggest employer in the state.

It is a large and well-financed industry that produces oil, natural gas and other fossil fuels that contribute to climate change and pollution around the world.

Oklahoma City is the second-biggest oil producer in the US, after the Gulf of Mexico.

The oil industry is not exempt from air pollution either.

It emits particulate matter, and is responsible to clean up the air around its facilities, but there are some areas where the pollution is not a concern.

The Oklahoma City Municipal Air Quality Management District is one such area.

It regulates pollution in the central business area, a region around the downtown area.

It has been one of the top polluters in Oklahoma in recent years.

“Our goal is to improve the air quality in central Oklahoma,” said district administrator Julie Lutz.

“When you look at the number, it’s actually pretty good, but you’re not seeing a lot of the results,” Lutz said.

In 2015, Oklahoma City had the third-highest annual number of air quality violations of any Oklahoma city, after Tulsa and Tulsa International Airport.

Oklahomans live in Oklahoma’s oil industry, and it is a source of economic activity for the city.

Oil and gas companies use the area as a processing facility, but also as a hub for new oil and natural gas drilling, as well as for exporting.

The district has more than 25 air monitors that measure the amount of particulate pollution in and around central Oklahoma.

“The district monitors air quality and we are able to identify problems,” Lutz said.

“If we see a problem that’s not being seen in other areas, we’re able to put together an action plan to fix it.”

Oklahoma’s oil boom has seen the city expand and diversify.

It now has more restaurants and hotels than anywhere else in the world, and restaurants are opening all over town.

But Lutz says the district does not have the money to hire new staff.

The oil industry has also contributed to air pollution.

It produces more greenhouse gases than any other industry, so the air pollution is contributing to the warming climate.

Okieos oil industry contributes about 4% to the state total emissions.

“It’s pretty hard to quantify what it means,” Luts said.

The federal government is also watching Oklahoma closely.

In 2016, the Federal Aviation Administration said it was looking into whether the air in central OKC was a threat to public health.

The agency said it would issue an air quality advisory if the level was too high.

Okies are also a major source of pollution to other states, and they also face the risk of pollution from other sources.

In January 2017, the EPA released a list of air pollutants in Oklahoma that are not considered to be a threat by the agency.

The air quality was a concern in Oklahoma Springs, which has a population in the region of about 3,500 people.

Air pollution in some parts of Oklahoma City can cause headaches and other health issues.

But there are many places where air pollution has not been a problem.
