Environmental Issues

Public health is the science of promoting health, preventing diseases, and prolonging life by means of organized strategies as well as informed preferences of the public, private institutions, public organizations, individuals as well as communities. Public health aims at reducing the rate of deaths, premature deaths, as well as discomforts in the society. It helps people who are less fortunate to attain a lifestyle that is healthier. Interventions to change the lifestyles of people have been accepted as a way of altering disease patterns. The major aim of the public health is to improve the living standards of all people equally (Johnson, 2007).

Ways through which various countries deal with public health issues
All over the world today, governments as well as private organizations are taking the initiative of actively promoting the aims of public health research in order to give every person a fair chance to be a good citizen of the universe. Governments are also promoting public health research by establishing schools that mainly deal with environmental and health research. Health problems arise due to lack of knowledge on how to prevent as well as treat them. Many countries are putting more emphasis on public health research in order to increase knowledge and awareness about a certain disease and therefore generate ways of managing it. Public health research is therefore one of the major ways which various countries are utilizing to deal with health challenges facing them (Public Health Research, 2010).

One of the many public health issues that are facing many governments in the world today is the health insurance issue. Governments are encouraging private insurance in an attempt to solve three main problems facing the health care sector that is, insufficient access to care, increased costs, and a lack of improvement. Although the private sector may not solve all these problems, it will greatly improve the situation. Another way through which the international community intends to tackle public health issues is through educating health care professionals as well as the general public (Public Health Research, 2010). A person who intends to become public health personnel must have very high academic qualifications. Governments globally are also setting up public health programs in order to tackle particular heath care issues. A wide range of strategies are employed in these programs for the correct and timely approach to particular situations. These health programs are very beneficial to governments as they evaluate and find solutions to various problems easily. They have made a remarkable step in promoting health including the eradication of very fatal diseases in the world such as small pox. Another major world health concern is diabetes. This condition has affected millions of people in the world today. Various governments have set up programs that are aimed at educating the general public on the ways and benefits of eating healthy.

Environmental pollution is the other global health issue. Various countries have set up agencies that are responsible for combating environmental pollution. These departments develop rules and regulations that are aimed at reducing the rate of environmental pollution. Governments have also set environmental standards based on desirable objectives. Governments around the globe are encouraging people to use renewable sources of energy in replacement of fuel sources. In doing this, they intend to minimize the level of carbon dioxide emitted to the environment through combustion of fossil fuels. Various governments have also imposed heavy taxes on industries that produce large amounts of carbon dioxide to the environment (Herbert, 2001).
