How does population density affect the way people live? population density = number of people/total land area Japan: 880 people/square mile USA: 83 people/square mile
archipelago – chain of islands “Ring of Fire” collision of tectonic plates volcanoes tsunamis earthquakes limited arable land ◦ increases density
Transportation efficient public transit pushers ◦ shove as many people in as possible private cars are limited ◦ high rise parking lots
Housing expensive small 170 sq. ft./person 740 in USA
Land Use Earthquake resistant construction Subterranean construction Creating more land ◦ Filling in wetlands ◦ Destroys valuable habitats Terracing
Health Concerns Pollution ◦ Factory emissions ◦ Sewage and waste water ◦ Toxic chemicals Acid rain Mercury poisoning Disease spreads quickly ◦ Face masks Garbage ◦ recycling
