西德是世界上工业最发达的国家之一。根据近年来的调查资料,大气污染所造成的危害已达到难以想象的地步,其中对森林的危害要比其它原因严重得多。北来因——威斯特伐利亚洲的杉林有58％面临死亡的威胁,黑森州有3,000公顷森林染上了严重的污染病害,巴伐利亚洲及附近地区有5.5万公顷森林已濒临毁灭的边缘。慕尼黑附近地区的100年生的杉林感染污染病害后两星期全都死亡。巴登——符腾堡州也有6.4万公顷冷杉林染上了病害。令人担心的是,大气污染给衫林带来的灾害有可能蔓延到北部地区。这种局面一旦出现,占西德森林(290亿株)近三分
West Germany is one of the most industrialized countries in the world. According to recent surveys, the damage caused by air pollution has reached an unimaginable level, and the damage to forests is far more serious than any other cause. 58% of the cedars in North Rhine-Westphalia are under threat of death, 3,000 hectares of forest in Hesse is heavily polluted and 55,000 hectares of forest in and around Bavaria are on the brink of destruction edge. The 100-year-old cedar forest in the area near Munich died after two weeks of infectious disease. There are also 64,000 hectares of fir forest in Baden-Württemberg infected with the disease. What is worrying is that the air pollution caused to the forest forest disaster may spread to the northern region. Once this situation appears, it accounts for nearly one-third of the forest in West Germany (290 billion plants)
