In the 1970s, the ecosystem functions as services began the utilitarian draughting, according to the attention of the public opinion at biodiversity and the environment protection. With the passing or some decades, the literature of the ecosystem services applied different estimates to the economic value of the single natural components. An international gathering was the result of this process (Millennium Ecosystem Assessment), where the participations reached an agreement about that the ecosystem services are necessary to deal with on a daily level. 24 pieces of ecosystem services were defined in the course of the synthesis, which content of consider only 4 (I) show an improvement, 15 services decline seriously, while 5 ecosystem services show stability. In the 2000s ecological services came into the foreground, through economic decision making until the maintenance of devices with a market basis entirely, and then in its logic so was born the Payments for Environmental Services. In my study I inform the story of ecosystem services, deviating to the important stations and the different prevailing economic views. It's important to recognize that the concept of ecosystem service show took shape and manifested itself in its today's form. In the next chapter I inform the PES conceptual definition, because a number question arises defining a concept with itself Wunder's definition appeared in 2005 rather can be considered for a general guiding, what the representatives of the different directions modify according to their own taste in the mouth. I discuss the scope of problems of the efficiency, equity and poverty on the end of the study, because these three topics are some economic, indeed ecosystem service and in connection with PES all the time recurring phenomenon.
