翻译题46.On April 29th the Supreme Court ordered the next government to come up with a plan by the end of the year to reduce the amount of nitrogen dioxide (NO-2) in the atmosphere. The judgment could have big implications for several large infrastructure projects. It also suggests how dirty air is finally becoming a political issue. The health effects of NO-2 have not yet been calculated for Britain, but are thought to be as potentially damaging as fine man-made particulate matter, says Gary Fuller. A report from a government advisory group in 2010 estimated that, if all fine particulate matter were removed from the atmosphere, it would increase the average life expectancy of those born in 2008 by six months. Despite the mounting evidence of the harmful effect of dirty air, there has been little political desire to get it sorted. Politicians could often skirt the issue by pointing out that it was a Europe-wide problem.
