Natural calamity means natural disaster caused by the nature. Bangladesh is a land of natural calamities. These calamities are flood, cyclone, earthquake, tidal bores, excessive rainfall, drought, river erosion, and earthquake. Almost all of these natural calamities visit Bangladesh every year, and we count a heavy loss every year owing to these natural calamities.

There are some causes behind these natural calamities. Environmental pollution, climate change, global warming, greenhouse effect, deforestation, lack of plans etc. are responsible for these natural calamities. The effects of natural calamities are dangerous. They cause a great loss to our life and properties. Many people suffer untold sufferings. They become homeless and helpless. Houses are destroyed, cattle are washed away, crops are greatly damaged and trees are uprooted. The prices of all essentials go up. Famine breaks out. Thousands of people and animals die for want of food. Many dangerous diseases like cholera, typhoid, diarrhoea and dysentery break out in an epidemic form. The educational institutions are closed down for a long time. In a word the whole nation undergoes extreme sufferings and socio-economic pressure.

Though we cannot prevent natural disasters as we have no hand in nature, we can reduce the damage caused by natural calamities. The government as well as the conscious citizens should come forward to raise public awareness to reduce the losses caused by natural calamities.
