US Signs Global Tobacco TreatyThe United States has taken the first step toward approving a global tobacco treaty that promises to help control the deadly effects of tobacco use throughout the world. Health and Human Services Secretary Tommy Thompson signed the Framework Convention on Tobacco Control (FCTC) this week at the United Nations. 1 The FCTC was developed by the World Health Organization and approved by members of the World Health Assembly, including the United States, last year. 2 For instance, cigarettes sold in those countries would have to have health warnings on at least 30% of the front and back of every pack. 3 It also requires bans on tobacco advertising, though there are some exceptions for countries like the United States, where the Constitution prohibits such an outright ban. 4 The World Health Organization estimates that tobacco use kills nearly 5 million people worldwide every year. In the US alone, about 440,000 people die each year from tobacco-related illnesses; about one-third of all cancers in the US are caused by tobacco use. If current trends continue, WHO estimates, by 2025 tobacco will kill 10 million people each year.The treaty must be ratified by at least 40 countries before it can take effect. 5 A. The impact of the treaty could be huge.B. Countries that ratify (批准) it would be required to enact strict tobacco control policies.C. The treaty calls for higher tobacco taxes, restrictions on smoking in public places, and more promotion of tobacco prevention and cessation programs.D. So far, 109 countries have signed it, and 12 have ratified it.E. The Senate must still approve the treaty before the US can implement its provisions.F. Tobacco stocks also perked up as investors discounted fears of litigation (诉讼) from the US.
Feed the World with Potatoes1 As food prices continue to rise rapidly, there is growing concern about the effect it will have among the world"s poor.2 Increasingly, experts are looking to the potato as a possible low-cost solution to feeding the hungry. To emphasize the issue, the United Nations has called the potato "a hidden treasure", and named 2008 the International Year of the Potato. Here"s how potatoes could end the food crisis.3 The potato matures more quickly, on less land and in harsher climates than most other major crops. Up to 85 percent of the plant is eatable, compared with around 50 percent of cereals. Its broad adaptability to a wide variety of farming systems is also noteworthy.4 Potatoes are an excellent source of complex carbohydrates ( 碳水化合物), which release their energy slowly, and have only 5 percent of wheat"s fat content. They contain only a quarter of the calories of bread and, according to the Potato Center, when boiled, potatoes have more protein and nearly twice the calcium (钙) as corn. Additionally, they are good sources of vitamin C, iron, potassium (钾) and zinc (锌).5 The Food and Agricultural Organization recently surveyed food price inflation in over 70 of the poor countries. Cereal price inflation was much higher and far more widespread than for potatoes. A significant factor behind the potato"s affordability is the fact that unlike other agricultural products, the potato is not yet a global commodity, and has therefore not attracted speculative investors. Raw potatoes are heavy and can rot during transit, so global trade has been slow to take off. Also, potatoes are susceptible (易受影响的) to infection with disease, hindering (阻碍) export. According to analysts" estimates, less than 5 percent of potatoes are traded internationally, with prices driven primarily by local tastes instead of international demand. The whole world is concerned about food prices because ______.
