Having good social relationships -- friends, marriage or children -- may be every bit as important to a healthy life as quitting smoking, losing weight or taking certain medicines. U. S. researchers reported on Tuesday. People with strong social relationships were SO percent less likely to die early than people without such support, the team at Brigham Young University in Utah found. They suggest that the government look at ways to help people keep social relationships as a way of keeping the population healthy. "A lack of social relationships was equal to smoking up to 15 cigarettes a day," psychologist Julianne Holt-Lunstad, who led the study, said in a telephone interview. Her team conducted a study that examined social relationships and their effects on health. They looked at 148 studies that covered more than 308,000 people, published in the Public Library of Science journal PLoS Medicine at www.plosmedicine.org. Having low levels of social relationships was equal to being an alcoholic, was more harmful than not exercising and was twice as harmful as obesity. Social relationships had a bigger effect on early death than getting an injection to prevent pneumonia  ,than taking drugs for high blood pressure and far more important than living in air pollution, they found. "I certainly don't want to  _ these other risk factors because of course they are very important," Holt-Lunstad said. We need to start taking social relationships just as seriously. " But Holt-Lundstad said there was some evidence that assigning caretakers   does not help improve people's health. "Naturally occurring relationships may be different than the support received from someone who is hired for that purpose." she said. According to the text, having poor social relationships is as harmful as   _  . A) being fat B) staying up C) not doing sports D) drinking alcohol
(Answer)
D

There is a forgotten player in the global efforts to limit C02 emissions:the consumer. Households consume one--third of the final energy used in the European Union and produce around two--thirds of city waste.Moreover,food,housing,and private transport account for almost 80%of environmental pressures.So consumers can make a real difference when it comes to fighting climate change. Several factors can direct consumers towards more environmentally--friendly behavior. To achieve this,we need clear and simple information to guide consumption decisions. Indeed.Two thirds of consumers find it difficult to understand which products are better for the environment when shopping.  With 58% of Europeans believing that many companies pretend to be green in order to charge higher prices, industry has a long way to go in helping consumers feet confident when making green choices.They should give consumers more information about the carbon footprint of their products,and promote more sustainable behavior among their customers. To be sure, companies are increasingly creating product labels that help consumers make responsible choices--for instance, reminding users of products made from materials that are recycled,renewable, and/or less carbon--intensive.  Even so,only,20%  of Europeans believe that companies are doing enough to promote environmentally friendly options. In times of crisis, consumers prefer high-quality products that will last long and won't go out of style.Durable products might sometimes cost more, but they don't need to be replaced as frequently. In this way,companies that create durable or recyclable products enable consumers to think differently about their purchases, which can help users behave more responsibly, and thus may help end our "throw-way" culture. However,  it is not enough to inform consumers of the environmental features of products. We also need to provide consumers with guidance to establish a practical lifestyle model to follow. This cannot be brought about by regulations alone, but by... The author advises companies to  _  in the time of crisis. A) reduce the cost of production B) throw away old models C) replace their products frequently D) make more durable products
