Environmental Impact Upon Health Essay Example for Free
environmental Impact Upon Health EssayWe merciful race have captured the environment to make our lives beautiful but through with(predicate) our activities and materialistic pursuits, we have made environment the biggest enemy of our health. We have ourself created an environment which has given us each(prenominal) leisures of life but on the other hand we have dug the walls of un reasoning(a) livings also in it. In 1997, Department of Health Canada passed a report which stated The reinforced environment is part of the boilersuit ecosystem of our earth. It encompasses all of the buildings, spaces and products that argon created, or at least signifi stinkpottly modified, by people. It includes our homes, schools and workplaces, parks, business aras and roads. It extends overhead in the form of electric transmission lines, underground in the form of waste disposal sites and subway trains and crosswise the country in the form of highways. (Hancock, 2000) In the contemporary so ciety of today, built environment is the most critical aspect of our lives. All over the world, more than 85 per cent of people are living in urban dewllings and 80 per cent of Europe and North the States have urban population.These urban settlements are creating an adverse impact on the vivid environment. They are using maximum amount of the worlds resources and in return are producing maximum waste from them. Even leRiche and Milner (1971) explained in Epidemiology as Medical Ecology, unity of the most striking changes in the ecology of man has been the growth of cities. (Hancock, 2000)The WHO Expert Committee on environmental Health in Urban Development (WHO, 1991) pointed that In some respects, urbanization can itself be considered to be a key variable in the health equation when the pollution produced by a thickly packed population outstrips the natural absorptive capacity of the citys ecosystem, adverse health effects can be increased where controls are lacking or unrelia ble. (Hancock, 2000) Urban civilization can non be termed as a natural ecosystem as it is completely built by humans encompassing almost whole globe in its vicinity and destroying the very concept of being Natural.It is a complex human ecosystem which constitutes both material environment created by humans and the social, economic, ethnical and political environments in which the humans survive. In North America itself, human beings spend around 90 percent of their time inside the four confines of their doors, some other 5 per cent in their cars and remaining just 5 per cent outside. And outside too, they are pass maximum time in the vicinity of the built urban environment.It is a general trend of humans to consider the poor diet or just lack of exercise as an excuse for their harmful health but they hardly consider the ill effect of the built environment with the housing characteristics, patterns in land use, transportation etc. It is evidently proved without doubt that when t hese different modes of our living standards are not created keeping the ecological balance into consideration, the ecosystem collapses (Jackson Kochtitzky, Online Edition) which deteriorates our health causing stress, chronic diseases etc.The haphazard urban education leads to the climate and atmospheric changes, pollution and ecotoxicity, resource depletion and reduced habitat and bio- diversity. (Hancock and Davies, 1997) The subject that encompasses the link between these human endeavors and the public health is kn aver as human ecology. This human ecology can provide integrative, holistic and radical perspective on health issues. (Hancock, 2000)Catalano in 1979 propounded that there is an utmost need that the health issues moldiness take into consideration economic and social processes which shapes community, so as to prevent any spread of diseases. Hancock, 2000) The metapopulation guess gives an enduring account of urban ecosystems and the human aspect of the study of the urban systems can be through with(p) by the human ecosystem model, which deals with the social components which are the part of the human system and its connections to ecology. (Niemela, 1999)The Mandala of Health is a model, which establishes the human relationship between the natural sciences and the social sciences and gives suggestion at every level of human activity jibe to its environment. Hancock Perkins, 1985) Another model, which has incorporated the most important characteristic of ecosystem, is a Butterfly Model of Health. In this model, health is related to societal, economical goals and patterns and biological resources for self-renewal. This model states that morsel of bio natural and socioeconomic holarchic environments represented by wings, which keep up an influence on the health of any individual or whole population. There are number of biological and behavioral filters that engulf the human beings.The nature, people and these factors affect each other. Peopl e are considered as hefty when the two wings of the butterfly are in equitable balance within their own dimenisons. In other words, when the biological and other factors maintain equilibrium in nature, it will lead to the healthy individuals. (VanLeeuwen, Toews, Abernathy Smit, 1999) Overall we can say that the health of the human beings is dependent on the health of the natural ecosystems and the planet. accordingly it is utmost necessary to keep the urban ecosystems healthy keeping in mind both its physical and social dimensions such as health of the population with regard to the mental salutary being, the social well being of the urban community with regard to their social and cultural aspects, the quality of different components that make the built environment, the quality of the environment in the vicinity of the urban sphere like clean air, clean water, soil, cake of noise pollution and the urban ecosystem on the overall ecosystem of planet.Indicators of Population Health at the Community aim formulated a model known as the Healthy Community model. (Hancock, 2000) This model reflects on the environmental, social, economic, cultural and political factors that lead to the health of urban populations. There are three main parts, which make up the healthy community model. These are community, environment and economy, which in turn possess three qualities like livability, viability and sustainability.These qualities are related to our living styles and we humans have to make the outdo use of the available resources to maintain these qualities for our healthy lives. For e. g. Traffic causes respiratory problems because it causes air pollution and noise pollution. This healthy community model provides answer to the best way possible to control traffic. The theories and models show how we can maintain and improve human and ecosystem health, which will study changes in the way the urban settlements are planned, designed and worked upon.Canadian Public Heal th Association Taskforce on Human and Ecosystem Health in 1992 said in a report Human development and the proceeding of human potential requires a form of economic activity that is environmentally and socially sustainable in this and future generations. (Hancock, 2000) We cannot change the urban settlements but we can sort out ways by which we can reduce the pollution, and make our environment the most beautiful and healthy place to live in.
