It's not bad enough that soon we'll run out of bluefin tuna, now scientists are saying that we may also lose wheat. The stem rust fungus could wipe out 80% of the world's wheat as it spread from Africa.
Enjoy your bread while it lasts! Karen Kaplan of the Los Angeles Times has the story of a "time bomb" for wheat:
Crop scientists fear the Ug99 fungus could wipe out more than 80% of worldwide wheat crops as it spreads from eastern Africa. It has already jumped the Red Sea and traveled as far as Iran. Experts say it is poised to enter the breadbasket of northern India and Pakistan, and the wind will inevitably carry it to Russia, China and even North America -- if it doesn't hitch a ride with people first.
"It's a time bomb," said Jim Peterson, a professor of wheat breeding and genetics at Oregon State University in Corvallis. "It moves in the air, it can move in clothing on an airplane. We know it's going to be here. It's a matter of how long it's going to take."
Though most Americans have never heard of it, Ug99 -- a type of fungus called stem rust because it produces reddish-brown flakes on plant stalks -- is the No. 1 threat to the world's most widely grown crop.
