Amid ongoing shifts in the world economic and political order, the promise for future public health is tenuous. Will todays economic systems sustain tomorrows health? Will future generations inherit fair access to health and health care? An important hope for the health of future generations is the establishment of a well-grounded, global public health system. Global Public Health: Ecological Foundations addresses both the challenges and cooperative solutions of contemporary public health, within a framework of social justice, environmental sustainability, and global cooperation. With an emphasis on ecological foundations, this book approaches public health principles-history, foundations, topics, and applications-with a community-oriented perspective. By achieving global reach through cooperative, community-based interventions, this text illustrates that the practical application of public health principles can help maintain the health of the worlds people. Blending established wisdom with new perspectives, Global Public Health will stimulate better understanding of how the different streams of public health can work more synergistically to promote global health equity. It is a foundation for future public health measures to be built and to succeed.
