If you haven't been ordering that double whipped Frappuccino at your local Starbucks with soy milk, you've likely been gulping down Recombinant Bovine Growth Hormone (rBGH). It makes cows produce more milk, but it's thought to increase the risk of breast, prostate, and colon cancer in humans (if only they could come up with something to make cows squirt machiatto directly from their udders).

But now, after two years of pressure from the organization Food and Water Watch, Starbucks has announced that it's going to go rBGH free by December 31, 2007.

Whew! Now you can guzzle that cinnamon dulce de leche latte with abandon (so long as you don't mind that growing coffee generally requires cutting down the rainforest, or that Starbucks busts unions).

Starbucks spokesman Brandon Borrman says the campaign had nothing to do with the decision.

"This decision was purely driven by our customers," Borrman said. "Increasing numbers of our customers were calling and asking us to do it, and the number of customers ordering organic milk was increasing, and we wanted to meet that demand."

Food and Water Watch spokesperson Jennifer Mueller noted that much of that activity (including 33,000 emails) was generated from call-in days conducted by her organization.

If you want to thank Starbucks CEO Jim Donald for not poisoning you with milk (or ask what "doppio" really means), you can reach the company at 1-800-235-2883.
