Hugh Pickens DOT Com writes "Mames McWilliams writes in the NYT that with California experiencing one of its worst droughts on record, attention has naturally focused on the water required to grow popular foods such as walnuts, broccoli, lettuce, tomatoes, strawberries, almonds and grapes. 'Who knew, for example, that it took 5.4 gallons to produce a head of broccoli, or 3.3 gallons to grow a single tomato? This information about the water footprint of food products — that is, the amount of water required to produce them — is important to understand, especially for a state that dedicates about 80 percent of its water to agriculture.' But for those truly interested in lowering their water footprint, those numbers pale next to the water required to fatten livestock. Beef turns out to have an overall water footprint of roughly four million gallons per ton produced (PDF). By contrast, the water footprint for "sugar crops" like sugar beets is about 52,000 gallons per ton; for vegetables it's 85,000 gallons per ton; and for starchy roots it's about 102,200 gallons per ton.

There's been some positive news in the last year (and the last few) for American cellphone customers: certainly there's more visible competition for their business among the largest players in the market. Nonetheless, the Wall Street Journal reports that while more competition may translate into some more attractive service bundles, flexibility in phone options, or smoother customer service, it doesn't actually mean that the customers are on average reaping one of the benefits that competition might be expected to provide: lower price. Instead, the bills for customers on the major wireless providers have actually gone up
, if not dramatically, in recent months — which means U.S. cell service remains much more expensive than it is in many other countries. The article could stand a sidebar on MVNOs
and other low-cost options, though -- I switched to one of these from AT&T, and now pay just under $40 for one version of the new normal of unlimited talk and text, plus quite limited (1GB) data, but still using AT&T towers. Has your own cost to talk gone up or down?Read Replies (0)
