resistance to lung infections and colds. Smog is especially harmful to young children, the elderly, and those with respiratory problems. The environment has also been tested by smog. Smog has been known to damage trees which are greatly needed to produce
oxygen and clean the present unhealthy air. Moss and lichen are also being destroyed in
many forests by smog.
The second deadly gas to be discussed would be carbon monoxide. Carbon monoxide is a colorless, odorless, poisonous gas. To learn more about this topic, see http://www.epa.gov/docs.iaq/pubs/senseles.html. Carbon monoxide is made of a carbon
atom and an oxygen atom linked together. When automobiles are not properly tuned or
properly turned on\off, carbon monoxide will seep out of an automobile’s tail pipe. This lethal gas is a product of incomplete burning of hydrocarbon-based fuels, which then seeps and spreads into the atmosphere and eventually ripping a hole in the ozone layer.
Carbon monoxide enters the blood stream through the lungs and forms a compound that eliminates blood carrying oxygen to the organs and tissues. People with heart disease are especially sensitive to carbon monoxide. Carbon monoxide can impair exercising, visual perception, learning functions, and the ability to perform complex tasks. The ozone layer, the earth’s only protection from the sun’s deadly ultra violet rays, is
