Carbon dioxide, a miscreant posing hazard to Earth's ozone layer, is one
 of the major constituent gases of the "Green House Gasses". Carbon 
dioxide is a gas that is emitted while burning fossil fuels or through 
cars and other modes of transportation or as industrial effluents that 
cannot escape from our atmosphere and thus gets trapped. Although carbon
 dioxide is required and utilized by plants to manufacture oxygen 
besides biosphere, the oceans account for removal of about 57% of human 
emitted carbon dioxide.
Huge
 quantities of carbon dioxide due to industrialization and cutting down 
of trees affect the carbon dioxide ratio and causes the phenomena of "global warming". This "global warming" thus caused, melts polar ice caps
 and in turn affects rising water levels. These factors further cause 
extinction of birds and animals and submersion of land, countries and 
cities into water. Besides, increased carbon dioxide lead to acid rains 
and smog, which is a combination of fog and suspended gas together with 
other air pollutants, which cause respiratory diseases and other 
ailments.
