That is why this paper is dedicated, in more detail, to the analysis of agriculture, because of its importance in the life of bee colonies. Through this paper there are also explanations of the consequences of the disappearance of bees globally included in the analysis are the entire world and the European Union, which are directed towards the accelerated development and production based on only one goal - achieving the greatest possible profits.
