The earth is 4.543 billion years old. Our ancestors have been estimated to date back to six million years, with modern human life dating to 200,000 years ago (Reed). The effects of humanity on earth can be exhibited by the increase of pollution within our world. As our population begins to grow, so does our carbon footprint upon the earth. On a more localized scale, the Central Valley is a mecca to poor air quality and elevating pollution levels. An assortment of environmental factors increases pollution levels. The central Valley is a mecca for the climate, natural, industrial, mobile and agricultural components that equate to this growing problem.
Pollution, otherwise known as PM, or particulate matter, is essentially any substance that is not made up of water. PM is most commonly made of dust, ash, smoke, fumes, vapors and mists, emitted from a source and absorbed into the ozone. Particulate matter that is emitted directly from a source, is called primary PM. Particulate matter that is formed in the atmosphere by gas is called secondary PM. There are two certified health based standards classifying particulate matter: PM10, for particles smaller than 10 microns, and PM2.5, for particles smaller than 2.5. PM10 is made up of course dust particles. Common PM10 sources include: crushing or grinding operations, as well as soil stirred up in our valley’s vast fields, or dirt roads. PM2.5 is composed of finer particles. Elements most commonly produced by combustion, motor
