The capital Dhaka was once a dream city for people from other parts of the country. Some used to come here in search of livelihood, others to see the beauty of the capital. Dhaka was once literally a tidy, pollution-free city. But with time that Dhaka is now an Uninhabitable and boring city. Step by step danger is here. The city is now full of concrete and brick with fresh air is like a dream. There is no greening but there are various types of pollution.
