Tehran's geography makes air pollution worse: the Alborz Mountains at its north side trap the increasing volume of pollutants and lead these to remain and hover over Tehran when the wind is not strong enough to blow them away. Furthermore, Tehran's high altitude makes fuel combustion inefficient and adds to the problem. Its altitude is between 3, 300 and 5,000 feet and it is in this space that the pollutants are trapped since the destruction of orchards and other vegetation especially in northern Tehran in the past decades by rapid development and human activity pressures. These natural and man-made factors together have made Tehran one of the most polluted cities in the world. Air pollution reached critical level in December 1999 when high levels of carbon monoxide and other pollutants filled Tehran for many weeks. Deaths, diseases and skin conditions are attributed to extreme air pollution. Records say that more than 4,000 to 5,000 die because of it every year (EIA).
Increasing population also meant increasing use of energy and this is the case in Iran, particularly its capital Tehran (Energy Information Administration 2002). Its total energy consumption rose from 1.6 quadrillion Btu in 1989 to 4.7 in 2000 or three times, mostly as gasoline. Its 2 million car drivers alone use 7 million liters of gasoline every day. Oil is abundant in Iran, petroleum products are subsidized and, thus, cheap cost prevents oil producers from turning out more fuel-efficient products. In May 2002, the government's subsidy was several billion dollars a year. Natural gas was roughly 50% of the energy Iran consumes. It uses up 73.8 million Btu, only a fifth of what the U.S. uses at 351.1 million Btu, and the figure continues to go up (EIA).
Poisonous carbon emissions in Iran have steadily increased in the last two decades by 240% since 1980 or from 33.1 million metric tons in 1980 to 80.8 million metric tons in 2000 (Energy Information Administration 2002). The uncontrollable growth of the population has clearly meant an increased and constantly increasing number of cars. The volume of automobile exhaust in Iran alone constitutes 1.3% of the world's total of carbon emissions. While Iran's carbon emissions are lower compared with those in the United States and other industrialized or developed countries, its rampant use of leaded gasoline and the volume of cars without catalytic converters account for the massive levels of carbon monoxide in Iran's urban areas. These poisons are predicted to continue spreading until the roots of the problem are genuinely and adequately addressed (EIA).
On top of all these, Iran's renewable energy consumption is and remains low (Energy Information Administration 2002) precisely because of its abundant oil reserves, which account for 9% of the world's reserves and 15% of...
There are also influential political interests in various industries who are lobbying Congress to promote data that indicates climate change is not related to human activity. The lab experiments support the human origins of global warming through comparing average temperatures and fuel emissions over the course of the industrial era and beforehand. Materials and Methods: The methodology of the study was to examine the standard deviation of temperatures spanning from 1860 (the
These restoration efforts affect natural wetlands that have been destroyed by mankind and then proposed to become urbanized. Conclusion Although the impact on the climate by humans has had several negative impacts, such impacts have the potential to be stopped and even reversed. Research clearly indicates that recent technological advances can be used in these cases as a valuable tool in determining whether natural processes can be restored, or whether other
According to the Oregon Environmental Council the estimated cost per year of environmentally attributed cancer is around $131 million for both adults and children. Much about cremation is unknown but it is believed that the process of cremation emits several harmful chemicals into the air including benzene, mercury (from mercury fillings) and persistent organic pollutants. Modern crematoriums, like any burning industry are regulated by laws and standards that require
In many situations, and the one described in "Coup de Torchon" is an eloquent example, native societies do not exist. If we have a look at the solitary native society, as described in Daniel Mengara's book "Mema," and then turn to the situation described in "Coup de Torchon," we have a relevant experience of what it means to place together two entirely different social structures. This is perhaps one of
Human Effects on Coral Reefs Coral reefs are one of the oldest ecosystems in the world, existing for more than 450 million years. A coral reef is a type of biotic reef that develops in tropical waters. Coral reefs are found in all oceans of the world, generally between the Tropic of Cancer and the Tropic of Capricorn because the reef-building corals are living in this waters. A water temperature of 20
