[Q]: Article: Have you ever imagined what the world will be in the near future? A recent study shows that the world in 2100 will be more crowded, more polluted and less stable ecologically than the world we live in now. Visible ahead is serious stress involving population, resource and environment. Despite greater food output, people in the world will be poorer in many ways than they are today. For hundred of millions of the extremely poor, the outlook for food and other necessities of life will be no better, for many it will be worse. While the economies of the developing countries are expected to grow at a faster rate than those of the industrialized nation, the total national product per head in most less developed countries remains low. The existing gap between the rich and poor nations will further widen. World food production is estimated to increase by 90 percent from 2000 to 2100. Most of that increase goes to the countries that already have higher per-head food consumption. Meanwhile, per-head consumption of food in the developing countries will scarcely improve or will actually fall far below the present inadequate level. What is worse is that prices for food are expected to double. As a result, many less developed countries will have increasing difficulties meeting energy needs. For the one quarter of mankind that depends primarily on wood for fuel, the outlook is not hopeful. Regional water shortage will become more sever. In the 1970-2100 period population growth will require twice as much water as it does today in nearly half the world. Still greater increases would be needed to improve standards of living. Development of new water supply will become more costly.

[Q]: Article: Wine drinkers tend to buy healthier food than beer drinkers, according to a Danish study published on Tuesday on the website of a weekly medical magazine. People who bought wine at the store were also more likely to buy fruit, vegetables, fish, lean meat and milk than beer buyers did, said the study. Beer buyers were more likely to buy frozen dinners, cold cuts, pork, sugary products, and soft drinks. The study was conducted by four researchers from the National Institute of Public Health over the course of six months. Alcohol researchers Erik Schulenburg and Marten Greenback and two other doctors collected 3.5 million receipts from 98 stores. The customers at the stores represented a large number of Danish people, they said. "Our results confirm international studies which show that wine drinkers tend to eat more fruit, vegetables and fish and rarely eat fats, compared to those who like other kinds of alcoholic drinks," they concluded. Wine buyers also tended to have higher education levels, higher earnings and be in better mental health, they added. Their interest in consumers' shopping bags followed a series of studies in the Danish media. The studies suggested that wine drinkers ran a lower risk of cardiovascular disease and some types of cancer than beer drinkers.
