The Iowa Farm Bureau says the current cap and trade bill moving through Congress could have a devastating impact on Agriculture. IFB national policy advisor Marty Schwager says higher energy prices, would lead to increased production costs. Schwager says the Farm Bureau estimates that if the cap and trade bill passes, U-S farmers will see production costs go up by five-billion dollars by the year 2020. He says they would favor a voluntary, market based way to reduce greenhouse gases.
