The field of environmental health



Health environment is seen to question the health of the environment where the study of the impact of environmental changes on the biological and psychological human health in the short and long term; associated with the change in the atmosphere of gases ratios. If we know that the Earth air contains about 78% nitrogen in the atmosphere is converted to nitrate Bathadeh with oxygen under the influence of lightning, and fall with the rain makes the soil more fertile. Air earth also contains about 20% oxygen, and about 1% of Aragon, and the percentage of 0.013% of the carbon dioxide, very slim and proportions of other gases, and high water vapor and carbon dioxide ratios of carbon and methane and other gases causing the phenomenon of global warming.
The ozone layer function most UV absorption, but ultraviolet radiation high-energy taken to implement the Earth’s surface and become a threat to human health, animals and plants live and other microorganisms.
What implemented these rays have a positive effect on the human in terms of formation of vitamin D, but exposure to it for a long time leads to sagging skin burns and blindness, and the dates and cancer of the skin, and so on. X also affect UV in building materials, such as paints and materials for thermal insulation Kalpwlestaran and others, as UV rays affect the immune system in the human body and affect the plants and reduce the production of food in the sea, constitute a source of damage to plant and animal Balhoaúm which constitute essential food fish resources and to generate oxygen.
That which contributes to erosion and decay of the ozone layer are chlorofluorocarbons CFCs specifically, as these compounds contribute to the infrared absorption is done on the earth’s temperature to contribute to global warming, as well as contributing to the increase in carbon dioxide ratio of carbon and other gases into the atmosphere.

The field of aesthetic environment:
An area which looks at the environmental issue in terms of the vision of aesthetic nature in general and maintain them as Jamal source and tranquility and fun for everyone, and in terms of looking at the architectural styles of the facilities and harmony with nature and relevance to the needs of humans and the environment together, and in terms of the beauty of the historical, architectural and religious implications associated with the nature of the region and the cultural heritage and in terms of consistency and compatibility between these new elements and nature as a whole.
Any destruction of the aesthetic environment leads to negative effects on the human in terms of psychological trauma, conscious and unconscious, and in terms of the deterioration of air quality-related bugs, which affects the natural environment, and in terms of neurological health ailments associated with the demolition of building aesthetic nature which generates fun for everyone is in need desperately to not less important than the multiple pleasures collected from other sources necessary for survival, both physical (career) and mental (psychological).

Sustainable Development:
On sustainable development, to answer the question: What do we do in order to ensure preservation of the human race health and psychological condition is acceptable, but good for as long as possible?
In order to answer the last question we should take into account the environment if all their areas; as well as the management of natural resources and choose the most appropriate to achieve the above objectives, in addition to providing a minimum of comfort and well-being required to be human.
Conflicting expectations of scientists around the courtyard of the human race before the end of the third millennium, and requires them to get Optimists Advanced awareness of the dangers posed to us and avoid this disaster. What we need to do this as follows:
1. Sufficient scientific knowledge to observe phenomena and activation of Environmental Science and engage in philosophy.
2. The availability of a margin of freedom and democracy that allows the people to change its policies.
3. Moral attitudes of the global environment and a sense of belonging to one planet.
4. Consideration of the truth as relative to approaching people from each other and look at its history as the product of human years and looks forward to its future as a common destiny.
5. Launch a systematic awareness campaigns start of the child’s birth house, school is The university The workplace, and so does not break apart in a moment of moments.
Since 1987, the issuance of the United Nations Commission on Environment and Development report, began the concept of sustainable development takes dimensions include the conscious management of natural resources available to provide the needs of future generations and the rehabilitation of degraded environment and try to change the quality of economic growth and address poverty and meeting the basic human needs of the problems so as to achieve a balance between growth economic and environmental protection requirements to develop ways of production and the use of environmentally friendly technology. The strike, for example, to achieve sustainable development through the design of buildings, and also is to come:
Sustainable development relationship Sustainable Development Climate design and thermal insulation; is originally derived from the idea of thermal comfort within residential buildings and offices, which is also derived from the fact that the protection of the thermal insulation of the building from cracks and its contribution to saving energy and conserving natural resources.
So what is the thermal comfort in residential buildings, and how you can play the relationship between thermal comfort and sustainable development?
When a traditional building of Mussafah stone concrete or concrete bricks dumped or concrete father, a traditional construction methods in the Arab region, the degree of wall surface temperature from the inside, or the degree of surfaces knot surface temperature from the inside, be very high in the summer, at a time and you are very low in the winter, no less than 17 m and more than 25 degrees Celsius on the face of rounding, so if the average temperature of the indoor air temperature of about twenty degrees Celsius.
Based on the above, the use of thermal insulation in an appropriate manner in the walls of buildings and roofs exposed leads to the infinite degree of surface construction elements external heat from the inside between the two classes almost, so the human being comfortable inside his house in winter and summer, do not sweat the summer and shivering from cold weather winter.
