causes of environmental problems,
the main cause of environmental problems is that there are 2 reasons
: 1. The increase of population (Population growth) of the population is increasing, it is still in the rate multiplier (Exponential Growth) when more people need. resource consumption is increasing every way, whether it is food, shelter, energy,
2. Economic growth and advances in technology (Economic Growth & Technological Progress) economic prosperity brought higher standards of living. According to Resources are consumed beyond the basic necessities of life. It is necessary to use more energy as well. Meanwhile, advances in technology, it enhances the way of resources easier and more
consequential arising from environmental problems. The
lack of natural resources Because it is not economical use of resources such as forests are destroyed. Lack of fertile soil Water
pollution (Pollution), such as pollution of water, air and noise pollution in the food, chemical, as a result of the intensive industry that
pollution
of our planet with a layer of atmosphere enveloped by a thick, about 15 kilometers floor. These consist of atmospheric nitrogen, oxygen, water vapor and dust. And Micro-organisms in these gases. Gas that is most important to the existence of. Life on Earth is a layer of gas and oxygen gas atmosphere with enough oxygen. To live with a thickness of 5-6 km. This usually consists of various gases is relatively stable nitrogen 78.09% 20.94% oxygen, carbon dioxide and inert gas. 0.97% for a fixed amount of gas above, we hold that the fresh air, but whenever a component of climate change to the amount of dust and gas smell smoke, vapor, steam, soot, and the radioactivity in the atmosphere was excellent. Too many of us call such conditions as "bad air" or "air pollution"
, the definition of air pollution,
air pollution, climate means that there are contaminants in higher than normal levels for the time. Long enough to cause harm to humans, animals, plants or other assets may occur naturally, such as dust storms. Volcanic eruptions, earthquakes, forest fires, natural gas, air pollution occurs. By nature is very little danger to humans. The origin is far and amounts to the condition. Environment of humans and animals is minimal. Cases caused by human activities, including pollution from the exhaust. Of industrial production from agricultural activities by evaporation. Some of the gas Caused by garbage and waste. As
a source of air pollution
sources of air pollution in Thailand is divided into two groups as follows
: 1. Vehicles
Vehicles cause air pollution in urban areas restricted to large jobs. But the problem of air pollution from industrial plants. The only problem areas scattered across the country, both in rural and urban
origin of vehicles
, rapid economic growth of the country's agricultural sector. The industry, making the center of Bangkok's business and population growth has increased dramatically. The demand for travel and transportation more. Cause traffic problems in a coma. Others are more severe and more. Traffic congestion causes cars moving at low speed. To stop and off frequently. The oil was burning up. The incomplete combustion of fuel. Ventilation and exhaust emissions in proportion to the increase. The area near the road, with traffic jams. There will be more severe air pollution problems. In areas where the traffic is flowing freely. Discharge of pollutants into the atmosphere caused. Transportation, including carbon monoxide Oxides of nitrogen gas Hydrocarbons Dust particles smaller than 10 microns, lead and sulfur dioxide 2. Sources of industrial pollution sources. Industrial generator Caused by burning fossil fuels and manufacturing processes. Which is a major cause. Impact on air quality and may result. Impact on the health of the community. Basically, or causing nuisance fuel used for industry, there are 3 major categories, namely fuel, solid fuel, liquid and fuel oil and diesel fuel at a gas such as natural gas and LPG air pollutants that. caused by burning fuels such as carbon monoxide, particulate matter, sulfur dioxide. And oxide of nitrogen It was found that the amount of venting to the atmosphere is increasing every year due to increased fuel consumption , emission from the sun at sunrise sun light from the sun to the health of body and mind more pleasant. As if it had been cleansed of dirt accumulated over the past day and night. We are so popular in the early morning sun, but the sun lines bolder. Body and mind will be calm, be gradually reduced to a smooth start to irritate the skin. The next time the sun will scorch the skin is brown, with white faces and peeling occurs. Allergic immune disease Fall sick easily, actually. Light from the sun is beneficial to both human beings, animals, vegetation science. And to the world at large as those in the tropics, often a disease of the bone. Since receiving enough sunlight to synthesize vitamin D3. It is useful to maintain bone. Or science, it can be ultra violet radiation from a synthetic chemical used in the analysis of solar lighting include various types of visible and invisible to the naked eye. Light or radiation hazards The ultraviolet This is what the eye does not see the type of radiation is electromagnetic radiation. With a wavelength shorter
