The human population is growing at an alarming rate. By 2050, there will be almost 10 billion people on the planet. 

We've been hearing this for years, but where is the most growth happening? 

Today, Tokyo is the most populous city in the world, with about 38 million residents. None of the 10 most populous cities in the world are in Africa, and only two (Sao Paulo and Mexico City) are in Latin America.
