主播大秀

A foreign currency shortage is making life difficult for Nigerian businesses. The 主播大秀's Martin Patience in Lagos tells us what the government is doing to try and shore up confidence. Also in the programme, we report from the world's most polluted city, Delhi, on efforts to improve air quality by imposing restrictions on car use. And Jos Dings of the sustainable transport think tank Transport and Environment assesses efforts around the world to try and steer people away from car use on pollution grounds. We have a report from Finland on strategies to reduce the health impact of radon gas, which can accumulate in the country's well-insulated homes and offices. Plus television director and producer Francis Hanly tells us how George Martin, who became known as the Fifth Beatle, changed the face, and sound, of the music business.
