Smog identifies gasses and pollutants released in to the air/atmosphere. Common pollutants for example carbon dioxide, carbon monoxide, methane and chlorofluorocarbons (CFCs) may cause numerous trouble for both the Earth itself (ozone layer depletion and climate change), as well as for individuals breathing in the polluted air.

Some of the main consequences of air pollution are:



Ozone depletion

Chlorine atoms present in gases including refrigerants and CFCs destroy ozone molecules in the atmosphere. The Earth's ozone layer provides a barrier preventing much of the UV radiation from your sun reaching the surface of the planet. The thinner the ozone layer becomes, the harder UV radiation has the capacity to penetrate through. This UV radiation can harm the cells of most living things, causing melanoma and crop failure.



Greenhouse Effect

Whilst not enough ozone is an issue, too much of gasses such as co2 and methane likewise have negative consequences. Referred to as greenhouse gasses, they work like a greenhouse by getting thermal radiation in but keeping the majority of it trapped. This net one of the ways effect causes an increase in temperature. Under stable conditions, the identical amount of thermal radiation would be lost as is absorbed, maintaining an equilibrium. But an increase in the layer of such greenhouse gasses will trap more heat in than can escape. The following increase in temperature causes problems such as melting the polar ice caps which raise sea levels and cause flooding to low-lying land, along with causing more extremes in seasons which threatens wildlife survival and also the natural rhythm of life.



Smog

Large cities containing millions of people create a great quantity of emissions. Along with some being harmful in their own right, these gases can also react with one another to create secondary pollutants and ozone, causing trouble for people like skin irritation and respiratory complaints.



Acid Rain

When some types of gas such as sulphur dioxide or hydrogen chloride are freed in to the atmosphere, they interact with the water to make acids like sulphuric acid, which falls to the ground as acid rain. Besides this corrode and damage buildings, it will harm/kill wildlife and vegetation.

The growing industrialisation with the world's nations has triggered progressively more factories being built, along with more power generation facilities that are required to support them. As well as this, citizens in countries including India and china have become wealthier, allowing many to purchase an automobile the very first time. The sheer size their respective populations implies that the issue of harmful emissions in to the planet's atmosphere probably will get a good deal worse.
