Production predictions

Buried in the latest mineral commodity reports from USGS are predictions on production for 2007. It is estimated that in 2007, domestic production and apparent consumption of crushed stone will be about 1.73 billion tons, a 2 percent increase. It is also estimated that 2007 domestic production of sand and gravel will increase to 1.29 billion tons and U.S. apparent consumption will increase to about 1.3 billion tons. So, do the math. If USGS's predictions pan out, 2007 will finally be the year that we reach the mythical 3 billion ton-per-year mark. Your comment?
