空气污染 VS. 缺少阳光

(2014-10-31 05:19:39) 下一个

无事的时候,喜欢看和听 @北美崔哥调侃。在 ‘北美崔哥’的博客上,有一篇 "西雅图的蓝天白云!解放区的天,是明朗的天......"

有感于国内北京等地的空气污染,对比国外的空气质量,治理是需要时间,制度,措施,金钱和牺牲某些暂时利益的。请看下面一篇英文的关于伦敦在5060 年代的空气污染和照片:


Great Smog of 1952

The Great Smog befell London starting on December 4, 1952, and lasted until March of 1953. It was a great disaster that killed thousands and formed an important impetus to the modern environmental movement.

In early December of 1952, a cold fog descended upon London. Because of the cold, Londoners began to burn more coal than usual. At the same time, the final conversion of London's electric trams to diesel buses was completed. The resulting air pollution was trapped by the heavy layer of cold air, and the concentration of pollutants built up dramatically. The smog was so thick that it would sometimes make driving impossible. It entered indoors easily, and concerts and screenings of films were cancelled as the audience could not see the stage or screen.

Since London was known for its fog, there was no great panic at the time. In the weeks that followed, the medical services compiled statistics and found that the fog had killed 4,000 peoplemost of whom were very young or elderly, or had pre-existing respiratory problems. Another 8,000 died in the weeks and months that followed.

These shocking revelations led to a rethinking of air pollution. The disaster demonstrated to people around the world that it was a real and deadly problem. New regulations were put in place restricting the use of dirty fuels in industry and banning black smoke. These included the Clean Air Acts of 1956 and of 1968, and the City of London (Various Powers) Act of 1954.                                                

Despite clean air laws, smog persisted into the 60s.

六十年后的伦敦: 空气质量改善了,可是另一个问题发生了,一年中大概有78个月的时间见不到太阳,没有阳光,阴,miserable, 这种天气除了因缺少维生素D给身体带来的危害,对人精神上的伤害也不比呼吸到超过p.m 2.5标准500倍的空气的伤害小。有时候真有24小时生活在夜晚的感觉。所以,担心空气污染的,至少在没有雾霾的时候,你们还有阳光在作伴。

 

昨天伦敦地区太阳终于显现了,在这千载难逢之际,我无比的兴奋,照下了这几张照片:
