Article: Children and teenagers who spend lots of time in front of screens-especially TVs-are easier to get more weight as they age .according to a new study. The findings agree with research suggesting all that inactive sitting and always watching advertisements may lead to poor eating habits. Researchers used results from a long-term study of children Who took surveys every other year. Children were between ages 9 and 16 when the study started. Out of 4,300 girls in the Study. 17 percent were overweight or obese .Twenty-four percent of the 3 .500 boys were also above a healthy weight The surveys included questions about their height and weight as well as how much time they spent watching TV and DVDs and playing computer and video games. From one survey to the next, each one-hour increase in children's daily TV watching was in connection with an increase of about 0.1 points on a body mass index(BMI) , which measures weight in connection with height. That's a difference of about half a pound per extra hour of TV. "The weight of the evidence is so strong that television watching is connected with unhealthy changes in weight among youth,"says Jennifer Falbe . Who led the study while at the Harvard School of Public Health in Boston. "It's important for parents to know all the obesity-causing screens that really should be limited in their children's lives, Falbe says. " When children watch TV. There are many food advertisements on TV that might lead them to eat a cookie or drink a soft drink. " What's mare .she says . " You can get into a hibernating state on the sofa. Even if children are sitting down while playing a computer game. for example. they might be a bit more active."
Answer: Too much screen time leads to obesity.

Article: Nobody Benefits NEW YORK--America has been experiencing the longest economic increase in its history.Incomes have risen, unemployment has fallen, and cities such as New York are bursting with new office buildings. But just a short walk from Manhattan's skyscrapers, George Brown sits on the side-walk, cooking a lunch of rice and bits of fish over a can of cooking fuel. Brown is homeless -- one of the 2.3 million people in the US who end up on the street. During the day, Brown collects aluminium cans and sells them for five cents a piece.At night, he sleeps on the street. "I have been on the street about eight or nine years, something like that," said the 62-year-old former construction worker. Brown admits he's had problems with alcohol and has smoked cocaine.But he said he still wants a more stable housing arrangement.He could afford it just with the money he earns by collecting cans and small pieces of metal, if only truly low-income housing were available. However, he sees no hope of finding affordable housing in New York. With the strong economy and unemployment down, beautiful housing is being built to meet demand. A US report shows rents in New York city rose more than 27 percent between 1984 and 1999, from US $549 to US $700 a month. One of the side effects of the strong economy is that rents have been going up. The majority of people who experience homelessness really just need some affordable housing help. But few housing companies have been built for the poor.Many small apartments in the city now rent for US $1,500 a month or more. Brown, the homeless New Yorker, said he has a daughter who lives in the city but he rarely sees her.She is angry about his drinking and won't allow it in her house. Smiling, he said he also has seven grandchildren whom he'd like to see more often. "All I've got to do is clean up my act," he said.
Answer: Homeless and sleepless

Article: Pollutants coming from automobile operation have begun to cause many environmental problems. It has been calculated, for example, that 70% of the carbon monoxide , 45% of the nitrogen oxides , and 34% of the hydrocarbon pollution in the United States can be traced directly to automobile exhausts . In addition, rubber, motor oil and other materials accumulate on roadways and are washed into streams, with effects nearly as serious as those of untreated waste water. In an effort to improve the situation, the U.S. government has made regulations on the use of the constituents of automobile exhaust gas that are known to cause air pollution. These constituents fall roughly into three types: hydrocarbons that pass through the engine unburned; carbon monoxide, also a product of incomplete burning; and nitrogen oxides which are formed when nitrogen and oxygen are in contact at high temperatures. Besides their own poisonous character, hydrocarbons and nitrogen oxides react in the presence of sunlight to form harmful smog. Carbon monoxide and hydrocarbons are rather easily controlled by the use of higher burning temperatures in engines. Unfortunately, the conditions that produce minimum emission of hydrocarbons tend to raise emission of nitrogen oxides. In a way this difficulty is solved by adding recycled exhaust gas to the fuel mixture, thus avoiding the oversupply of oxygen that favors formation of nitrogen oxides. California, which has the most strict air-pollution laws in the United States, requires further special compounding of gas to control emissions, and several states have ordered that alcohol be mixed with gas, as this will reduce emissions of the carbon monoxide by 35 per cent and the hydrocarbons by 15 per cent.
Answer: Nitrogen and oxygen are put together in great heat.
