some Demographics of Mega Cities by Steve Jones
Cities are growing at a rate of around 1 million people every week.
Half the Earth's population will soon live in congested, urban
regions mainly in the poor, developing countries of the South.

If the 20th century was the century of urban sprawl, the 21st
century will be the century of the megacity. A megacity is defined
as a city with an estimated population of more than 10 million

The 10 largest megacities in the world as of the year 2000 are:

1. Tokyo, Japan 26.4 million
2. Mexico City, Mexico 18.4 million
3. Bombay, India 18.1 million
4. Sao Paulo, Brazil 17.8 million
5. Shanghai, China 17.0 million
6. New York City, USA 16.6 million
7. Lagos, Nigeria 13.4 million
8. Los Angeles, USA 13.1 million
9. Calcutta, India 12.9 million
10. Buenos Aires, Argentina 12.6 million

Currently, there are an estimated 23 megacities worldwide. By
2015, the number of megacities is expected to grow to 36.

Today, Asia has 9 megacities; Beijing, Bombay, Calcutta, Jakarta,
Osaka, Seoul, Shanghai, Tianjin and Tokyo- and it will soon have
4 more, including Bangkok, Dhaka, Karachi and Manilla. Relative
to their level of development, Asia has a greater proportion of
their urban population in megacities than in any other region in

The world's megacities take up just 2 percent of the Earth's land
surface, yet they account for roughly 75 percent of industrial wood
use, 60 percent of human water use, and nearly 80 percent of all
human produced carbon emissions. These figures suggest that the
struggle to achieve an environmentally sustainable economy for
the 21st century will be won or lost in the world's urban areas.

It is projected by international development agencies that more than
300 cities with over a million inhabitants will have formed in our
world by 2025. 

Between 1990 and 2025, the number of people living
in urban areas is projected to double to more than 5 billion- 90
percent of that increase will occur in developing countries. The
explosion and growth of megacities worldwide is unsustainable,
unprecedented and ecologically disasterous for human civilization.

Sustainable urban development requires realistic limits on any
given region's natural carrying capacity, hard-core conservation
and recycling of local finite natural resources, the promotion of
limitless decentralized alternative energy sources, and a radical
shift into environmental, economic and social development
alternatives that promote healthy and advanced living
arrangements and environments for future urban dwellers
worldwide for the 21st century.
