grey, daily, but none the less urgently to be solved ones, too. Through the eyes of the biologist, the world had enormously altered in the last decades, and this transformation continues even more rapidly in the future.The essence of this transformation may be stated biologically to consist of the fact that man is bound to utilize in always greater rates the biological production of the Earth. It is almost a truism that every living animal and man sustain themselves, directly or indirectly, on plants. An increase of productive areas, the development of agrotechnics, plant and animal husbandry are yet able to boost useful biological production, - but the up-to-date /or traditional/ production still has its upper limits. The situation changes radically, if we consider the new, revolutional , vistas of biological energystoring. The prospective results of algal biology and chlorophyll synthesis are examples of such possibilities.Certain microscopic algae are able to surpass many times and in the same time, the photosynthetic production of „traditional" plants. It is not impossible that, by the complete solution of the problems of chlorophyll synthesis , we shall one day be able to conjure photosynthesis in vitro. In this case man may make himself independent of green plants, to utilize the illimitable energy of the Sun in the production of his food. This possibility is, however, still utopistic, and the biologist of today should rather have the task to augment „traditional" biological production. In conclusion, I should therefore like to outline the aims of biocoenology . It is clear to all soberly thinking men that the agricultural development of the world, the same in the west as in the east, tends to switch over to mechanized agricultural mass-production. This new kind of operation imposes freshtasks on both plant protection and soil biology. Large-plot culture, by its lack of intersecting areas, to wit ,paths ,weedy margins, mosaic fields, fosters the birth
