Arctic Tale (2007)
一部描写北极圈生物生活的电影。海豹和北极熊赖以生存的环境受到了人类活动导致北极冰雪融化的影响。旨在呼吁人们节约能源,减小温室气体排放,拯救环境。
如果说北京为迎接2008年奥运会而强制控制污染,为人类活动对环境研究提供了一次决好的机会的话,那么可以说这只是一个前奏。今天的经济危机可以说是更好的机会,大量生产企业倒闭,航班缩减,石油减产,在北极的科学家是否可以看到环境恶化的减缓或者是环境有所恢复。
如果我们看到了正面的结果,那么在环境政策上饱受批评北京政府终于有了一次成为正面榜样的机会。因为在北京奥运会后,政府看到了对私人车辆限行带来的环境改善,所以将长期限行车辆。在世界范围,我们就可以延续我们在经济危机中的节俭行为,减小对环境的影响。

北京环保局:景观模糊不代表空气质量不佳
-
杜少中借此提到BBC网站七月八日发表的照片,“类似的情况是其中一张照片颜色比较灰暗,用以说明北京的空气质量还有问题。我们的态度非常明确,北京的空气质量确实存在着需要进一步改善的问题,但是用照片去评价空气质量,这种办法是不科学的,因为照片作为视觉的作品产物,它不能反映空气质量的本质特征,需要用监测数据来显示,而不能用肉眼感觉。”
