Bacteria and dust are everywhere, surviving in even the most extreme environments like hot springs, ice cubes, and the air we breathe. But not all of them are malicious, just be aware they are present
Bacteria may travel thousands of miles through the air worldwide instead of hitching rides with people and animals. Researchers at Rutgers University and other colleagues suggest that there must be a planet-wide mechanism that ensures the exchange of bacteria between faraway places. 1
Air samples collected by scientists at Lawrence Berkeley National laboratory found as many as 1,800
bacterial species in the air we breathe. These bacterial life forms are not just on us and around us, they are part of us. Yale University engineers for instance, have found that a person's 'mere presence' in a room adds about thirty-seven million bacteria to the mix, every single hour. 2
