Effects
The effects of smoking will vary from person to person and depend on such things as:
a person’s susceptibility to chemicals in tobacco smoke;
the number of cigarettes smoked per day;
the age when the person began smoking; and
the number of years of smoking.
Immediate effects
Smoking one cigarette immediately raises a person’s blood pressure and heart rate and decreases the blood flow to body extremities such as the fingers and toes.
Brain and the nervous system activity is stimulated for a short time and then reduced.
A smoker may also experience dizziness, nausea, watery eyes and acid in the stomach.
Appetite, taste and smell are weakened.
Other effects of cigarette smoking
Smokers typically experience shortness of breath, persistent coughs, reduced fitness, yellow stains on fingers and teeth and decreased sense of taste and smell.
Smokers have more colds and flu than non-smokers and find it harder to recover from minor illnesses.
Smoking can cause impotence in men, while women who smoke are less fertile than non-smokers.
People who smoke tend to have facial wrinkles appearing much earlier and, in general, look older than non-smokers of the same age.
Smokers have an increased risk of developing:
respiratory infections such as pneumonia and chronic bronchitis;
emphysema (a progressive and potentially fatal lung disease);
heart attack and coronary disease;
cancer of the lung, throat, mouth, bladder, kidney, pancreas, cervix, stomach;
stomach ulcers; and
peripheral vascular disease due to decreased blood flow to the legs.
A person who is dependent on cigarettes may find that they experience withdrawal symptoms when they cut down or stop smoking cigarettes. These can include:
increased nervousness and tension;
agitation;
loss of concentration;
changes to sleep patterns;
headaches;
coughs; and
cravings.
Other dangers and important facts
Smoking during pregnancy can affect the unborn child, and babies are more likely to be born underweight, premature or stillborn.
Passive smoking, where a person is subject to breathing in the cigarette smoke of others, can cause lung damage, including cancer and heart disease.
Fifty Australians die every day from smoking compared with 10 who die from alcohol-related conditions or 4 who die from road accidents

Are non-renewable resources depletion in the world, and therefore resorted to the countries of the world to find solutions, such as the development of specific technologies able to use available resources efficiently, and reliance on renewable energy sources.
Are also subjected to the depletion of renewable resources, especially plant and animal, soil and XXXXls, it is caused by consumption of these sources at a rate higher than the rate of natural or artificial regeneration. One of the manifestations of attrition as follows:
Depletion of biodiversity and includes; depletion of vegetation cover, and the depletion of wild animals. Fastnzaf vegetation produced by over-cutting, overgrazing, and pollution, natural disasters, fires, volcanoes, drought, and the depletion of wild animals Vintage by overfishing, pollution and the elimination of wildlife habitat, and others.
To protect the biodiversity of attrition, I turned a lot of countries in the world to the establishment of protected areas for wildlife protection and animal and plant habitats, such as nature reserves, in Jordan there are six reserves administered by the Royal Society for the Protection of Nature RSCN, including reserves: Shaumari and Dana and Mujib, blue and others.

Waste of oxygen-consuming organisms, including pathogens and organic matter from food and plant waste and crop residues and waste water (domestic, industrial and agricultural). These materials are biodegradable, it can be oxidized in the water, so-called oxygen-consuming materials. Result in consumption of dissolved oxygen in water drained, and thus the death of aquatic strangled, such as fish and microorganisms, the air at the same time increase of micro-organisms anaerobic in the water which analyzes the organic materials anaerobically and produces toxic gases and odors resulting from NH3, H2S.
Organic and toxic substances, including oil, and juice in landfill sites. Water pollution affects the oil-water seas and oceans due to leakage of vessels laden with oil from oil wells or the sea. The juice Vtsab groundwater due to leakage from the landfill and dumps her candidacy through the rocks and then they reach groundwater.
Toxic substances, some of these non-organic material source rocks, as the liberated Baltjoah carry running water to lakes or rivers, or permeate the pores of the soil and rock contaminating groundwater. However, the human accelerated mining and processing operations in the liberation of toxic substances from the rocks at a rate thousands of times compared to natural processes.

Increasing pollution of water bodies steadily, raising questions about the vulnerability of fish by the pollution and dangerous eating human food of different fish, as well as to raise doubts about the true benefits of this important food source
The city of St. Louis is the annual conference of the American scientific research to support AAAS. In the context of the activities of this conference, a damage of environmental pollution on fish, an important topic for discussion. It is known that the meat of fish may contain Tlut by the seas and oceans on the toxic chemicals such as mercury, for example. If you feed the baby in the womb of the mother to a large amount of this XXXXl, it harms the nervous system and affects the fetus in the worst conditions Balichoh congenital disease and physical disability after birth. But it is also known that fish retain a very small amount of mercury in their bodies, but the monitor foodstuffs U.S. FDA years ago wanted to be cautious and advised pregnant women not to eat fish more than twice per week, in the interest of the health of the fetus.
[Edit] global warming
Points capture the temperature of the Alerdhalaanbas warming is the phenomenon of rising temperature in the environment as a result of a change in the flow of thermal energy and the environment. These are often called this name to the phenomenon of global warming than normal. And the causes of this phenomenon on the ground level of any reason for the phenomenon of global warming is divided scientists to say that this phenomenon is a natural phenomenon and that the Earth’s climate is witnessing a natural periods of hot and chilled cold citing this by the ice or cold somewhat between the 17 century and 18 of Europe. The solar radiation is the main source of energy on the surface of the earth, as it stems from the sun towards the earth is implemented through the gas atmosphere in the form of rays of visible short-wave, and X-ray thermal long-wave (infrared) and certain UV rays that can not be absorbed by ozone, Vimits surface Earth radiation hyphen to Faschen then, and the temperature is broadcast around the atmosphere in the form of near-surface temperature Faihtbs, not allowed to access or Alaavlat to the top, and re-broadcast to the ground, leading to increase the degree of the earth. Is beginning to feel the phenomenon of global warming since 1880, if the earth’s atmosphere warmed by half a degree Celsius over the past century, and will increase one degree Celsius by the year 2040 AD is expected to rise some 3.2 ° C up to the year 2100. Cause of carbon dioxide by about 72% of the global warming almost every year adds the world’s population is about 6 billion of this gas to the atmosphere. Came the term greenhouse of the similarity between what happens in Earth’s atmosphere and what is going on in the greenhouse (plastic) used in agriculture, as the sun beats long waves the walls of these houses Vchea heat in the atmosphere of procedure, where the plant, Fathbs Gerdanha ray thermal short waves and prevent them from dropping out, because they do not Tzmha air to escape from the temperature rises than others.

[Edit] Tsahraltsahr is subjected land degradation in arid and semi-arid and dry sub-humid, leading to the loss of plant life and biodiversity, and lead to the loss of topsoil and loss of the ability of land for agricultural production and support of animal life and human resources. Desertification affects the catastrophic impact on the economic situation of the country, as it leads to a loss of up to $ 40 billion annually in agricultural crops and increase their prices.
Each year the world loses about 691 square kilometers of agricultural land as a result of the process of desertification, while about one third of the globe vulnerable to desertification in general. The impact of desertification on the African continent in particular, where the desert stretches along the north of Africa, almost. It also became extending south as it approached the equator by 60 km than it was 50 years, and in more than 100 country in the world is affected by almost one billion of the total population of the world’s 6 billion people in the process of desertification of their lands; which force them to leave their farms and migrate to cities to earn a living.
Desertification is the phenomenon of geographical animated, acquired the environment in which the properties of desert real, as a result of the ecological balance of natural, with no deterioration, and a wide range in all environments, wetlands, and sub-humid, dry, semi dry, and under the double impact of the changed circumstances shifts natural plant, through the encroachment of the desert steppe region, the encroachment of the territory of steppes towards the territory of the savannah, the encroachment of the savannah region in the territory of the forest.
Is caused for the deterioration of ecological system, linked to piece the ability of resources, capacity, and if exceeded the exploitation of human resources capacity of, and have been exploited excessive and unregulated, the environment is exposed to deterioration, and becomes Mtssahrh Vtaatnaqs productivity of land, and unable production to meet the needs of human and animal food.
