2. What can you notice in respect to the distribution of mega cities on the world map?
Especially in recent years mega cities in developing countries are increasing in size and number. In the industrial countries there are comparativly less mega cities. The largest cities on earth are now Tokyo, Mexico City and New York.
3. Estimate possible consequences of this rapid urbanisation.
In the developing world, the rural-urban-migration is one of the main reasons for increasing urbanisation. People are moving from rural to urban areas because of so called push- and pull-factors, like for example the dream of a better life, or the hope for more employment possibilities in the cities. For the industrial countries, New York is since centuries the destination of thousands of migrants. Lot's of them migrate not only to find work and earn money, but also because they hope for succes and fortune.
