Автор представил экологические обременительности, вытекающие с соседства ГДР. Хотя после соединения исчезнет главная причина экологического кризиса в ГДР, — недостаток средствий на предохранительные мероприятия, появятся новые опасности и новые шансы. Увеличится экспорт мусора и промышленных отбросов в Польшу, ценные экологически районы будут преобразованы для туризма с Немец. С другой стороны непосредственное соседство Общего Рынка может Польше доставить возможность навязания цивилизационных замедлений в области охраны среды.

The author presented the environmental disturbances stemming so far from the close neighbourhood of Poland and GDR. Although after the unification the main cause of the present environmental crisis in GDR — the lack of money for environmental protection investment — will cease to exist, there will be new worries and new chances. The export of garbage and industrial waste to Poland can increase, more of ecologically valuable areas will be converted to suit recreational needs of the rest of Germany. On the other hand bordering the EEC may help Poland in making time to reduce civilization backwardness, among others, in the field of environmental protection.

Unlike dunes, sandy beaches and the littoral zone are usually regarded as non-vulnerable. The biodiversity and biomass of interstitial organisms are low. How-ever, recent findings have shown that marine sands transfer energy very ef-fectively, and that chemical and biological reactions take place faster there than in fine-grained sediments. The importance of the microphytobenthos and bacteria to this system is little known. The effects of recreational pressure (trampling, beach cleaning and nourishment) are not well understood. A pilot study from the Baltic Sea shows the importance of trampling as a form of bioturbation, a very effective way of fragmenting and mixing organic matter with the sand. The high diversity of diatoms and meiofauna in undisturbed beaches may act as an effective biological filter for some types of pollutants, while less diverse, but more abundant biota in disturbed areas are more effective in processing organic matter (self-cleaning of the beach).
