Farmers from around the state will have the opportunity to discuss labor issues, environmental debates and agricultural policy at their annual convention.

The Utah Farm Bureau will host its 91st annual convention today through Friday at the Salt Palace Convention Center.

The keynote speaker will be retired Navy Cmdr. Scott Waddle, who was at the helm of the nuclear submarine USS Greenville when it collided with a Japanese fishing boat in 2001. He took full responsibility for the accident and apologized to the families, and he is now using that experience to discuss integrity and faith.

Global warming will be debated by Dianne Nielsen, energy adviser for Gov. Jon Huntsman Jr., and Chris Horner, author of "The Politically Incorrect Guide to Climate Change." There will also be speeches by American Farm Bureau President Bob Stallman and Utah Senate President John Valentine, R-Orem.

Between speeches, farmers can attend breakout sessions that focus on issues such as the carbon tax credits, cheatgrass growth and the valuation of water. For information, visit www.utfb.fb.org or call 801-233-3040.
