Objectives

This chapter should enable you to:

Appreciate the economic prominence of larger, Europeanized Australia and New Zealand in a vast sea of small, mainly indigenous political units struggling to make a living

Recognize the associations between the physical geographies of islands, their typical social and political organizations, and their economic characteristics

Objectives (cont’d.)

Understand how minority control of most of the wealth generated by mineral and other resources has led to discontent and rebellion among majorities

Hear the concern expressed by low-lying island countries about the production of greenhouse gases in faraway industrialized nations

Understand the obstacles faced by indigenous people in winning legal recognition of ancestral claims

Objectives (cont’d.)

Appreciate the process by which Australia and New Zealand are loosening ties with their ancestral European homeland and strengthening their regional orientation

Learn about “unclaimed claims” to the continent of Antarctica

Island Types

Continental islands

Islands on the continental shelves or were attached to continents before sea level rise and tectonic activities isolated them

Examples: Australia, New Guinea, New Britain, New Zealand

High islands

Often the result of volcanic eruptions

Examples: Hawaii, Samoa, Society Islands

Island Types (cont’d.)

Low islands

Made of coral

Most take the shape of an irregular ring surrounding a lagoon (called an atoll)

Lack resources to support dense populations

Examples: Kiribati, Caroline and Marshall Islands

Island Types (cont’d.)

Land use

Evenly divided between rural and urban

Main cities and seaports on volcanic high islands

Support a diversity of crops

Why Are Oceania’s Ecosystems So Vulnerable?

Factors threatening endemic species

Human-induced extinctions

Volcanic eruptions

Typhoons (hurricanes)

Rises in sea level

Hawaii as “extinction capital of the world”

Commercial logging in New Guinea

Home of 22,000 plant species, of which 90% are endemic

Ancestors of today’s Aborigines

Languages

Linguistic legacy

Aboriginal, Austronesian, and Papuan

The Indigenous Peoples of Oceania

Linguistic complexity

Papua New Guinea is home to 850 languages; mainly Papuan but also Austronesian

Vanuatu has fewer than 200,000 people and 105 identified languages

Lingua Franca

English and French reflect colonial past

Pidgin is official language of Papua New Guinea

Geopolitical Issues

Oceania was once entirely colonial

The U.S., Britain, Australia, and New Zealand have abandoned most of their colonies

Only France has held on to all of its colonies

Why are Foreign Powers Interested in the Pacific?

Importance of islands

Military advantages

Economic advantages

French Polynesia used for atomic testing

23

Oceania’s Environmental Future

Rise in sea level due to global warming

Kiribati, Marshall Islands, and Tuvalu could be completely submerged, while other island nations would lose territory

Alliance of small island states

Politicked unsuccessfully at 1997 Kyoto Conference for lowering of global greenhouse gas emissions to 20 percent below their 1990 levels by 2005

Took legal recourse against U.S. and Australia for failing to ratify the Kyoto Protocol

24

Australia and New Zealand

Similar in population, cultural heritage, political problems and orientation, type of economy, and location

Products of British colonization and reflect British heritage

Prosperous countries

Relatively few people among whom to spread wealth

Both owe their prosperity to wholesale transplantation of business culture and technology from the UK

25

Australia and New Zealand (cont’d.)

Despite their independence, remain loyal to Britain

Political orientation

Since WWII, these two countries have sought closer relations with the U.S., and British influence has waned

Seeking stronger roles in the Pacific Basin’s economy

Australia’s Original Inhabitants Reclaim Rights to the Land

Aborigines

Population

An estimated 300,000 to 1 million Aborigines and Torres Strait Islanders inhabited Australia when Europeans arrived in the 17th century

Colonizing whites slaughtered many and drove the rest into marginal areas of the continent

Today, there are an estimated 600,000 Aborigines and Torres Strait Islanders, living mainly in the tropical north of the country

27

Australia’s Original Inhabitants Reclaim Rights to the Land (cont’d.)

Aborigines suffer from:

High infant mortality rate

High unemployment

Low life expectancy

Contention between Aborigines and white majority over land rights

Aborigines increasingly enlisting aid of geographers and other social scientists to document, measure, and analyze traditional land claims

Exotic Species on the Island Continent

Exotic species – non-native plants and animals introduced into an ecosystem

Impact often catastrophic to native species

Islands sensitive to ecological disruption

Exotic species that have caused problems in Australia include:

Rabbits, foxes, mice, water buffalo, cane toads, prickly pear cactus, sheep, cattle, dromedary camels

Antarctica: The White Continent

World’s fifth largest continent

5.5 million square miles

Climate

Summers include “whiteouts” caused by light refraction on snow and ice covering about 95% of the continent

Winters are mainly dark, with average temperatures the coldest in the world

Antarctica: The White Continent (cont’d.)

“Ozone Hole” concentrated seasonally over Antarctica

Important locale for scientific research
