In one day a human being breaths oxygen equivalent to 3 cylinders. Each oxygen cylinder costs Rs 700.00, without subsidy.
So in one day one uses Oxygen worth Rs 2,100.00 and for full year it is
Rs 7,66,500.00. And if consider average life span of 65 years; the cost of Oxygen we use becomes staggering amount of Rs 500,00,000. 00 or Rs 50 millions. All this OXYGEN is derived free of cost from surrounding trees.
Very few people look at a tree as a RESOURCE and there is rampant tree cutting going on everywhere which must stop.
Do give it a thought, please.
