The ozone layer around our Earth protects us from the Sun’s harmful radiations. But who should protect this layer which is in distress due to the use of ozone depleting substances? Since this is a man-made disaster, the responsibility of fixing it lies on us.Have we been successful in restoring the ozone layer?  Yes, to an extent, say researchers of a new study that has studies the dynamics of the ozone layer in Antarctica.  The study shows that there has been a reasonable recovery of healing of the ozone hole, since the signing of the Montreal Protocol in 1987, where the world took action to save the ozone layer.
