In Bykovsky, a village of 457 on Russia&39;s northeast coast, the shoreline is collapsing, creeping closer and closer to houses and tanks of heating oil, at a rate of 15 to 18 feet a year.
"It is practically all ice - permafrost - and it is thawing." For the four million people who live north of the Arctic Circle, a changing climate presents new opportunities. But it also threatens their environment, their homes and, for those whose traditions rely on the ice-bound wilderness, the preservation of their culture.
A push to develop the North, quickened by the melting of the Arctic seas, carries its own rewards and dangers for people in the region. The discovery of vast petroleum fields in the Barents and Kara Seas has raised fears of catastrophic accidents as ships loaded with oil and, soon, liquefied gas churn through the fisheries off Scandinavia, headed to markets in Europe and North America. Land that was untouched could be tainted by pollution as generators, smokestacks and large vehicles sprout to support the growing energy industry.
Coastal erosion is a problem in Alaska as well, forcing the United States to prepare to relocate several Inuit villages at a projected cost of $100 million or more for each one.
Across the Arctic, indigenous tribes with traditions shaped by centuries of living in extremes of cold and ice are noticing changes in weather and wildlife. They are trying to adapt, but it can be confounding.
In Finnmark, Norway&39;s northernmost province, the Arctic landscape unfolds in late winter as an endless snowy plateau, silent but for the cries of the reindeer and the occasional whine of a snowmobile herding them.
A changing Arctic is felt there, too. "The reindeer are becoming unhappy," said Issat Eira, a 31-year-old reindeer herder.
Few countries rival Norway when it comes to protecting the environment and preserving indigenous customs. The state has lavished its oil wealth on the region, and Sami culture has enjoyed something of a renaissance.
And yet no amount of government support can convince Mr. Eira that his livelihood, intractably entwined with the reindeer, is not about to change. Like a Texas cattleman, he keeps the size of his herd secret. But he said warmer temperatures in fall and spring were melting the top layers of snow, which then refreeze as ice, making it harder for his reindeer to dig through to the lichen they eat.
"The people who are making the decisions, they are living in the south and they are living in towns," said Mr. Eira, sitting inside his home made of reindeer hides. "They don&39;t mark the change of weather. It is only people who live in nature and get resources from nature who mark it."

Questions 6 to 10 are based on the following passage:
？？The poverty line is the minimum income that people need for an acceptable standard of living. People with incomes below the poverty line are considered poor. Economists study the causes of poverty in order to find solutions to the problem.
As the general standard of living in the country rises, the poverty line does, too. Therefore, even with today&39;s relatively high standard of living, about tenpercent of the people in the United States are below the poverty line. However, if these people had stable jobs, they could have an acceptable standard of living. Economist ssuggest several reasons why poor people do not have jobs.
For one thing, more than half of the poor people in the United States are not qualified to work. Over 40 percent of the poor people are children. By law, children less than 16 years old cannot work in many industries. A large number of poor people are old. Many companies do not hire people over 65 years old, the normal retirement age.
Some poor adults do not look for jobs for avariety of personal reasons: they are sick, they do not have any motivation, they have family problems, or they do not believe that they can find a job.
Other poor people look for a job but cannot find one. Many poor adults never went to high school. Therefore, when they look for jobs, they have few skills that they can offer.
At the present time, the government thinks it can reduce poverty in the country in the following ways. First, if the national economy grows, businesses and industries will hire more workers. Some of the poor who are qualified to look for jobs may fund employment. Then they will no longer be below the poverty line.
Second, if society invests in the poor, the poor will become more productive. If the government spends money on social programs, education, and training for poor people, the poor will have the skills to offer, and then it is more likely that they can find jobs.？？
Finally, if the government distributes society&39;s income differently, it will raise some poor people above the poverty line. The government collects taxes from the non-poor and gives money to the poor. These payments to the poor are called welfare. In 1975 over 18 million people in the United States received welfare.
Some economists are looking for better solution to the poverty problem. However, at the present time, many people depend on welfare for a minimally acceptable standard of living.
