According to geographers’ estimates, two out of three people in the world will live in a city by the year 2030. This migration to urban centers creates an increase in urban populations, resulting in the formation of megacities. Geographers define a megacity as any city with a population of more than 10 million people. Today, there are over 30 megacities in the world. Use the internet to research the names and locations of the world’s megacities. Then pick two cities, research them further, and create a profile about them. For each city, include the following information: location brief history of the city population density problems currently facing the city what city planners are doing to address the city’s problems what city planners could be doing differently
