Do you know Breathing Oxygen Cost?

 The cost of Oxygen. Very interesting!!! 

 In one day a human being breathes oxygen equivalent to three cylinders. 

 Each oxygen cylinder on an average costs Rs 700, without subsidy. 

 So in a day one uses Oxygen worth Rs 2100 and for a full year it is Rs 7,66,500. 

 If we consider an average life span of 65 years; the costs of oxygen we use become a staggering sum of  

Rs 50,000,000. (Rs 50 million) 

 All this oxygen is derived free of cost from the surrounding trees... 

 Very few people look at trees as a resource and there is rampart tree cutting going on everywhere which should stop.  

 Please convey this to your friends and care for trees.
