Air is the name given to atmosphere used in breathing and photosynthesis. Air supplies us with oxygen which is essential for our bodies. Air contains a variable amount of water vapor‚ on average around 1%‚ while air content and atmospheric pressure varies at different layers‚ air suitable for the survival of terrestrial plants and terrestrial animals is currently only known to be found in Earth’s troposphere and artificial atmospheres. Air is made up of 99% nitrogen‚ oxygen‚ water vapor‚ and inert

Air Pollution Are you doing everything you can do to live a long and healthy life‚ eating healthy‚ exercising? Well that might not be enough‚ everyday the air you breathe can reduce life expectancy by 2 to 3 years; and an estimated total number of 6.3 million deaths caused by air pollution (Air Pollution kills). Air pollution has been going on for years and takes many forms‚ it is harming our environment and killing us slowly; in order to solve this problem the people of the world need to start

Pollution is the introduction of contaminants into the natural environment that causes adverse change. Pollution can take the form of chemical substances or energy‚ such as noise‚ heat or light. Pollutants‚ the components of pollution‚ can be either foreign substances/energies or naturally occurring contaminants. Air Pollution: Air pollution is the introduction

Air pollution by Chris Woodford. Last updated: September 14‚ 2014. There’s nothing quite like opening the door and breathing fresh‚ clean‚ air—but how clean is the air you’re breathing right now? Unless you’re a scientist with a chemistry lab at your fingertips‚ there’s no real way of knowing. The gases you’re sucking up through your nose could be slowly killing you: according to the World Health Organization‚ around two million people die prematurely from the effects of polluted air every

Air Pollution * Pollutants enter the air from various sources‚ but burning of fossil fuels contributes the most to air pollution. * Exhaust fumes from vehicles contains soot (tiny carbon particles)‚ lead (from cars using unleaded petrol)‚ carbon monoxide‚ oxides of nitrogen and hydrocarbons due to the incomplete combustion of fossil fuels. * Burning of fossil fuels in the combustion engines of vehicles and electrical power stations also releases large amount of carbon dioxide into the

[pic]! [pic] ‘I’ll go out for a breath of fresh air’ is an often-heard phrase. But how many of us realize that this has become irrelevant in today’s world‚ because the quality of air in our cities is anything but fresh. The moment you step out of the house and are on the road you can actually see the air getting polluted; a cloud of smoke from the exhaust of a bus‚ car‚ or a scooter; smoke billowing from a factory chimney‚ flyash generated by thermal power plants‚ and speeding cars causing dust

1. Introduction The Air- the atmosphere around us play an enormous part in our lives. It provides oxygen and other gases that are essential for the survival of human being and plants. The appearance of it is the only thing that would make the Earth different from other dead-planet. However‚ in recent year‚ the technological development has led to over-use harmful toxic; the Air now has been seriously damaged not only in developed countries but also in developing nations like Vietnam.

Essay 1 Air Pollution: Causes and Effects It keeps us alive but at the same time‚ it can also be harmful. We breathe air everyday. Air provides us with oxygen that is essential for living. Nitrogen‚ water vapor‚ and inert gases comprise air along with oxygen. Emission of substances that contaminate air results to pollution. Causes Air pollution is both natural and human-based. Natural air pollution is caused by phenomenon such as volcanic eruption‚ wind erosion‚ decomposition and radioactive

Air pollution in India is a serious issue with the major sources being fuelwood and biomass burning‚ fuel adulteration‚ vehicle emission and traffic congestion.[1][2] India has a low per capita emissions of greenhouse gases but the country as a whole is the third largest after China and the United States.[3] A 2013 study on non-smokers has found that Indians have 30% lower lung function compared to Europeans.[4] The Air (Prevention and Control of Pollution) Act was passed in 1981 to regulate air
