Even critics of World Water Week, held annually in Stockholm, Sweden, agree that it's an important forum where thousands of people working on water issues share information.

This year's event, held from August 16 to 22, placed special emphasis on the relationship between water and climate change. The closing statement (pdf) was literally a message to COP15, the major United Nations Framework Convention on Climate Change meeting in Copenhagen, Denmark, this December. "Water is a key medium through which climate change impacts will be felt," it reads, adding that "water-related adaptation" should be seen as part of the solution. The statement also calls for funding "to assist vulnerable, low income countries already affected by climate change," along with longer-term adaptation efforts.

So why are there critics of World Water Week? In a word, Nestlé.

Saturday, August 29 I had the good fortune to speak at a community rally for health care reform in a city park in downtown Portland, Oregon. It was a broad-based and diverse group with many signs and placards supporting the 'public option' being debated by Congress, and others calling for 'single payer' reform like that working effectively in other countries such as Canada. Here is what I said:

I would like to begin by apologizing to all of you for the role I played 15 years ago in cheating you out of a reformed health care system. Had it not been for greedy insurance companies and other special interests, and their army of lobbyists and spin-doctors like I used to be, we wouldn't be here today.

I'm ashamed that I let myself get caught up in deceitful and dishonest PR campaigns that worked so well, hundreds of thousands of our citizens have died, and millions of others have lost their homes and been forced into bankruptcy, so that a very few corporate executives and their Wall Street masters could become obscenely rich.

Fake "grassroots" groups have started springing up like toadstools after a rain, and this time they're coming at us from every angle: they're on TV, Twitter, Facebook and YouTube: "Americans for Prosperity," "FACES of Coal, "The "Coalition to Protect Patients' Rights," "Americans Against Food Taxes," the "60 Plus Association," "Citizens for Better Medicare," "Patients First" ... It's making our heads spin! Issues affecting some of the country's biggest industries, like health insurance reform, a proposal to tax sodas and sugary drinks, and the FDA's possible reconsideration of the plastic additive Bisphenol A, have boosted corporate astroturfing up to a dizzying pace. With all these corporate fronts coming out of the woodwork, how can citizens tell true grassroots organizations from corporate fronts operated by highly-paid PR and lobbying firms? Here are some tips to help readers spot this kind of big-business hanky-panky.
