  • But we are only now learning how to look after water. Acid rain has polluted as many as 18.000 lakes and our seas. And rivers are polluted with waste products. It is now very expensive to try to repair the damage which has been done. We have some hope for the future, though, because new sources of water have been discovered

  • As resources become scarce, they become more valuable. Value is evidenced both by the increasing prices of resources and by controversy over resource allocation and management. From forest harvesting and land use conversion throughout North America, to the fragmentation of tropical bird habitat, to acid rain deposition in Eastern Europe, to Siberian tiger habitat loss in Russia, people have significantly affected the ecosystems of the world. Expanding population pressures continue to cause the price of resources to increase and to intensify conflicts over resource allocation....

  • The problems associated with the frenetic combustion of fossil fuels are many: pollution, global warming, and foreseeable exhaustion of resources, among others. Although difficult to estimate, the costs associated with these problems are huge and indirect,8 and may be financial, human, or both. Costs induced by pollution include, but are not limited to, health expenses, the cost of replanting forests devastated by acid rain, and the cost of cleaning and fixing monuments corroded by acid rain. Health expenses probably represent the largest share of these costs, especially in developed...

  • It is estimated that NRs. 0.5 billion per year in tourism revenue is lost due to air pollution in Kathmandu valley (World Bank, 1997). Findings of a survey conducted among 1,702 tourists between May and June 2001 by MARG Nepal indicate that the quality of air is the number one area where tourists feel improvement is needed. This shows that Kathmandu’s poor transportation system and pollution is not only affecting human health and environmental quality, but also the tourism industry (Business Age, 2001).

  • Comparing the total air pollution related health costs per capita (see Figure 14) the results of the three countries stay within the same range, although the central estimates indicate differences between the three countries. The highest per capita costs are shown for Austria. For the road traffic-related health costs, the per capita results differ much less between the three countries: The highest value is obtained in France with about 370 EUR per capita, followed by Austria with about 360 EUR per capita and Switzerland with about 310 EUR per capita.

  • A heightened concern for the environment, combined with increasing sophistication in tracking and modelling air currents, has led to the realization that local air and water may be contaminated by pollutants emitted many miles away. Indeed, this realization has resulted in inter-regional and international tensions regarding air pollution. For example, much of the acid rain problem in the northeastern United States is a result of SOx emissions from coal-fired power plants in the Midwest.

  • China is rapidly developing as evidenced by enhanced urbanization and industrialization and greatly increased energy consumption. However, these have brought Chinese cities a variety of urban air pollution problems in recent decades. During the 1970s, black smoke from stacks became the characteristic of Chinese industrial cities; in the 1980s, many southern cities began to suffer serious acid rain pollution; and recently, the air quality in large cities has deteriorated due to nitrous oxides (NOx), carbon monoxide (CO), and photochemical smog, which are typical of vehicle pollution.

  • Sulfur trioxide irritates the mucous membranes of the respiratory tract. A concentration of 1 volume of SO3 in a million volumes of air (one part per million or 1 ppm) is enough to cause coughing and choking. Sulfur trioxide dissolves in water to form sulfuric acid, which is a strong acid capable of corroding or destroying many materials. Sulfur trioxide can absorb moisture from the atmosphere to form very fine droplets of sulfuric acid. Inhalation of these droplets can harm the respiratory system. Chronic exposure leads to a much greater likelihood of suffering from bronchitis.
