...Difficulty of Comparing "Then" and "Now:" Davis is quick to note that historical data can sometimes be misleading, if not altogether inaccurate. Take early measurements of iron in foods: because scientists failed to sufficiently remove clinging soil, iron levels appeared unusually high in certain vegetables like spinach (which gave rise to the myth that it contained exorbitant amounts of iron - a notion further propagated by the popular cartoon character, Popeye). Then again, good historical data provides the only real-world evidence of changes in foods over time, and such data does exist - one farm in Hertfordshire, England, for example...
...Industrialization" of Agriculture: Thanks to the growing rise of chemical fertilizers and pesticides, modern crops are being harvested faster than ever before. But quick and early harvests mean the produce has less time to absorb nutrients either from synthesis or the soil, and minerals like potassium (the "K" in N-P-K fertilizers) often interfere with a plant's ability to take up nutrients. Monoculture farming practices - another hallmark of the Big Ag industry - have also led to soil-mineral depletion, which, in turn, affects the nutrient content of crops...
...prevent Taliban and al-Qaeda fighters maintaining sanctuaries in Pakistan from which they can launch attacks inside Afghanistan. But Pakistan's announcement on Monday of a peace agreement to accommodate the domestic Taliban insurgency in the Swat Valley suggests that an all-out war against militants on their soil is not what Pakistan's generals have in mind. And the supply lines that funnel food, fuel and war materiel to U.S. forces in Afghanistan, already imperiled by militant attacks in Pakistan, may face a further setback this week when the parliament in Kyrgyzstan votes on whether or not to kick...

In particular, Gulf countries such as the Emirates have tried to balance their allegiance to the Arab cause with developing themselves as modern, global centers for trade and tourism. Indeed, recently they've begun to allow Israelis to participate in sporting events on their soil. Last year, Peer, currently the 48th-ranked professional woman player in the world, competed in Doha, Qatar, becoming the first Israeli to be part of an officially sanctioned tennis tournament in the Arabian peninsula...
