Erosion In China Creates Dust Storms Over U.S.

"Earlier this year, an unusually large dust cloud that originated in northwest China drifted across the continental United States and lingered over Denver and other areas, at times obscuring views of the Rocky Mountains.It isn't the first time a giant dust cloud from east Asia has reached the United States. But concerned observers say the vast sweep and the density of this latest one suggests that northwest China's once-fruitful agricultural land is eroding at an alarming rate, becoming useless desert."
