What would it be like to live in a world with clean air

We take such things for granted, clean air and water, always thought these two things were god given, NOT. A day in ER will bring you back to reality.  This is an issue that should not be taken lightly, as I now know what it is like to not be able to breath. All the millions of people with asthma, who suffer daily, some of this could actually be avoided if we had clean air to breath.  Unknown to many are the effects of heavy metals to health. Breathing is on the top of the list. There are many informational web sites this is just one of them http://www.ei-resource.org/illness-information/related-conditions/heavy-metal-toxicity/.  You would think living in rural North Dakota, we would all enjoy healthy living, after all we don't have smog and pollution like the cities, instead we have something better, oilfield toxins to hide our clean air. How many burning flares are there in Williams Co alone? I would be curious to know. Now I would imagine some would not agree with this, as of course all the companies abide by regulations and this is monitored by the EPA. I wonder if there is any place left that is safe to live?
