Pоisоn fоr Dinner A Spies, secrecy, revenge, motives for murder—these hаve аll been аround for hundreds, if not thousands, of years. And poison is one of the most manipulative ways for people to get what they want. B In Renaissance Italy (from the 14th to 16th centuries A.D.), poison was commonplace. "Poison was the solution to delicate political problems," says Paolo Preto, a professor of modern history at the University of Padua. A touch of poison added to the wine would not cause suspicion (autopsies were rare at the time) and much less messy than using a knife or gun. Allegations were hard to prove, and innocence was difficult to dispute. C The Borgias—Alexander VI and his son Cesare—specialized in faith-based poisonings. As Pope, Alexander appointed wealthy candidates to be bishops and cardinals, allowed them to increase their riches, and then invited them to a grand dinner. The house wine, with just a bit of arsenic, killed the guests. Their wealth, by church law, then went to their host, the Pope. English essayist Max Beerbohm wrote: Though you would often in the 15th century have heard the snobbish Roman say, “I am dining with the Borgias tonight,” no Roman ever was able to say, “I dined last night with the Borgias.” D More recently, poison, dioxin to be exact, was the lead player in the drama of Ukrainian president Viktor Yushchenko, victim of an attempt to remove him from the political scene. In the United States, similar secret plots became the subject of investigations after the early 1960s, when the elimination of Cuban dictator Fidel Castro was a top priority. Some plans that are said to have been considered but then rejected included the delivery of a box of botulinum-soaked cigars, contaminating Castro's scuba breathing apparatus with tubercle bacilli, or sprinkling his shoes with thallium salts in hopes that hair loss, one of the common side effects of thallium absorption, would make his beard fall off. E Frankly, with all of this poison, people in high positions have had compelling reasons to watch what they eat. Mithridates, King of Pontus and enemy of Rome, tested poison antidotes on prisoners and ate a mix of 54 ingredients to protect himself against poisoning. An armed guard brought dinner to the table at the court of Louis XIV, and Columbus carried dogs on his second voyage to taste foods that natives of newfound cultures brought him and his crew. And it’s no wonder that for centuries, kings and queens have employed a very important person: the food taster. A food taster eats the food before the king, and then they watch for symptoms. If the taster lives, the king eats. F For three generations, the family of Mathura Prasad held the position of food taster to the thakur, or lord, of Castle Mandawa in India's Thar desert. "Food was kept under lock and key," he recalls. Before entering the kitchen, "the cook would bathe and change into different clothes. Guards would check his pockets and turban to make sure he wasn't hiding anything. Only then would he be allowed in. When the food was ready, some from each dish would be fed to a dog. Next I would taste, then the guards. The food would go to table under armed escort. Several trusted generals would test it. Finally, the lord and his guest would exchange bits of each dish. Just in case." G Food tasters have ceased to be part of every dinner party at Castle Mandawa, which is now a hotel. But recently, when the vice president of India came to lunch, a food taster sampled the food. Just in case... H These days, employment opportunities for tasters are in decline. In England, Buckingham Palace reports there is no formal procedure for food tasting. "The in-house help are fully vetted," a palace spokesman says. The Japanese emperor hasn't used a food taster in years. In the state kitchens of Thailand, humans are factored out altogether. There, the taste-test heroes of the banquet table, directed by the Ministry of Health, are a group of white mice.

Whо Owns the Wаter? A Blue gоld. These wоrds reveаl how precious this nаtural resource is to us and how fundamental it is to human survival. The debate rages on over who owns, or should own, water, but few people would disagree that plentiful sources of fresh water on Earth are disappearing. Maude Barlow, chairperson of the Council of Canadians, a consumer group, is dedicated to ending the private ownership of the world's water. As part of her struggle to have water declared a basic human right, Barlow has written the book Blue Gold: The Fight to Stop the Corporate Theft of the World's Water. She has also contributed to the essay collection Whose Water Is It? published by National Geographic Books. Barlow offers insights into this important issue. B Barlow says that water problems are evident in many different parts of the world. She notes that 22 countries in Africa are without safe drinking water because people simply have no access to it, and that South Africa in particular is in very serious trouble. Latin America is slightly different. Although it has enough water, in many places ordinary people can't get access to it unless they have money. Barlow also believes that China is paying for its efforts to become an economic superpower by making the colossal mistake of destroying its own water tables. Two-thirds of the cities in northern China are now severely lacking in water supplies. Eighty percent of all of China's rivers and waterways are polluted beyond use and too hazardous for consumption; 75 percent of India's are the same. C There are two reasons water doesn't reach people. One is that natural sources are running out. The other is that people who can't pay aren't able to get it. Barlow says Latin America is a good example of a place that has a plentiful basic water supply and there is overall enough water for everyone. However, she says, it doesn't get to all the people. She maintains that in this part of the world it's more about politics, about who can pay, than about scarcity. In the dry Middle East, however, the demand for water has surpassed supply. And in some places like South Africa, the problem involves a little bit of both issues. There's not enough water there, but the rich have access to as much as they want. It's very cheap, and they're willing and able to pay for it. However, the poor don't have any water at all. D Barlow goes on to describe another important water issue: commodification. She says there are several ways whereby water is commodified. The first is through the big service companies that have moved into the areas of water service, supply, and treatment to build profits. Barlow doesn't have any problem with the private sector building infrastructure. However, she feels it's crazy to take something that is needed for life, like fresh water, and allow private companies to divert it to a for-profit business. Second, there is the bottled-water industry, which makes billions every year and is still growing an estimated 15 to 20 percent a year. The third area where the commodification of water is occurring is in the large-scale commercial export of water. E Barlow is deeply opposed to commodification because water is necessary for life and there is no substitute for it. She feels there are some areas of life that should be off limits to commodification. She says that current water commodification practices should be modified or banned entirely. Water, she maintains, is probably the best example of something that should be kept outside the marketplace, a guaranteed right for all people.
