臭氧层,人类最关注的环境问题之一,自1985年5月英国科学家首次在南极洲上空发现臭氧层空洞之后,又发现北极地区乃至北半球人口最密集的中纬度地区的臭氧层不断变薄并出现了季节性的空洞,从而威胁着地球村万物的生存,有识之士对臭氧层——“地球生物的保护伞”的漏洞百出,四面楚歌更是忧心忡忡。至今为止,科学界普遍认为臭氧层的耗损物质主要是包括氟氯烃在内的人为原因引起的,然而近年来的研究发现却表明,自然原因对臭氧层的耗损起着催化作用。 电子雨轰击说 据1987年美国《洛杉矶时报》报道,美国新墨两哥州国立洛斯·阿拉莫斯实验室的研究人员发现一 The ozone layer, one of the most important environmental issues for humans, has been discovered by British scientists since the discovery of ozone holes in Antarctica for the first time in May 1985. It has also found that the ozone layer in the mid-latitudes where the Arctic and even the most densely populated regions of the Northern Hemisphere are continuously thinning and seasonal. The hollows threaten the survival of all things in the global village. Well-informed people are full of loopholes in the ozone layer, the “protective umbrella of earth creatures,” and are surrounded with anxiety. So far, the scientific community generally believes that the depletion substances in the ozone layer are mainly caused by human factors including HCFCs. However, research findings in recent years have shown that natural causes play a catalytic role in the depletion of the ozone layer. Electronic Rain Bombardment According to the 1987 “Los Angeles Times” report, researchers at the Los Alamos National Laboratory in New Mexico and the United States discovered a
