Children living in circumstances of social and economic disadvantage are at high risk for experiencing health problems caused or exacerbated by environmental factors. They are not only vulnerable to adverse chemical and physical factors in their environment, but often become trapped in the cycle of environmental health disparities due to low parental health literacy, limited social capital, and a lack of access to comprehensive healthcare and appropriate educational services. They will only be able to escape that cycle when children's environmental health becomes a priority and the resources, energy and creativity are amassed and allocated to address environmental health concerns. In this book, we look at issues concerned with the home environment, the school and the community. Investing in children's environmental health will prove cost-beneficial in the long run.
