Therefore environmental studies are of great importance to public health .the air we breathe, water that we drink, and the interaction which is complex between humans and the surrounding. Environmental studies help us understand how the build as well as the natural environment can influence the health of people in a community. It also helps us understand how the risk factors that cause certain diseases can be reduced. The environmental; risk factors can lead to development of diseases such as cancer, asthma and food poisoning. Due to incorporation of chemistry, engineering and toxicology in environmental studies there can be combined expertise that will help in answering public health related questions. Environmental health which is a discipline of both public health and environmental studies can be divided into various aspects like water quality, noise control, air quality, food protection, management of solid waste and so on. All these are important aspects that contribute to public health (Association of Schools of Public Health, 2013). Biostatistics and public health

Biostatistics entails the development and application of methods...

Using biostatistics one can identify health trends which can eventually be instrumental in development of life saving measures through applying procedures, techniques and methodologies of statistics. Biostatistics can also be used in the forecasting of scenarios, identifying trends in health that are found in a particular community, the explanation of certain biological phenomena, determining causes of injury and diseases and so on. Biostatistics forms an integral part of public health (Association of Schools of Public Health, 2013).
