A new study has identified pollution as the world’s No. 1 killer. Study organizers say pollution is responsible for more premature deaths than war, (1) , natural disasters, smoking and disease. By premature death, the researchers mean dying before the average age of death within a population group. Many of these deaths can be (2) . A report on the study was published in the medical journal Lancet. The researchers looked at pollution levels, both inside enclosed buildings and in the world around us. They (3) that pollution killed about 9 million people in 2015. That would (4) one of every six deaths worldwide. Karti Sandilya helped to prepare the report. He said “Pollution (5) fundamental human rights, such as the right to life, health, well-being, safe work as well as protections of children and the most (6) .” The report said the large majority of pollution-related deaths take place in developing countries. The researchers say leaders in those countries are more concerned about building their economies and public services than environmental (7) . Some of the most affected countries are Bangladesh, China, Haiti, India, Pakistan, North Korea and South Sudan. But Richard Fuller, another writer of the report, said pollution is tied to slow economic development in both rich and poor nations. He said “There is this myth that finance ministers still live by, that you have to let industry pollute or else you won’t develop. What people don’t realize ... people who are sick or dead cannot (8) to the economy. They need to be looked after.” The report said that 9 million premature deaths a year is only a(9) estimate. It says the actual number is likely to be much higher. A separate study by the World Bank said reducing pollution must be a top goal. It says that solving this problem would lead to solutions to other crises, including (10) and rising temperatures on Earth’s surface. I’m Jonathan Evans.

| One of the greatest killers in the Western world in heart disease. The death rate (率) from the disease has been increasing at an alarming speed for the past thirty years. Today in Britain, for example, about four hundred people a day die of heart disease. Mdical experts know that people can reduce their chances of getting heart disease by exercising regularly, by not smoking, by changing their diets, and by paying more attention to reducing stress (压力) in their work. However, Western health-care systems are still not paying enough attention to the prevention of the disease. There is a need for more programs to educate the public about the causes and prevention of heart disease. Instead of supporting such programs,however, the U.S. health-care system is spending large sums of money on the surgical (外科的) treatment of the disease after it develops. This emphasis (强调) on treatment clearly has something to do with the technological advances that have taken place in the past ten to fifteen years. In this time,modern technology has enabled doctors to develop new surgical techniques. Many operations that were considered impossible or too risky (有风险的) a few years ago are now performed every day in U.S.hospitals. The result had been a huge increase in heart surgery. Although there is no doubt that heart surgery can help a large number of people, some people point out that the emphasis on the surgical treatment of the disease has three clear disadvantages. First, it attracts interest and money away from the question of prevention.Second, it causes the costs of general hospital care to rise. After hospitals buy the expensive equipment that is necessary for modern heart surgery, they must try to recover the money they have spent.To do this, they raise costs for all their patients, not just those patients whose treatment requires the equipment. The third disadvantage is that doctors are encouraged to perform surgery-even on patients for whom an operation is unnecessary-because the equipment and expert skills are there. A government office recently stated that major heart surgery was often performed even though its chances of success were low. In one type of heart surgery, for example, only 15 percent of patients improved their conditions after the surgery. However,more than 100,000 of these operations are performed in the United States every year. |
