Progress in Soil Zoology: Proceedings of the 5th International Colloquium on Soil Zoology Held in Prague September 17-22, 1973 (Transactions of the Prague Conferences on Information Theory)

Description

Ladies a n d g e n t 1 e m e n, I have the pleasure to welcome you here in Prague in the name of the Czechoslovak Academy of Sciences and to open the Fifth Inter- national Colloquium on Soil Zoology. We are very glad that Czecho- slovakia was chosen for this important meeting. It is clear to all of us that the soil plays and will play a de- cisive part in providing food for the explosive increase of human pop- ulation. For this reason we watch with great anxiety the negative influence of human activities on the environment accompanied also by the other destructive intervention into the soil ecosystem, its devas- tation by inefficient management, application of herbicides and pesti- cides pollution by the waste products of industry and human settlements. The basis for solving these accumulating and now sometimes latent prob- lems is among others a good knowledge of the role of soil organisms in the cycles of materials and in the energy flow. Soil zoology as a part of soil biology is still at the beginning of this trend The lack of in- formation about life in soil is obvious when compared with the results of a related biological science dealing with the water ecosystem.
