Sudha Nambudiri |KOCHI: There is a reason to cheer on the International Ozone Day. The scientists have recorded a perceptible reduction in the ozone depletion levels in the atmosphere.

The recovery of the depleted ozone layer may take 5-15 years more than that estimated earlier, says a recent study. It found that the regeneration of the protective layer will be pushed back from
