From the green-house effect, global climatic change, acid rain, the hole in the ozone layer, destruction of the rain forests, conservation of animal and plant species in the wild, to desertification and the shrinkage of marine mammals, all of this was very little discussed and paid scant attention.
那時從溫室效應、全球氣候改變、酸雨、臭氧洞、雨林破壞、野生動植物的保護，到沙漠化、海洋生物匱乏現象…… 都還很少人討論，並未受到重視。
