How Environmental Changes Affects Public Health Professionals


In recent times, human influence on the environment has reached a global scale, which is reflected on the rapid increase in land use, population increase, energy use, and advancement in technology. These influences have increased awareness that long-term health of the population highly depends on the persistent stability and functioning of the ecological systems. Various environmental changes have posed great challenges to the public health professionals (McMichael et al., 1998).

Air Quality

Scientific studies show that pollution levels in various states exceed WHO standards due to increased use of aerosols sprays, dusts from mines, emission of harmful gases such as carbon monoxide, lead pollution, Sulphur dioxide, and nitrogen dioxide from industries and automotive (McMichael et al., 1998). Increased air pollution has caused the emergence and re-emergence of airborne diseases such as influenza virus and Middle East respiratory syndrome coronavirus. This has also caused persistent of various diseases such as tuberculosis and increased the number of people with asthma in a population. Infections such as tuberculosis have persistently shown an increased rate of drug resistance (Hassan, Hashim, Z., & Hashim, 2016). The increased rate of infection, rapid emergence and re-emergence of airborne infections and continued resistance of diseases to medication has increased on the cost of treatment and cost of research thus increasing the public health budget.

Water Quality

Changes in various hydrological aspects have explicit effects on public health professionals. Damning effects of various rivers has increased the prevalence of lymphatic filariasis and malaria primarily due to increased breeding sites. Flooding and overloading water bodies with waste has increased the rate of infection with cholera and typhoid. This would largely affect the public health professionals with increased mortality and morbidity rate, increased cost prevention, and treatment (Hassan, Hashim, Z., & Hashim, J, 2016). Water bodies’ pollution has continuously degraded water ecosystems, which has led to a decline in the availability of seafood proteins which is important in public health. Access to certain important proteins such as Omega III oils has gradually reduced, thus degrading the immune system and brain development causing increased cases of body and mental retardants in the future.

Climatic Changes

Changes in weather patterns have continually increased the rate of mutations to vectors of diseases, especially insect-borne diseases such as malaria. Global warming has execrated the prevalence of malaria not only in coastal regions, but also tropical areas due to mutation and favorable conditions for the vector caused by globalization. This continuously affects health professions as the need to research for new medication and control measures is inherent (Patz et al., 2000).

Over time, human activities have gradually induced drought, which has caused reduced access to balanced diet due to low production of agricultural land. The lack of a balanced diet will affect professionals in the public health such that the occurrences of nutritional-related disorders will increase. The lack of an adequate and balanced diet suppresses the immune system, thus the body lacks the ability to fight diseases which cause a high rate of infections with diseases causing microorganisms in the specific population (McMichael et al., 1998).

In conclusion, human beings have coined their existence with the prevailing environmental conditions. Consequently, changes in environmental conditions have equal or greater effects to the public health of a population. This has led to the emergence of new diseases, re-emergence of diseases previously eradicated, drug resistance, and vector mutations and disease causing microorganism mutations. This will lead to increased prevalence of diseases and increased mortality and morbidity rate. Thus, for a population to have a sustainable and healthy life span, the public health professionals have a duty to join other sectors in coming up with ways of sustainably protecting the environment from degradation (Hassan, Hashim, Z., & Hashim, J. 2016).
