WHO officials say nearly three billion people are unable to use clean fuels and technologies for cooking, heating and lighting. And they say more than seven million people die from exposure to indoor or outdoor air pollution each year. Of that number, the WHO says about 4.3 million people die from household air pollution given off by simple biomass and coal cook-stoves. Most of the deaths are in developing countries.________________________ 世界卫生组织官员说,有将近30亿人不能用上清洁染料和技术做饭,取暖和照明.他们还表示每年超过7百万人死于室内外的空气污染,其中大约430万的人死于生物燃料和煤炉释放出的室内空气污染. 大部分死者都在发展中国家.______________________
