29 Jul 08 - A recent nationwide survey conducted by the United Soybean Board (USB) and soybean checkoff revealed that U.S. consumers strongly back U.S. soybean farmers and biodiesel.

The "National Agriculture Image Survey" indicated 82 percent of consumers agree foreign oil-producing countries and the high cost of fuel impacting farming and processing, packaging, storing and shipping food are to blame for food price increases, not U.S. farmers.
Other key findings show:

- 77 percent of consumers favor the use of biodiesel as a source of energy that can meet our needs in the next 5 to 10 years.

- 74 percent of consumers were more favorable toward biodiesel after hearing it benefits the environment.

- 70 percent of consumers were more favorable toward biodiesel after hearing it's a new green industry that creates jobs.
