IS THERE A CHANCE OF EXAUSTING OF OXYGEN IN THE AIR, DUE TO THE INCREASE IN POPULATION?

மரங்களும் ஆக்ஸிஜனும்

An average man breathes air of from 7 liters to 8 liters of air daily. There is 20% of oxygen in the air.

Our body takes inside only 1/4thth of the oxygen.  The remaining 3/4th comes out in the breathing out air. This, an average man uses an average of 550 liters of oxygen daily. The oxygen, thus breathed in within the body comes out in the form of carbon-dy- oxide.

During photosynthesis we know that plants inhale carbon-dy –oxide and sent out oxygen. A tree with a circumference of 50cm and a height of 30 – 40 meter produces   an average of 92 liter oxygen. i.e. an average of 7  trees fulfils the  daily requirement of oxygen of a man.

              As per the statistical analysis of the satellites we come to know that there are roughly 400 billion trees in the world.  i.e. the oxygen required of 57 billion  people are released by the trees of the world  annually.  The population of the world at present is only 7.7 billion.

similarly, oxygen is required by other living beings also.  oxygen is also required far operating car engines and other engines also.  a research tells that because of using various solid  fuels the quantity of  carbon-Dy- oxide  in the space rises roughly  annually  at the rate of  2.2 ppm  . i.e the quantity of oxygen also is reduced.  we can assume that after 50,000 years   the quantity of oxygen  will reduce by 1:%. therefore there is no immediate danger.
