School violence is a global concern with prolific consequences as a result of its lifelong psychological impact. Violence will continue to afflict human populations due to its underlying psychology, but this can be tempered by culture and other environmental factors. Violence is part of human nature. It has an evolutionary basis rooted in our biology and is expressed psychologically through behaviour, thinking and emotional expression. There are many forms, including physical and sexual assault, bullying and cyberbullying, public shaming, sexual harassment, suicidality, verbal and emotional abuse, and property theft. Although violence is ubiquitous, it is distributed disproportionally, as is obvious when considering demographics such as age, race, ethnicity, geographic location, socioeconomic status, gender, and environmental disparities (e.g. pollution, noise, and access to essentials). A prime example of environmental disparities is the current crisis affecting South Africa's electrical grid and its effects on behaviour. These facts reveal challenges that can be addressed to reduce violence overall and in specific settings, concomitantly reducing disparities and enhancing social justice. We address these issues from the bio-psycho-sociohistorical model (BPSHM) and provide recommendations for amelioration within the context of school violence in South Africa. While school violence is an increasing problem and challenge for all stakeholders, Nelson Mandela reminds us, "We owe our children -the most vulnerable citizens in any society -a life free from violence and fear."
