Mr Tony's Geography Stuff

To be a megacity like this, you have to conform to urbanization. There is no possible way to have such a populated and crowed city with farmlands around. This is a place of business yet residential areas, it also is where the marketplaces are and where kids go to school. Megacities need to be a part of an urban society in order for them to stay afloat.

This is a great introduction to the demographic explosion of the slums within megacities.  This is applicable to many themes within geography.   

I can't image or even relate to the experience of living in a place like this. With rivers polluted right outside your house. And those rivers are what people bathe in and wash their clothes. I can't imagine not being able to access clean drinking water or lacking food. The people in Dhaka endure so much their whole lives, a good percentage of them will always live in poverty.
