Here is the truth: The Earth is round; Saddam Hussein did not attack us on 9/11; Elvis is dead; Obama was born in the United States; and the climate … - Al Gore

Whether it is called a public forum or a public sphere or a marketplace of ideas, the reality of open and free public discussion and debate was considered central to the operation of our democracy in America’s earliest decades. Our first self-expression as a nation — “We the People” — made it clear where the ultimate source of authority lay. It was universally understood that the ultimate check and balance for American government was its accountability to the people. And the public forum was the place where the people held the government accountable. That is why it was so important that the marketplace of ideas operated independent from and beyond the authority of government. The three most important characteristics of this marketplace of ideas were the following: It was open to every individual, with no barriers to entry save the necessity of literacy. This access, it is crucial to add, applied not only to the receipt of information but also to the ability to contribute information directly into the flow of ideas that was available to all. The fate of ideas contributed by individuals depended, for the most part, on an emergent meritocracy of ideas. Those judged by the market to be good rose to the top, regardless of the wealth or class of the individual responsible for them. The accepted rules of discourse presumed that the participants were all governed by an unspoken duty to search for general agreement. That is what a “conversation of democracy” is all about.

The disruption of the world's ecological systems — from the rise of global warming and the consequent damage to our climate balance, to the loss of living species and the depletion of ocean fisheries and forest habitats — continues at a frightening rate. Practically every day, it becomes clearer to us that must act now to protect our Earth, while preserving and creating jobs for our people. And at the very same time that these threats are developing, the traditional nation-state itself is changing — as power moves upwards and downwards, to everything from supra-national organizations and coalitions all the way down to feuding clans. Susceptible to tyrants willing to exploit ethnic and religious rivalries, the weakest of these states have either imploded into civil war or threatened to lash out across their borders.
To meet these challenges requires cooperation on a scale not seen before. A realistic reading of the world today demands reinvigorated international and regional institutions. It demands that we confront threats before they spiral out of the control. And it requires American leadership — to protect our interests and uphold our values.

too little — and complex, because the manufacturing and marketing of food products has changed dramatically. Dr. David Kessler, former head of the U.S. Food and Drug Administration, has extensively documented how food manufacturers and restaurant and fast food chains carefully combine fats, sugar, and salt in precise ratios that reach the “bliss point” — which means they trigger brain systems that increase the desire to eat more, even after our stomachs are full. On a global basis, the World Health Organization has found a pattern of increased consumption of “energy-dense foods that are high in fat, salt and sugars but low in vitamins, minerals and other micronutrients.” Hyper-urbanization has separated more people from reliable sources of fresh fruit and vegetables. Quality calories in fruits and vegetables now cost ten times as much as calories per gram in sweets and foods abundant in starch. In a report for the Johns Hopkins Bloomberg School of Public Health, Arielle Traub documented the increase from 1985 to 2000 in the price of fresh fruits and vegetables by 40 percent, while prices of fats declined by 15 percent and sugared soft drinks by 25 percent.
