Dhaka is extremely overpopulated capital city of Bangladesh. Because of drought, famine, water salinity around the country encouraged mass migration to Dhaka. In reality, the city itself lost its capacity to accommodate more people. Brick kilns are taking places into green spaces and growing more high rising buildings everywhere around city. No one can find a place to have a pure breath. The main river Buriganges in the city is nearly dead because of huge industrial pollution. Though Bangladesh is proceeding towards industrialization it requires being very careful regarding environmental impacts. Otherwise the whole nation has to suffer in the long run.
