Effects of Environmental Impacts on the World’s Population

Over the past five decades, human-related activities have been central in increasing greenhouse gas emissions and carbon dioxide, resulting in additional heat in areas where the atmosphere is relatively low. According to research, the world has become increasingly warmer in the last century by at least 0.85C. As a result, the sea levels have been rising, coupled with melting and changes in glaciers and precipitation patterns (Tong & Ebi, 2019). The environment is rapidly headed to a non-habitable state as more intense and frequent weather patterns emerge. In terms of the environment’s health, it is increasingly becoming negative as the changes impact various significant determinants of health. Environmental and sociological determinants of health such as clean air, available and safe drinking water, shelter, and adequate food are largely being impacted by environmental changes (Patz & Olson, 2006). This section will evaluate how the environmental impacts have influenced people’s health globally and provide interventions to improve the impacts and reinstate a healthy world.

Areas that feature high temperatures result in deaths of people from various hearts conditions and respiratory diseases, especially the eldest. Extreme heat is associated with raised ozone levels and incorporating other pollutants in the atmosphere that raises the chances of cardiovascular and respiratory issues. Every year, natural disasters are being recorded at an alarming rate as more people die, especially in third world countries, as a result of drought brought by varying rainfall patterns. The increasing temperatures and weather lead to home destruction as well as medical facilities where people receive healthcare services. In addition, inadequate drinking water as a result of drought interferes with people’s hygiene and exacerbates the chances of diarrheal diseases, which are one of the killer diseases in children aged below five years.

Environmental conditions strongly impact water-borne diseases and diseases primarily transmitted via snails, insects, and other plethora of animals. Environmental changes increase the transmission levels of significant vector-borne diseases and, in the process, alter the geographical range. According to research, environmental changes are projected to increase the occurrence of snail-borne infection schistosomiasis over a wide area. Malaria, a disease transmitted by the female anopheles mosquito, eliminates close to four hundred thousand people annually worldwide (Martínez-Santos, 2017). This highlights the environmental impacts on the overall health of the people around the globe, as slight changes and varying patterns that are being witnessed are increasingly posing significant threats.

There are a plethora of different chemicals that can impact the health of a human being distinct. Such chemicals are known to expose human beings to dangerous substances that exacerbate their vulnerabilities. Achieving chemical safety is realized by reducing the impacts of natural and synthetic chemicals. Based on the World Health Organization statistics, in 2016, more than one million deaths resulted from the presence of few chemicals in public (Mikhaylov et al., 2020). The chemicals are taken via contaminated water and pesticides that are applied in various food consumed by people.

Environmental factors can inhibit a group of people from accessing healthcare services in a given location. This results in the prevalence of diseases and, consequently, poor health outcomes in the group as a result of the inability to access health care services (Tong & Ebi, 2019). According to research, a lot of people face various bottlenecks that limit their ability to access the services factors that result in lack of access include economic instability in a place, poor infrastructure to hospital facilities, and minimal education concerning the significance of hospital centers and their role in disease handling (Martínez-Santos, 2017). Such people are vulnerable to chronic conditions, and their health can deteriorate within a short period due to a lack of adequate healthcare services. Infrastructure, for instance, incorporates poor access roads, inadequate access to safe drinking water, and healthcare infrastructure.

To minimize the impacts of the environment on people’s health, healthcare systems and practitioners should focus on ensuring a better environment that aids their delivery process. This is achieved through enhancing the environmental performance of every sector involved in the production of greenhouse gases to minimize the lethal effects that can be attributed to its environmental impacts (Tong & Ebi, 2019). Everyone health is at risk based on environmental impacts they are exposed to, although some are more vulnerable. For example, people stationed in coastal areas, developing states and countries, and mountainous regions face significant threats to their health and safety. Also, children in third-world countries are vulnerable to health risks that lead to future health outcomes. Furthermore, areas that face poor infrastructure in facilitating healthcare access by the public, especially in developing economies, are least equipped to ensure adequate and consistent provision of healthcare services to people (Mikhaylov et al., 2020).

Another significant intervention is to elevate the proportion of people who have access to an adequate and safe drinking water system that meets the regulations set by the World Health Organization. The standards ensure the water available to the people meets safety standards, mitigating prevalent diseases due to drinking contaminated water. Also, ensuring the toxic pollutants released to the surroundings are minimized ensures the availability of healthy air that minimizes and controls environmental conditions (Tong & Ebi, 2019). Ultimately, ensuring that people who do not have sufficient education concerning the significance of the healthcare system receive an education that informs them of the significance of seeking medical care for their health and wellness.

In conclusion, environmental impacts have affected the world population in a plethora of ways. The prevalent pollutants in the environment have prompted natural disasters such as drought that lead to massive deaths, especially in developing countries. The changing climatic patterns have resulted in inadequate drinking water, and the little available is often contaminated with chemicals that increase health risks. Underdevelopment and lack of education exacerbate health risks as people lack the know-how on ways to ensure they are health secure, requiring the governments to invest heavily in programs aimed at sensitizing people on the significance of their health and seeking healthcare services.
