Ozone layer and how it is getting depleted.
Ozone (O3) is a molecule formed by three oxygen atoms. There is a layer of ozone in the stratosphere. It is a deadly poison. It is known to cause skin cancer in human beings. However, at the higher levels of the atmosphere, it acts as a natural sun-block and shields us from UV radiations of the sun which are dangerous to living organisms. Ozone depletion is the sharp reduction of ozone in the stratosphere due to chlorofluorocarbons (CFC’s) used as refrigerants and in fire extinguishers.
O+O2 -----→ O3 (ozone)
To limit the damage to the ozone layer the release of CFC s into the atmosphere must be reduced. These CFCs should be replaced with environmentally safe alternatives.
Managing the garbage we produce:
Improvements in our lifestyle have resulted in greater amounts of waste material generation. Changes in packaging have resulted in much of our waste becoming non-biodegradable. Increased use of non-biodegradable items has left the environment polluted with them.
