Bangladesh has heavy cyclones and natural disasters, due to this many lives are often lost. The country is one of the most densely populated in the world. Cyclones are very common in the Bay of Bengal during the middle of the year, particularly in the south of country in areas like Sundarban, Chittagong, Cox's Bazaar, or in neighboring Myanmar and Republic of India. Despite the many storms, Bangladesh does not have a very effective storm prevention system, and cyclones usually inflict heavy damage.
