Cost of Oxygen

PNLIT Trustee Prasanna recieved this as an email forward.

The mathematics of it is very interesting!

In one day a human being breathes oxygen equivalent to 3 cylinders.
Each oxygen cylinder on an average costs Rs.700/-, without subsidy.

So, in a day one uses oxygen worth Rs 2,100/- and for a full year it is Rs 7,66,500/-. And, if we consider an average life span of 65 years, the cost of oxygen we use becomes a staggering sum of Rs 500,00,000/- (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 rampant tree cutting going on everywhere which must stop.

CARE FOR TREES!
