Just Thoughts on Air

Usually I keep trying to write something "scientifically substantiated", but for today only this:

The two things our bodies need the most urgently to survive are air and water.
We can live like a few minutes without air and like 3 days without water.

In today's world big companies and even governments are playing with our health by not
caring in the case of big business and by not controlling the quality of these resources
in the case of governments.
It's not that long ago that you could still drink water out of a river, what an outrageous
concept nowadays.
And the air ? Let's not get started between cars and industrial chimneys the
atmosphere is like a big toilet of pollutants.
In case you don't believe that keep on dreaming, ignorance is a bliss.

In the light of these thoughts I'd go into a hyperbaric chamber just to have the luxury of
breathing clean air for a couple of hours.

Here is something from a Canadian Government webpage:

"The human health effects of poor air quality are far reaching, but principally affect the body's respiratory system and the cardiovascular system.  Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, the individual's health status and genetics.  People who exercise outdoors, for example, on hot, smoggy days increase their exposure to pollutants in the air.
The health effects caused by air pollutants may range from subtle biochemical and physiological changes to difficulty breathing, wheezing, coughing and aggravation of existing respiratory and cardiac conditions.  These effects can result in increased medication use, increased doctor or emergency room visits, more hospital admissions and even premature death."
