Urbanization and Migration By 1999, the number of megacities (more than 10 million people) was 17, 13 in less-developed regions.

Population Growth and Its Effects on the Environment “As the population grows, our individual slice of the pie gets smaller. ”

Distribution of Resources is Unfair! • Most of the worlds hunger is in the developing world where the majority of the population is. • These people are hungry for many reasons. • Currently, 90% of the worlds wealth is in the hands of 5% of the world’s population.

The more people there are in the world means… • • • the more houses there are to warm the earth the more trees will fall the more people will move into the developed world the more wood and stone and cement that is needed the more pollution the more threat to forests and atmosphere the more to feed the more crime the more HIV/AIDS transmission • there will be less oxygen • there will be less clean water • there will be less slice of pie to eat

Philippines Philippine population: 88, 574, 614 (Aug 2007) Rate: 3 persons per minute Manila is now a megacity! (11, 553, 427) What’s good? Ø 9 out of 10 are literate What’s bad? Ø See next 4 slides!

Source of Lighting (Energy)

LPG or wood? (Energy)

Waste Disposal (Environment)

Zero Population Growth An average Japanese is worth 37, 800 US dollar! Jose Rizal is worth 1, 000 US dollar! Zero Population Growth – Philippines: Not Applicable!

The World needs… a “Demographic Transition”

“How many people can the earth support? ” 10 – 20 billion people! - Cohen, J. 1995. How many people can the earth support? W. W. Norton & Co. , New York “At what level of well-being? ” Extreme poverty! - Statistics.

Statistics predicts! It may not happen if… • Make a bigger pie: Increase human productive capacities through technology and innovation • Put fewer forks on the table: Reduce numbers and expectations of people through family planning, vegetarian diets, others • Teach how to eat a pie: Change the terms of people’s interactions through improved planning and government to enhance social justice
