Forest Myths Exploded
There is much more to a tree than wood, fruit and leaves. An Indian scientist estimates the worth of environmental services rendered by a tree over a 50 year lifespan to be IRs 1.57 million — four times the average Indian's income over a similar period. Calculated into the figure is oxygen production worth IRs 2,50,000, soil conservation and fertility maintenance worth' the same, water recycling and humidi ty control (IRs 300,000), and air pollution control (IRs 500,000).
These figures, contained and analysed in the latest publication of the New Delhi-based CSE may be fanciful, but nevertheless represent an attempt to de sig an environmental cost-benefit analysis which will help national planners decide "whether it (economic growth) is not being obtained today at the cost of discounting our future."
