Environment Economic Methods

Why social and physical environmental factors have close relationship to influence economic growthI shall indicate reasons to explain why social and physical environmental factors have close relationship to influence economic growth, even human health of quality of life. The social and economic burdens of poor education, lack of affordable housing and less than self sufficient income affect, not just those individuals and families who have the fewest resources. The social gradient means that not only do whose in the bottom worse health outcomes to bottom of income group and the top income group whose will have poor quality of life influence. The higher rates of disease and disability and lesser productivity among many communities means a higher public and private burden of life years, particularly life expectancy once one reaches age 65. In recent decades, research and has increasingly shown how powerfully social and economic conditions determine population health and differences in health among subgroups, much more so than medical care. It seems that environmental factor can influence human's quality of life.Los Angeles Country Department Of public Health (2016) indicated a country health rankings model, this department explained these three health factors can cause this health outcomes. These health factors include health behaviors (30%), it includes tobacco use, diet and exercise, alcohol use, unsafe sex; clinical care (20%), it includes access to care, quality of care; social and economic factors (40%), it includes education, employment, income, family and social support, community safety; physical environmental factor (10%), includes natural environmental quality, built environmental quality. Then these factors can cause this health outcomes, such as morality ( length of life):50% and morbidity (quality of life):50%. SO, it implies that physical environmental factor can influence human's length of life. So, on our social environmental problems result is from a complex interplay of a number of forces. An individual's health -related behaviors, particularly diet, exercise and smoking, surrounding physical environment and health care ( both access and quality) all contribute significantly to how long and how well human love. However, none of these factors is as important to population health as are the social and economic environments in which human live, learn, work and play. We refer to these factors can be as the social determinants of health to influence our quality of life. How do social determinants affect our quality of life? In the late 19th and early 20th centuries, public health concentrated particularly on the physical environment. Improvements in, for example, clean water supplies, healthier housing, sanitation, workplace safety and safe food lead to sharp increases in average life expectancy . Also our quality of life needed to be concentrated on expanded access to medical care, resulting in further expansion. So, the poverty tap is now characterized by those elements, such as low levels of: (i) environmental quality, (ii) life expectancy and (iii) human capital.In fact, environmental degradation can have a significant impact on human health. De Hollander et. al (1999) & Melse & De Hollander (2001) showed that estimates of the share of environment, related human health loss are as high 5% for high income countries, 8% for middle income countries and 13% for low income countries. Air pollution and exposure to hazardous chemicals are important causes of the related burden of disease in countries. The transport and energy sectors are major contributors to air pollution, when important sources of chemical pollution are agriculture industry and waste disposal.
