Introduction. The material presented here is an attempt to indicate the meaning and the role of prosociality in individual biographies, but it also captures the problem in a much broader social dimension. The subjective review of concepts and approaches conducted allows us to treat prosociality as an essential topic of scientific discourse while seeing it as a challenge for pedagogical practice, with particular attention to the responsibilities of key educational environments - family and school. Aim. The purpose of this inquiry is to draw attention to the need for forming pro-social attitudes, as well as opportunities for specific educational environments in this process. Emphasizing the positive effects of pro-sociality and the possible negative consequences of its absence, an attempt was made to justify its impact on human (co)existence. Materials and methods. The text is an overview, based on reference analysis. Results. The presented material allowed us to demonstrate the importance and benefits of prosociality both for the functioning of the individual and for societies. Also, it indicates the important role of the family and school environment in building and promoting pro-social attitudes.
