"Airborne dust contains respirable particulate matter (PM10), which consists of particles or droplets less than 10 microns in diameter. PM10  emissions are caused by road dust, diesel soot, combustion products, tire and brake abrasion, construction operations, and fires. The level of PM10 in the air is a public health concern because it can bypass the body's natural filtration system more easily than larger particles, and can lodge deep in the lungs causing respiratory problems and permanent lung damage. It also scatters 
light and significantly reduces visibility. Fine particulate matter (PM2.5) is defined as extremely small suspended particles or droplets with a diameter of less than 2.5 microns. PM2.5 consists mostly of combustion byproducts from the reaction of exhaust sulfates and nitrates, along with finer dust particles. It is more closely linked to adverse health effects, and contributes to hospital and emergency room visits and is associated with asthma, bronchitis, cardiac arrhythmia, heart attack, and premature death." (SMAQMD, "Model General Plan Air Quality Element")

In California, over tilling of farmland produces over 130 tons of PM10 and over 20 tons of PM2.5 A DAY (annual average). This is in ADDITION to over 160 tons/day of PM10 and over 25 tons/day of PM2.5 that just blows off the surfaces of these finely pulverized fields (called "Fugitive Dust" by CARB). (Numbers are from CARB's 2009 Air Quality Data Almanac.)

Yet, it's not a major political topic. Why? Good question, ask your congressman and Obama (oh wait he's on vacation.)
