You walk into the grocery store, wanting to buy some Granny Smith apples for a pie you’re planning to bake. You find there are two types—organic apples from across the country, or apples from a local farm that uses chemical pesticides and herbicides. Which do you choose?

It’s a conundrum we’ve all faced at one time or another, particularly since 2007, when a University of Alberta study announced that the climate-change benefits of organic food are almost negated when that food has traveled a long distance from farm to plate.

WASHINGTON (AFP) – US First Lady Michelle Obama welcomes spouses of world leaders attending the UN General Assembly for a luncheon at a New York farm next week to highlight sustainable agriculture, the White House said Friday.

The wife of President Barack Obama will next Friday join the visiting spouses to tour Stone Barns Center, a non-profit farm and education center north of New York, officials said.

LUNCH LINE reframes the school lunch debate through an examination of the program's surprising past, uncertain present, and possible future.

In the film, six kids from one of the toughest neighborhoods in Chicago set out to fix school lunch and end up at the White House.

International scientists confirm dangers of Roundup at GMO-Free Regions Conference in Brussels Brussels 16 September 2010 Glyphosate, the active ingredient in the world’s best-selling weedkiller Roundup, causes malformations in frog and chicken embryos at doses far lower than those used in agricultural spraying and well below maximum residue levels in products presently approved in the European Union.

RALSTON, Iowa — Piglets hop, scurry and squeal their way to the far corner of the pen, eyeing an approaching human. “It shows that they’re healthy animals,” Craig Rowles, the owner of a large pork farm here, said with pride.

Mr. Rowles says he keeps his pigs fit by feeding them antibiotics for weeks after weaning, to ward off possible illness in that vulnerable period. And for months after that, he administers an antibiotic that promotes faster growth with less feed.

The Centre for Ecology and Hydrology looked at microscopic fungi in the soil that helps plants grow.

The study of nine farms in England, published in the journal Environmental Microbiology, found that organic farms have a much more diverse range of fungi living in the soil than on conventional farms.

Dr Christopher van der Gast, of the CEH, said the use of herbicides and pesticides, as well as constant tilling of the soil breaks down the fungi on intensive farms.
