Something I have never read about, is every infernal combustion engine needs air to complete the combustion, and, how much in needed for each cycle of the engines.

Oxygen levels are decreasing in the atmosphere, and there is never any words written about how this is happening. Just think about all these hoovers on the roads everyday, sucking in all the air and releasing carbon dioxide and carbon monoxide pollutants without oxygen.
