After a lot of thought I was struggling to choose the mega on which I would focus the project on so I did my research on mega cities and the problems they have. There are 24 mega cities in existence as of 2013, the biggest ones are Tokyo, Delhi, Mexico City and New York.

The growth of mega cities can be caused by immigration, the challenges that mega cities face is lots of slums and homeless people. With growing population they don’t have enough housing for all the people which leads to homeless people and rising numbers of people in poverty.

There is also problems with traffic congestion and air pollution with higher numbers of traffic passing through the cities this causes the traffic to become stuck and cause a lot of air pollution. This is bad for environmental reasons and the weather e.g. smog over the cities. There also becomes slight problems when the cities build outwards into other areas meaning more travel for work therefore more cars etc.
