Pollution is a major environmental health problem which affects both developed and developing countries. It may be defined as the contamination, or introduction into the environment, of substances and particles that are harmful or poisonous, thereby negatively affecting human health and the ecosystem. The first time I heard the word pollution, I was a child- I’m pretty sure the same is the case for every one because being a consequence of man’s existence, the history of pollution is as old as the human race itself and has persisted since time immemorial. Pollutants enter the environment through a number of natural and/or anthropogenic activities- consequently; increased combustion of fossil fuels in the last century is the reason for the present change in the atmospheric composition.

Different kinds of pollution include Air, Water, Soil, Thermal, Radioactive, Noise and Light pollution- the most common being Air and Water pollution. Frequent pollutants of air are carbon-monoxide, lead, nitrogen oxides, ozone, particulate matter, sulfur dioxide while water can be polluted by sewage, microorganisms, chemicals, suspended matter and oil spillage. Most people experience pollution-related symptoms such as watery eyes, coughing, wheezing and respiratory irritation, in the case of air pollution. However, the actual risk of health deterioration from pollution depends on an individual’s current health status, type and concentration of the pollutant, and the length of exposure to the pollutant. Individuals more susceptible to severe health problems from air pollution are those suffering heart and lung diseases, pregnant women, outdoor workers or athletes and children whose lungs are not fully developed.

In 2013, World Health Organization’s International Agency for Research on Cancer (IARC) assessed and concluded that outdoor air pollution is carcinogenic, particularly associated wih lung cancer. Other complications such as cardiovascular and respiratory diseases, stressed heart and lungs, damaged cells in the respiratory system, accelerated aging of the lungs, loss of lung capacity, decreased lung function and development of diseases such as asthma, bronchitis and emphysema have been attributed to exposure to air pollutants. The implicated air pollutants causing most health problems are small particulate matter of 10 microns or less in diameter (PM10) and ozone. An estimated 3 million premature deaths worldwide were attributed to outdoor air pollution alone in 2012. About 87% of these deaths occurred in low and middle income countries, which are disproportionately burdened by the health consequences of air pollution. Concurrently, water pollution results in disruption of food-chains, lead poisoning from eating contaminated sea foods and ill health or death of aquatic animals and lives that depend on the water bodies. It also causes diseases such as cholera, gastroenteritis and dysentery.

Some major air and water pollution disasters in history include Great Smog of London, Southeast Asian haze, Kuwaiti oil fires, Woburn-Massachusetts Water Contamination, Ghana Cyanide Spill, Elk River-West Virginia Chemical Spill, Walkerton-Canada Water Contamination Disaster and Zhuozhang River- Changzhi China Toxic chemicals leak.

Going forward, there are several measures to address pollution and preserve our health and that of our world. Examples include increased use of clean technologies that reduce industrial emissions, clean modes of power generation, cleaner heavy duty diesel vehicles and low-emissions vehicles and fuels and renewable combustion-free power sources (like solar, wind or hydropower), improved management of urban and agricultural waste, increased energy efficiency of buildings and compacting of cities, improved strategies for waste reduction- separation, recycling, reuse and anaerobic digestion to produce biogas. Additionally, we must do the little we can as individuals by being friendly to the environment!

The World Health Organization recognizes that the highest attainable standard of health is a fundamental human right. This includes access to timely, acceptable and affordable health care of suitable quality. Human right to health is influenced by health policies and programs which have the ability to either promote or violate them. Certain social criteria are also essential this right including the availability of health services, safe working conditions, adequate housing and nutritious foods. The right to health is similar to other human rights such as right to food, housing, work, education, non-discrimination, access to information, freedom, entitlements and participation. It constitutes the following:

1. Right to control one’s health and body (sexual and reproductive rights)
2. Right to be free from non-consensual or harmful medical treatment and experimentation
3. Right to a health system of accessibility, availability, equality, equity, universality and quality
4. Right to receive treatment or refuse treatment

Despite the fact that health is a basic human right… or should be, about 100 million people globally hit below the poverty line due to health care expenses yearly. Most vulnerable and marginalized groups within countries such as indigenous and minority groups bear a disproportionate amount of health problems, healthcare costs and limitations to accessing quality and affordable healthcare. This population experiences significantly higher mortality and morbidity rates than the general public. Some groups such as women, men who have sex with men and people who inject drugs also suffer poorer health outcomes due to social and economic disadvantage and discrimination. Moreover, the world’s most fatal communicable diseases – malaria, HIV/AIDS and tuberculosis – affect the world’s poorest countries, causing a burden on the economies of these countries.

Clearly, bigotry in the delivery of health services violates fundamental human rights and can have serious health consequences. Some examples include keeping people with mental health problems against their will, denying women access to sexual and reproductive health care and services, using people for experiments without informed consents or using them for harmful experiments, discharging unwell patients due to lack of hospital beds and forced procedures such as sterilization, abortions or virginity examinations in developing and developed countries. These violations create unequal health outcomes and can lead to ill health or death of the victims. Sometimes, it is often difficult to make fair decisions in the face of complicated and competing health priorities- however, researchers, health professionals and decision makers must be as fair as reasonably possible in policies and service delivery.

Reducing, and eventually closing the gaps in equality and access to health care and services require the effort of all individuals. More specifically, the responsibility of finding means to respect and protect human right to health is that of the health sector, government and international organizations that uphold human rights. In the last few years, there has been a growing acceptance for universal health coverage (UHC), a comprehensive means for strengthening health systems and improving health equity and access to health services. UHC has been identified as the third global health transition, following public health improvements like basic sanitation and epidemiological transition that decreased communicable diseases. International health and development organizations such as World Health Organization, World Bank, Rockefeller Foundation, Oxfam, Gates Foundation, International Labor Organization, and United Nations Children’s Fund support and promote UHC.

In the words of Dr. Margaret Chan, WHO’s director-general, “UHC is the single most powerful concept that public health has to offer and represents the ultimate expression of fairness.” Termed by many as a practical expression of the right to health, UHC was selected in September 2015 as one of the key targets to implement the health goal in the United Nations Sustainable Development Goals (SDGs). It is believed that through the continued worldwide adoption of UHC, the right to health will gradually be endorsed across all countries and social groups.

Access to comprehensive healthcare is fundamental to health and affects the overall physical, social, and mental health status. It is the ability of individuals or groups to obtain the services they seek, and is widely regarded as an important health determinant. Disparity in healthcare can be defined as differences or inequalities in accessing or receiving health care and services that help to achieve the best health outcomes. These differences and inequalities can be reflected in coverage, services, workforce, timeliness and quality of services received. Accessing healthcare requires 3 distinct steps which are: entry into the health care system, access to a health care location where needed services are provided and availability of health care provider with whom the patient can communicate and trust.

Research has shown inequalities in the distribution of health by race, income, education, neighborhood location, social class, gender and ethnicity. Health outcomes used to measure these include infant deaths and other preventable diseases and deaths, mortality rates, morbidity, disability, quality of life and life expectancy. Many individuals and families face barriers to health care and services including physical inaccessibility, socio-cultural issues or the cost of non-insured health services (e.g. eye and dental care, mental health services and prescription drugs). Other barriers include racism; language difficulties experienced by immigrants who cannot communicate in French or English; inadequacy of service providers available; lack of insurance; lack of cultural sensitivity, humility and understanding from health-care providers; location and the cost of transportation; extensive wait times; services not covered by benefits, a shortage of doctors/nurses in the area; low income and inability to create time from work and family responsibilities. To illustrate this, a study in Canada on immigrant women’s health showed that while immigrant women viewed health and prevention similarly to Canadian-born women, their ability to access the resources needed to stay healthy were different. At the same time, access to health care is also a challenge for Canadians in remote communities’ and Aboriginal populations who live off-reserve mostly due to location and the cost of transportation. Despite the fact that this population is more likely to report having unmet health care needs (20% compared to 13%), they are less likely than the overall population to regularly visit a physician.(77% compared to 70%). Barriers and challenges in accessing health care can lead to a deterioration of health, emotional distress and feelings of exclusion and isolation.

Few programs attempt to close the gaps in accessing health services by the undeserved population and reduce disparities in healthcare. They include West Prince TeleHomeCare, which provides another option for people deciding to live in their own homes while dealing with health issues and Toronto’s Mobile Health Unit which provides sexual health services onsite to the many immigrant women working in garment factories in Toronto’s downtown core.

The World Health Organization’s recommendation to address inequities and disparities in healthcare is that countries must address the systemic and structural stratification of their societies as a national priority. This means reducing the gap and inequalities in healthcare between those at the highest and lowest income levels through actions that will eradicate poverty and increase opportunities for employment, education and early child development among the entire population.

Social class is a function of socioeconomic status, a root cause and health determinant, which accounts for most of the health disparities seen in the world today. It is reflected in racial, gender and income differences between population groups both within and between countries. For example, the higher disease rates of African Americans in the United States when compared to Caucasians, have remained consistent despite many attempts to address them. This gap in morbidity among racial groups is widening in recent years for several causes of death. Specific minority populations have also shown higher rates for some health conditions just by being in their group, even when their social status is somewhat “equivalent” when compared to other groups. Factors that contribute to the differences in social status and negatively affect health by restricting socioeconomic opportunities include income, education, power, individual and institutional discrimination, gender, residence in poor neighborhoods, employment, bias in medical care, racism, and inferiority stigma. These factors, and their combinations constitute an individual’s social class.

Research has consistently proved that health is not only a function of genes and habits but is also influenced by class and status. The unequal distribution of power, money and resources also creates health inequities through a systematic and unequal distribution of opportunities to be healthy. Analyses of data from the German National Health Interview and Examination Survey  showed that in the last decade, the proportion of people belonging to lower social class has decreased while middle and upper social classes have increased. Some risk factors attributed to the differences in social class were smoking, obesity and inactivity, which were mostly associated with people belonging to lower social class. Concurrently, hypertension and hypercholesterolemia were more often observed in men of the upper social class compared to those belonging to lower class. Regarding morbidity, diseases such as  chronic bronchitis and gastric and duodenal ulcer were found to have higher prevalence in the lower social class while allergic rhinitis were observed more often in the higher class. Differences in social class are clear and many attributes are unique to people depending on which of the classes they belong. The contentment about life and health status was higher in the upper class while the level of complains and dissatisfaction about life and health status was higher in the lower class. Additionally, a study in Australia showed that the richest 20% of the population can expect to live an average of six years longer than the poorest 20%, just by belonging to then richer social class.

The British Epidemiologist, Michael Marmot, is a pioneer in this field of research. He studied English civil servants over some decades and found that irrespective of universal healthcare and race, people higher up the ladder (richer and upper status) lived longer and were less sick than those lower down (poorer and lower status)- even when behavior is accounted for. This effect or “social gradient” was consistent throughout the ladder as people just below the highest statuses tended to have shorter lives and be sicker than those just above them all the way down. Marmot discovered two variables that seemed to have a great impact on health and well being: a sense of autonomy or control over one’s life and work, and the ability to fully participate in the society. Naturally, people with higher incomes and education levels tend to have more control and power and contribute more to the society than those with fewer resources- a plausible explanation for the health differences. For example, a job loss may not really affect a rich educated man with multiple investments like Dr. K, but can trigger a disastrous chain of events including ill health for a low-wage worker.

Unity is simply defined as the state of being united or joined as one, usually towards achieving a common goal. It is a crucial feature for every venture in order to achieve set goals and objectives. Words like teamwork, group, affiliation, alliance, association, partnership, and collaboration buttress unity. Most times, nothing can succeed without unity because in its absence, disorientation and disorganization are not lacking. Be in it in our homes, schools, workplaces, churches, and the world at large, unity is essential to peace, progress and good health.

Given the relevance of unity, organizations such as United Nations (UN), World Health Organization (WHO), Economic Community of West African States (ECOWAS), International Monetary Fund (IMF), World Bank (WB), Universal Postal Union (UPU) and so much more exist. These organizations attempt to bring oneness and unity to our world today in various areas of life including social, health and economy. As huge and diverse as the world is, we are somehow connected through the internet, business, transportation… and this connection makes us vulnerable to one another by promoting the rapid transfer of health risks internationally. Many health issues are global in nature in that they transcend the boundaries and borders of countries… affecting continents and the world at large. In response to these global issues such as HIV/AIDS and other infectious diseases, climate change and health equality, solidarity is needed to help countries tackle health problems. Unity increases strength and empowers less developed countries through the assistance of more developed ones and large international donors.

The need for oneness and centralization in health provision is not new. The global community reached an agreement on the importance of providing holistic sexual and reproductive health services as far back as 1994. Increased unity is naturally beneficial because it increases coverage and access at lower cost as well as improves the quality of care and acceptance for stigma. Current priorities for Joint United Nations Programme on HIV/AIDS (UNAIDS) include sexual transmission of HIV, violence against women and girls, punitive laws and human rights and youth empowerment. These factors mostly affect developing countries and have spurred an increase in the number of global health initiatives (GHIs).

For almost two decades, the appearance of several disease-specific GHIs has modified the way international donors provide assistance for global health. WHO’s collaborative group on maximizing positive synergies reviewed and analyzed existing data, and 15 studies and described the complex nature of the interaction between country health systems and GHIs. Sometimes, the health systems and structures of individual countries do not align or integrate with GHIs, causing misunderstandings and frictions between countries and donors on the global scale. They concluded however, that if the necessary adjustments to the interactions between countries’ health systems and GHI are made by fostering unity, it will improve efficiency, equity, value for money, and outcomes in global public health. Hence, health systems and GHIs can complement each other and work together in order to mutually and positively strengthen global health.

Technology is the science of creating, applying and using devices, machines and techniques for productive purposes, processing actions and extracting materials. It is a widely used term which means different things to different people and has proven to be a never ending adventure for man. Technology has transformed from the mere manufacturing of automobiles needed to speed up transportation to the creation of diverse kinds of social networking platforms that aid man’s deep craving for a sense of belonging. When technology is applied or used in health, it is referred to as health technology. According to World Health Organization (WHO), health technology is defined as the application and use of organized knowledge and expertise for the creation and development of devices, medicines, vaccines, procedures and systems in order to solve health problems and improve the quality of life.

The relationship between health and technology is complex, and can be positive or negative. As suggestive of WHO’s definition, technology positively influences health and healthcare in various ways. For example; computers, electronic health records and other gadgets which are used in hospitals and for storing patients’ medical records greatly improve work and care efficiency as well as the safety, quick access to, and sharing of medical information. Secondly, the advent of sophisticated medical machines, devices, technology-assisted interventions and medicines facilitate the treatment of several health conditions and recovery of many patients. Additionally, the internet presents a platform where people easily access medical information and see health trends while mobile phone make communication between health care professionals and their patients’ faster.

Despite the much progress made in health through technology, human health has remained a victim of technology. According to an article by digital responsibility, excessive attachment to the tools of technology can result to psychological issues like distraction, narcissism, expectation of instant gratification, and even depression. The author explained how dependence on the seemingly harmless proceeds of technology can make an individual’s mind become a pool of imaginations, battle field and gross discontentment. This is very true because a survey which was recently carried out on young African students, showed that most of the students who had considerably comfortable lives became quite discontent about their lives and status after they had seen the sheer display of flamboyance in the lives of fellow students. Furthermore, a study from the University of Illinois found an association between technology addiction and anxiety or depression in college-age students.⁵ This association was not present in students who used technology less frequently.

Regrettably, technology also affects our physical health negatively through exposure to electromagnetic waves from mobile phones, x-rays from scans, excessive light from television and device screens, loud noises from turbines, vibrations from subway trains,  chemicals from battery, oil spillage from refineries, emissions from nuclear weapons and through the inhalation of polluted air released into the environment by automobiles. There is also an increased risk of chronic diseases such as obesity due to the sedentary lifestyles and reduced physical activity associated with technology.

In conclusion, technology is a beautiful aspect of life which is not intended to deteriorate health, yet it almost always does. Therefore, we owe it to ourselves to take control of our lives- choices and actions so as to ensure that the very tools meant to help us are not unfortunately harming us.

Edutainment is defined as the means and method of educating, teaching or impacting knowledge through various forms of entertainment. Many scholars agree that edutainment originated in Latin America where it was mostly used in Tele dramas. The term is fairly new to a lot of people; however, we experience its influence when we watch and learn from movies, documentaries and shows. Edutainment is an effective teaching strategy used to describe the acquisition of knowledge through a medium which individuals can connect to as fun or exciting. The major aim of edutainment is to catch and keep the attention and interest of participants while passing relevant life changing knowledge and lessons that have the potential to inspire behavior change and improve health.

There are many different forms of Edutainment. Programs that are “edutaining” include television (TV.) productions, movies, museum exhibits, games and computer software; the most common being the use of games and technology to educate children. As we know, it’s a tough job to get and keep the attention of many children; therefore, edutainment provides a means of strategically and effectively holding their interest while teaching. Additionally, edutainment has been successfully used in the adult population to address some health and social issues including obesity, poverty, substance abuse, immunization, teenage pregnancy, HIV/AIDS and cancer. Reputable universities in the United States such as, Johns Hopkins University and the University of Wisconsin-Madison have also used edutainment initiatives. Furthermore, Non-governmental organizations (NGOs) and government agencies such as Population Communications International (PCI) Media Impact and U.S. Centers for Disease Control (CDC) respectively have created and used materials with edutainment content effectively.

Edutainment has been used in different countries and its benefits are convincing. Examples include East Los High, a trans-media program targeted towards young Latin Americans. Since studies have shown that this population has a high risk of sexually transmitted infections and adolescent pregnancies, the program promoted sexual and reproductive health using educational messages in entertainment narratives across digital platforms. At the end of the program, findings from online analytics tracking, viewer surveys and laboratory experiments showed that it had a positive emotional and social impact on sexual and reproductive health in the population. Another study in Belgium proved that students who watched edutainment series of TV cooking shows and dramas significantly demonstrated more knowledge about fruit and vegetable recommendations compared to a control group.

Despite the many benefits of using edutainment, some people argue that some activities emphasize entertainment much more than education, hence, undermining the importance of education. Also, learning is a cognitive process which requires attention by concentration and active thoughts rather than entertainment. That said, it is important to understand and use the appropriate combination of education and entertainment in any edutainment program in order to achieve effective results. Moreover, changing a behavior requires more than just the knowledge acquired through edutainment; therefore, efforts should be made to concurrently address the social and structural factors that hinder behavior change.

Education is a social determinant of health because whether or not we are educated and the level of our education can affect our health. In the same way, our health can influence our level of education because healthy children and individuals are more likely to remain in school and complete their education compared to the unhealthy ones.

There are many ways by which education can influence health; First and foremost, going to school increases our chances of getting better paying jobs and higher incomes and as a result, we can easily afford our health needs. In addition, education is empowering in itself since educated individuals are more likely to take control of their health, promote and sustain healthy lifestyles and positive choices, proactively seek options for healthier lives and support or nurture their personal development, human relationships and personal, family and community well-being.

As stated by World Bank, Health and education form the basis for human development and without either, it becomes increasingly difficult to survive. Without health and the relevant skills and knowledge acquired through education, one cannot hold a job or care for a family. Therefore, increasing access and reducing associated costs to health and education services is an important factor for any strategy in order to eliminate poverty and reduce inequalities.

The World Health Organisation (WHO) reported that road injury is one of the ten leading causes of death worldwide, killing about 1.3 million people in 2012. Road accidents occur in every country but much more in developing countries due to bad roads.
Globally, Nigeria has the second highest rate of road accidents among 193 countries of the world. In 2012, at least 473 people died from a total of about 1,115 road accidents nationwide. These accidents have become a constant daily re-occurring phenomenon, rather than an emergency that requires immediate response to rescue possible casualties. The toll that traffic accidents exact in Nigeria has attracted global concern, as Nigerian roads have been adjudged the most dangerous in Africa by W.H.O. According to the report titled “Road Safety in the WHO African Region”, more than one in four traffic accident deaths in Africa occur on Nigerian roads.
The need for a reliable and fast response team cannot be overemphasized as many lost lives could have been saved, if there was a response to the accident that claimed their lives. It’s really unfortunate that a Nigerian who finds him or herself in an emergency situation would not have access to an emergency response team. Countless Nigerians have also watched their loved ones cry to death due to delay in the arrival of rescue teams. Although road accidents are a part of life and can happen at any time, the resulting effects can be controlled and mitigated so as to have no or minimal number of casualties.
The recommended option to increase road safety and reduce road traffic accidents in Nigeria is to first, improve the quality of the roads and effect the use of traffic lights and road signs. Then, assemble have a reliable stand-by emergency response team, with an active phone number to call, in case of road accidents.
