| 内容記述 | Using the internet, newspaper articles concerning environmental problems during the past 12 years were found. The number of articles was then compared to the latest trend of standing dead trees in order to determine the year on year correlation. The results are summarized as follows : The number of articles concerning environmental problems and the air pollution remarkably increased during the period of the 1988～1992. The number concerning these two matters increased again in 1997 and 1998,though the number of articles decreased for 1993～1996. The number of articles concerning acid rain showed a similar tendency, but decreased in 1998. On global warming, the number of articles greatly increased in 1997 and 1998. By contrast, the number of articles concerning the disruption of the ozone layer decreased, although this problem became much worse. In 1992,however, it peaked in number. This same tendency also appeared in the change of consciousness in students. On the other hand, the problem of the disruption of forests in which they are very interested is not often covered in newspaper article. The continual information concluded what the present situation is, not temporary one, is desired. As for standing dead trees, there seem to be many causes according to place, different kind of tree and so on. The effect of acid rain has also been considered. In Nikko, areas in which there are standing dead trees reached 2500ha in 1996 and is extending into Nikko and Tanzawa. Investigations into the causes and ways to protect trees are now under way. Recently, research into the effects of acid rain on trees has increased. | |||||||||||
