"The prickly pear cactus may not sound like a trendy cash crop, but it could become a phenomenon among farmers on the arid west side of the San Joaquin Valley."

"With the specter of past deadly poisonings, the food industry steps up its quest for clean salad greens, testing various industrial washes and other methods like ultrasound."

"Hoping to combat the growing problem of childhood obesity, the Obama administration on Wednesday announced its long-awaited changes to government-subsidized school meals, a final round of rules that adds more fruits and green vegetables to breakfasts and lunches and reduces the amount of salt and fat."

Detroit, one of the birthplaces of American industrial capitalism, has also been in many ways one of its earlier deathplaces -- an urban landscape where many houses and lots are abandoned.
