3.6 million people, that is almost 10 per cent of the population of Poland, live in the Upper Silesian Industrial District. From among this number more than 2.5 million live under the conditions where the admissible standards of environmental pollution, e.g. by benzopyrone, phenol heavy metals, etc., have been exceeded many times.
The elements and the general principles of the alternative economy in agriculture are discussed. Next, the organization and the productive as well economic resulst of one of the biodynamic farms in Poland are presented against the background of the conventional farm results.
Although there are many measurable advantages resulting from the chemicalization of agriculture, it arouses more and more objections because of the systematic pollution of the ecosystems.

It is a tradition by now that in May ecologists appeal to drivers to leave their cars in the garage for at leat one day. However, appeals of this type appear to be often ineffective.
