Literature Review Understanding social diversity is a key prerequisite to the development of human races. The appreciation of social diversity acknowledges that societies are composed of interrelated individuals and interdependent upon each other (Pallotta-Chiarolli 2001, p. 36). The dynamism of the society is a key factor to be considered in societies that societies are in a state of flux and change is rapid. In most societies individuals are unique, each has his/ her idiosyncrasies that can never be compared but just appreciated. Statistics indicate that most youth who are healthy and well educated are very competent in contributing to society despite their shifting in the world. Normally as indicated, the youth are the future of society (Sue 1997, p. 101). In Australia which is a multi-cultural society, about 16% of its youth are born from other countries while the non- English speaking backgrounds contribute to 24% of the youth in Australia (Pollack 1998, pp. 41). This, therefore, puts in a major challenge in youth health care due to the multicultural setting and diversity. The youth in their 20s are highly prone to diseases as well as risky behaviors due to their mentality of having to experience the world as it is their nature as the brain develops (Plummer 1999, p. 69). The interplay of cultures in Australia gives a major challenge to health professionals who have to be a culturally diverse group to enable proper interaction with the youth and their different families. Scientists, researchers, and clinicians are among the professional who must respect and promote culture, traditions, family backgrounds to enhance the health of a society. The greater population of youths in many countries are faced with situations and threats that are related to their health (Phillips 1993, p. 180). Health education and promotion among the youth are among the major concerns of many community-based organizations, research, and clinical studies aimed at improving youth health concerning cultural diversity. During the 1990s, the World Health Organization did a worldwide exercise on sustaining youth health that was based on an international legal framework based on the UN charter (Weidlich 2000, p. 47) However, the international demographic shift and policy check and the development of a program and research regarding the youth health was not absolute. This legal framework did not see the light of the day due to failed implementation. The twenty-seventh special session of the General Assembly in 2002 stated that the large majority of youth are faced with many problems worldwide but did not come with practical solutions. Among the problems included total insecurity, war, lack of occupation, family stress, sexual health problems, alcohol, drug abuse, mental health problems, HIV, and Tuberculosis. Most of these problems were faced by the youth who inhibited multi-cultural societies due to a lack of avenues of presenting their problems to the right experts at the right time. In trying to come up with solutions to this problem, one needs to apply a social diversity model which is appropriate. In this sense, the ecological systems theory developed by Bronfenbrenne analyzes child development in the context of systems relationship that comprises one’s environment (Allee 1942, p. 49). The interaction of a child’s immediate family and societal la
