The main idea of this project is to show the differences between two Europeancountries, Poland and Germany in their law structure about environment. This differences (ifthey are) may be caused by this, that Poland has joined European Community four years ago,and Germany is under Union’s law since it’s beginning, anyway, right now two of them aretogether under Union’s law, so in many ways they should manage the same. However, if you’lllook at the map, you can see that these two big countries are neighbours, so in some otherways they can be connected with themselves, also by lines of water, crossing through this partof Europe. It is good to show, how the governmets and people care about their naturalresources, that are very valuable in our times. The best way to show differences is to comparewater resources by numbers. That kind of informations can give a conclusion, what should bedone better and in what way, the science can help in decreasing water waste or pollution.
