Ozone layer preservation

The international day for the preservation of ozone layer was observed on September 16, 2008 with focus on combating the depletion of earth's fragile protective shield. Recent studies have indicated a connection between dangerous diseases like brain diseases to environmental pollution.
A multitude of health problems, such as cancer, have surfaced as a direct consequence of depletion of ozone layer. The steps taken recently by the City Nazim Syed Mustafa Kamal to plant more than 150000 trees in the city will indeed help to counter pollution resulting in the preservation of ozone layer. On a personal level too we need to take steps that conserve our natural resources and prevent us from further polluting our environment.
