Berridge, Virginia. (2016). Public Health: A Very Short Introduction. Oxford, United Kingdom. Retrieved from Oxford University Press.
As previously mentioned, the public health field is continuously evolving and growing. Berridge uses the beginning of this chapter to predict where the future of the public health field is headed and how far it has come since the beginning of public health. Main focuses are the improvements of life expectancy and the reduction of smoking rates. While environment is a factor of public health, and has improved over time, other factors remain issues within the field, such as vaccinations, diet, pollution, and more. Berridge reviews the beginning chapters of the book to compare the past and present within the public health field. Overcoming disease has been greatly accounted to progression of prevention methods to reduce public health risks, but now individual behaviors are being more examined and correlated to the environment and public health issues. Awareness on issues such as obesity is addressed and reiterated the fact that educating and informing are key to the public health field. In order for any field to grow, it is important to know its history, which is what Berridge tries to demonstrate through these chapters. Knowing the past can improve the present.
