Biological Processes Impact on Public Health

Biological processes have critical effects on the maintenance of the earth organism’s existence, and the changes in these biological processes may have gross disruption of the organisms’ lifestyle cases. The air, water, food, and waste management all form parts of the biological processes. Animals and plants need water, air, nutrients, light, and excretion to maintain their existence. 

Breathing clean air is necessary for humans. They need the air for metabolism that is essential for the buildup of energy. Where the air is polluted, or there is an outbreak of airborne disease, the public is exposed to infection. Dennis et al. (2016) indicate that the exogenous and the endogenous factors interaction with the biological processes determine the impact on the exposures. The quality of air human breathes different individuals differently, while unhealthy air quality affects everyone. The contamination that comes with the activities within the society affects the biological processes. Moreover, where one is affected by pathogens, they can quickly spread the pathogens to the next person through close breathing. Besides, some of the animals’ diseases are easily airborne, affecting humans and the public health directly, for example, the case with the swine flu.

The need for nutrients may lead to other effects that could be dire to the public. The foods taken by people differ considerably depending on the environment and the acceptable feeding habits within society. While eating is a necessary biological process, there are circumstances where the food taken exposes the public to some pathogens, for example, cholera. Besides, the inadequacy of some nutrients within the society may also lead to a more significant effect on the public (Baum, 2016). People need the balanced diet to prevent cases of chronic diseases such as goiter and marasmus. The functioning of the public will only be through the proper functioning of the brain. The functioning of the brain requires a properly balanced diet.

Water is essential for the body since a more significant percentage of the body is composed of water. Any effect on the water will grievously affect the public. The need for water for the biological processes may impact on public health. Water channels and distribution should be free from contamination to alleviate the public from health factors. While ordinary people hardly suffer from the water problems due to the treatment they do for the water, the homeless face serious factors as they use any water source, even the runway waters that contain many pathogens (Dennis et al., 2016).  The provision of pure, uncontaminated water should be sufficient in barring health cases.

The management of the wastes or excretions, which includes sewerages, poses a more significant threat to public health. Where the sewer lines are open and overflowing in public, there is a high rate of the cholera pathogens spreading within the community. There are cases of sewerage companies channeling the untreated wastes into the oceans and other water bodies. Moreover, the fecal or urinal excretion by humans increases the chance of spreading in pathogens to the community (Baum, 2016). Treatment of water and the control of deposits of human wastes into the public should be effective in reducing the disease spreading cases.
