The population as a global problem

Summary/Abstract: It is presented the problem about the human evolution while the homo-sapiens is a center among the ecological systems, shaked off the natural selection and performing demographic expansion, facing the challenges of its own reproduction as well. There are discussed the highest growth rates of population during the last three centuries and the danger of exhausting of resources for existing of today`s and future generations. The club of Rome is one of the first informal scientist`s group-signal giver about of this. It was indicated at the 70th of the 20th century by the method of systems dynamics the high growth rate of population of the developing countries and its stop have been recommended, while the UN undertook a multisided population program aiming the birth control and acceleration of the demographic transition in those countries (embracing at present 81% of the world population, about 7 bil. towards 2011). It is underlined that many versions are prepared about the future population growth and of the transition finalizing but nothing is been said about the post transition perspectives. Right in this connection the Bulgarian case has been presented as an example of fast transition without reaching stable population and jumping into negative natural growth while the lowing birth rates, increasing mortality and fast ageing are dominating – a process acquiring nature of crisis. A hypothesis is that the same model could be followed by the global population. This model considered by some Bulgarian scholars as fifth stage of the demographic transition, probably might lead to the end of the Homo sapiens existence. Avoiding of such perspective is to be among the key problems assigned to scientific researchers and considered as responsibility not only regarding the next generation, but the human being surviving on the planet.
