Why control human caused sources of dust when there is so much naturally occurring windblown dust?

Human activities tend to occur in more populated areas, and any dust they create can be more likely to affect public health. Nobody is planning to pave the desert, but we do need to address how human-created sources may contribute to overall levels of dust in the air.
