問題詳情：

Around 2 million schoolchildren in schools right across the country are taking part in one of the most important dates, as Monday 21 May saw the start of Walk to School week.

   The national event was held at a school in Lambeth. Lots of people gathered around a very big globe, the size of which shows the volume（體積）of carbon dioxide produced by a school bus every week. Similar events were held at schools throughout the country, making sure the message gets out all over Britain.

   And it is not just about the climate-change-causing carbon dioxide. As for local air pollution, the school bus is one of the worst offenders. It’s those short, stop-start journeys which are the most polluting — giving out carbon dioxide and other compounds（化合物）that are linked to worsening air quality.

   Contrary to what some might believe, staying in a car offers no protection from local pollution — in fact pollution found inside the car is about three times higher than that experienced by walkers. The organizers ask people to leave those keys by the door and walk to school — and judging by the number of schools involved（參與）this year it’s the schoolchildren that will be leading the way.

    Andrew Fielding, one of Walk to School organizers, said, “We’re encouraging people around the country to use Walk to School week to try out walking with their kids. Walking to school isn’t just great for the environment, it’s great for you too — walking for those 30 minutes a day means real quality time together, and the average walk there and back will burn more calories（卡路里）than those burnt in the school’s PE. Give it a go and see how you find it, and we doubt if you’ll want to go back to the traffic jams afterwards!”
