The idea of Ecological Systems Theory was formed by the work of Urie Bronfenbrenner during 1940s on friendship patterns and childhood. For many years, several foundations were laid that led to the culmination of the ecological theory. Ecological theory was built in a nested structure that resembles Russian dolls. Urie Bronfenbrenner's ecological systems theory offers one approach to answer this question. He believed that a child's developed was affected by everything that was in the environment around them. There are five different levels of the environment according to this theory. 1. Microsystem. This is the environment that is closest to the child. Abstract. Through his Bioecological Systems Theory, Urie Bronfenbrenner emphasized school, parish, neighborhood, and other aspects of what behavioral geneticists now call the extra-familial environment.Bronfenbrenner incorporated even the economy, government, and culture into his developmental scheme, knowing that these macrostructural realities trickle-down to influence more local systems, if Urie Bronfenbrenner (1917-2005) developed the ecological systems theory to explain how everything in a child and the child's environment affects how a child grows and develops. He labeled different aspects or levels of the environment that influence children's development, including the microsystem, the mesosystem, the exosystem, and the According to Urie Bronfenbrenner, the environment in which a child grows up will shape and affect his or her development. He calls this environment the Ecological System. The Ecological System includes the physical, social, cultural, financial and religious environment in which the child matures and grows into an adult. Urie Bronfenbrenner (April 29, 1917 - September 25, 2005) was a Russian-born American psychologist who is most known for his ecological systems theory. His work with the United States government helped in the formation of the Head start program in 1965. Ecological theory, in particular the pioneering work of Urie Bronfenbrenner, has been influential in the field of Child and Youth Care. Ecological theory not only has deep and far reaching roots in the field, but also has the potential to influence new directions and development in Child and Youth Care. The goal of this literature review is to We describe the evolution, over three phases, of Bronfenbrenner's theory from an ecological to a bioecological theory. Phase 1 (1973-1979) culminated in the publication of The Ecology of Human Development (1979).Phase 2 (1980-1993) saw almost immediate modifications to the theory, with more attention paid to the role of the individual and greater concern with developmental processes. According to Urie Bronfenbrenner Each person affected by interactions among a number of overlapping ecosystems. • Child at the center of the model • Ecological systems are termed the social context of human development.

There are five levels of Urie's theory: Individaul, Macrosystem, Exosystem, Mesosystem, and Microsystem.
