Our personal transportation choices have a huge impact on air quality. What we drive and how we drive impacts the environment.

Jerry Spiegel and Lucien Y. Over the course of the twentieth century, growing recognition of the environmental and public health impacts associated with anthropogenic activities discussed in the chapter Environmental Health Hazards has prompted the development and application of methods and technologies to reduce the effects of pollution. In this context, governments have adopted regulatory and other policy measures discussed in the chapter Environmental Policy to minimize negative effects and ensure that environmental quality standards are achieved. The objective of this chapter is to provide an orientation to the methods that are applied to control and prevent environmental pollution. The basic principles followed for eliminating negative impacts on the quality of water, air or land will be introduced; the shifting emphasis from control to prevention will be considered; and the limitations of building solutions for individual environmental media will be examined.

Air pollution is a major concern of new civilized world, which has a serious toxicological impact on human health and the environment. It has a number of different emission sources, but motor vehicles and industrial processes contribute the major part of air pollution. According to the World Health Organization, six major air pollutants include particle pollution, ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead. Long and short term exposure to air suspended toxicants has a different toxicological impact on human including respiratory and cardiovascular diseases, neuropsychiatric complications, the eyes irritation, skin diseases, and long-term chronic diseases such as cancer. Several reports have revealed the direct association between exposure to the poor air quality and increasing rate of morbidity and mortality mostly due to cardiovascular and respiratory diseases. Air pollution is considered as the major environmental risk factor in the incidence and progression of some diseases such as asthma, lung cancer, ventricular hypertrophy, Alzheimer's and Parkinson's diseases, psychological complications, autism, retinopathy, fetal growth, and low birth weight.

Environmental Studies - Pollution and Control

Environmental pollution or simply pollution refers to undesirable changes occurring in the physical, chemical, and biological composition of natural environment consisting of air, water, and soil. Pollution also means the presence of harmful pollutants in an environment that makes this environment unhealthy to live in. Natural environment has an inbuilt capacity to replenish the losses or reduction in its constituents to restore it as sustainable and healthy as required. Ever expanding population and evolution of man into modern homo sapiens have led to rapid urbanization, industrialization and unprecedented rise in human habitations. All these human endeavors have, in turn, virtually perpetuated deforestation, loss of habitats for flora and fauna, depletion of natural resources at a large scale over the last couple of centuries, which have told upon the inherent resilience of the natural environment. As a result, natural environment continues to be undesirably polluted.

Environmental sustainability implies meeting our current needs without jeopardizing the right and the ability of future generations to meet theirs. Opportunities should be identified and taken to reduce the production of wastes and the use of toxic materials, to prevent soil, water, and air pollution and to conserve and reuse resources, as feasible. Environmental pollution with its health impacts is a key issue for sustainable environment United Nations General Assembly Sustainability and sustainable development focuses on balancing that fine line between competing needs, our need to move forward technologically and economically, and the needs to protect the environments in which we and others live. Sustainability is not just about the environment Kates et al. Sustainability has become a wide-ranging term that can be applied to almost every facet of life on Earth, from local to a global scale and over various time periods.

Сьюзан бросилась к двери, моля Бога, чтобы Стратмор в этот миг включил резервное энергоснабжение и дверь открылась. Увы, ее руки уперлись в холодное стекло. Хейл с перепачканным кровью лицом быстро приближался к. Его руки снова обхватили ее - одна сдавила левую грудь, другая - талию - и оторвали от двери. Сьюзан кричала и молотила руками в тщетной попытке высвободиться, а он все тащил ее, и пряжка его брючного ремня больно вдавливалась ей в спину. Хейл был необычайно силен.

 Черт его дери! - почти беззвучно выругалась Сьюзан, оценивая расстояние до своего места и понимая, что не успеет до него добежать. Хейл был уже слишком близко. Она метнулась к буфету в тот момент, когда дверь со звуковым сигналом открылась, и, остановившись у холодильника, рванула на себя дверцу.

Эхо выстрела слилось с царившим вокруг хаосом. Сознание гнало ее вперед, но ноги не слушались. Коммандер. Мгновение спустя она, спотыкаясь, карабкалась вверх по ступенькам, совершенно забыв о таящейся внизу опасности.
