I shall indicate Ireland to explain whether environmental factor is the main factor to influence our quality of life and economic growth. Is environmental quality higher in the Ireland west regions? And if so, does this compensate for lower incomes in these regions? Is it bad that rural areas are characterized by higher costs of living in areas other than housing by environmental factor? In fact, in Ireland, UK country, population increase has a direct impact on the environment by placing demands on local natural resources, particularly open space and water. It also leads to a sense of crowding that reduces the utility associated with access to the environment. How can environment factor influence economy growth in Ireland? In Ireland, agriculture has gone through a period of significant change that has been accelerated reductions in the amount of mixed cropping and traditional land management. Indeed, changes in the expectations of young farmers will ensure that further change is likely to be characterized by increases in farm size and greater specialization with implications for landscape and wildlife. These characteristics of farm holdings are more familiar in the east regions of Ireland, UK country. As with likely to extend to the west regions as the older generation of farmers retires, although this will probably be accompanied by a trend to more farming of production needs to young farmers. So, good natural environment can provide Ireland young farmers to produce more agriculture to earn income, even who can export more rice, fruits, vegetable etc. agriculture foods to overseas. Hence, Ireland GDP will be raise if it can have good natural resource environment to provide Ireland young farmers to grow foods to sell to domestic and /or foreign agricultural market. Given the rate of economic growth, and its concentration in the east of the Ireland, UK country, it would be easy to presume that the quality of the environment is higher the further away from the mid east one goes. Thus, good natural environment is an important factor to influence the farming industry development in Ireland, UK county to satisfy their needs and to raise their quality of life nowadays.I shall indicate New Zealand and America two developed countries to explain why which are facing environmental pollution challenge to influence their citizen's quality of life and economic growth nowadays. The first country is NZ, although, New Zealand is a developed and natural environmental country, but it had been envountering air pollution annouance and noise annoyance to influence it's citizen's health-related quality of life. I shall indicate why which has this relationship between of them in New Zealand. Nowadays, New zealand population growth is an increasing demand for consumer products and urbanization have lead to concerns over the lived environments in many of the world's cities, such as Auckland, wellington cities in New Zealand. However, environmental quality is an important determinant of health, such as the bad influence of traffic-related air and noise pollution on health outcomes, specially with respect to at risk groups, both in relation to long term exposure as well as acute effect, from brief exposures. For example, cholesterol levels and in relation to myocardial infaction. Nowadays, New Zealand is encountering the high degree of air pollution and noise annoyance to influence it's citizen's quality of life. Air pollutants can be detected either visually, such as witnessing smoke emanating from a vehicles's exhaust, or by smell, such as when odorants stimulate olfactory receptors. The evidence linking air pollution to adverse impacts on human health.
