Chapter Introduction
Section 1: Australia and
New Zealand
Section 2: Oceania
Section 3: Antarctica
Bill Bachman/Wild Light
Interaction The lands of
Australia, Oceania, and
Antarctica range from tiny
islands to massive
continents. Some places in
this region have
environments too harsh for
people to live there
permanently. Others have
attractive climates but few
resources. How might
people survive in a land
with limited resources?
Section 1:
Australia and New Zealand
People’s actions can
change the physical
environment. Extensive
farming and ranching, along
with other agricultural and
economic practices, have
affected Australia and New
Section 2:
Patterns of economic
activities result in global
interdependence. Many of
Oceania’s islands have
limited resources and depend
on tourism or aid from other
countries to support their
Section 3:
All living things are
dependent upon one
another and their
surroundings for survival.
Scientists fear that human
activity may be harming plant
and animal life in Antarctica.
People’s actions can change the
physical environment.

To keep Australia’s people, environment, and livestock
free of disease and pests, the government has enacted
strict quarantine laws. Quarantine means holding
anyone or anything until health or cleanliness can be
proven. Australia inspects incoming people, baggage,
and cargo at its airports, seaports, international mail
centers, and shipping centers. More than 10,000 ships
are inspected every year, as are a million and a half
pieces of mail.

economy, but economic
growth has created serious
challenges for its

Australia (cont.)
• In the late 1980s, a group of Aborigines
filed a lawsuit to block mining on land they
said belonged to their people, and in 1992
a court agreed.

control over land that was being used for
sheep ranches and other economic
Australia (cont.)
• Other Australians are now worried that
they might lose land to such Aborigine
claims, and the government is trying to find
a balance.
Australia (cont.)
• Australia’s prosperous economy is partly
based on the export of mineral and energy
resources such as iron ore, nickel, zinc,
bauxite, gold, diamonds, coal, oil, and

In the island country of Palau there is a small lake that
is home to between 10 and 20 million jellyfish. They
range from marble-sized to larger than a softball. This
habitat has been invaded by the non-native sea
anemone. Scientists working to control the anemone
believe the first one was carried in by a tourist and that
if the anemone population grows, the jellyfish
population will be endangered.
Although small in population,
Melanesia includes diverse
groups of people.
Melanesia (cont.)
• Papua New Guinea occupies the eastern
half of the island of New Guinea and
several hundred smaller islands.
• Nearly all of its people belong to different
Papuan or Melanesian ethnic groups,
which are closely related, and they speak
more than 700 languages.
Melanesia (cont.)
• Many people in Papua New Guinea live by
subsistence farming.
• Others work on plantations that grow
coffee, oil palm trees, cacao trees, and
coconut palms.
• Coconut oil from copra, the meat from
dried coconuts, is used to make
margarine, soap, and other products.
Melanesia (cont.)
• Copra and other plantation products are
produced for export, so food must be
imported for city dwellers.
• Papua New Guinea also supports its
economy by extracting oil, gold, copper,
silver, iron, and zinc from deposits in the
land and ocean floors.
Melanesia (cont.)
• On the other islands of Melanesia, most of
the people belong to different Melanesian
ethnic groups.
• In the Fiji Islands, the population is about
evenly divided between Melanesians and
South Asians.
Melanesia (cont.)
• The struggle between Melanesians and
South Asians for control of Fiji’s
government has made foreign companies
afraid to invest there and has kept tourists
away. Both have hurt Fiji’s economy.
Melanesia (cont.)
• Most people in the Solomon Islands are
ethnic Melanesians who live by
subsistence farming and fishing. Most
follow traditional ways.
Melanesia (cont.)

Micronesia, the Marshall Islands, Palau,
Nauru, and Kiribati have become
Micronesia and Polynesia (cont.)
• People on the volcanic and fertile high
islands practice subsistence farming,
growing yams, sweet potatoes, and
• People on the low islands fish and grow
breadfruit, taro, and bananas.
• Poor soil limits farm production, so most
food is imported.
Micronesia and Polynesia (cont.)
• The Federal States of Micronesia and the
Marshall Islands have phosphate, a
mineral salt used to make fertilizer, but
they lack the money to mine the resource.
• Kiribati’s phosphate deposits are gone,
and Nauru’s are almost gone.
• Kiribati is dependent on foreign aid, but
Nauru is investing abroad and trying to
develop service industries.
Micronesia and Polynesia (cont.)
• Polynesia is a vast island area that lies
southeast of Micronesia.

subsistence farming.
• Several island economies depend on
foreign aid.

industries, and both also earn money by
exporting timber.

by establishing a program to replant trees
as they are cut down.

as cash crops.
• Other import industries in Polynesia
include canning tuna and issuing colorful

music, dance, handicrafts, and tattoos.
Micronesia and Polynesia (cont.)
• In the late 1940s, the United States and
other countries tested nuclear weapons in
the Pacific area, exposing residents of
nearby islands to radiation that caused
deaths and illnesses and poisoned the
land, water, and vegetation.
• The United States has provided millions of
dollars to help Marshall Islanders affected
by the atomic tests.
Micronesia and Polynesia (cont.)
• United States aid has been used to clean
up the environment in testing areas.
• Still, by the late 1900s, islanders could not
return to Bikini Atoll, where the United
States began nuclear testing in 1946.
• France planned nuclear tests on an atoll in
French Polynesia but cancelled those tests
as a result of international protests.
Micronesia and Polynesia (cont.)
• Phosphate mining also has caused
environmental damage.
• About 80 percent of Nauru cannot support
human life, and native birds are threatened
by the loss of their habitats.
• Nauru is now seeking international aid to
restore its land.

Each year in December, runners from around the world
meet for the 26.2 mile (42.2 km) Antarctic Ice Marathon.
Temperatures vary, but the average is from 14°F to –
4°F (–10° to –20°C), and officials caution that the
distance plus the cold equal a difficult run—but people
keep coming. They love the challenge and the beauty
of Antarctica!
International Cooperation
Antarctica is a center of
scientific research.
International Cooperation (cont.)
• After Antarctica was first sighted in the
1820s, scientists and seal hunters visited
parts of the coasts, but the interior
remained unexplored until the early 1900s.
• Explorers reached the South Pole in 1911.
International Cooperation (cont.)
• Hoping to find mineral resources, several
countries claimed territory in Antarctica,
but many other countries, including the
United States, opposed the claims.
• During the 1950s, several countries began
to cooperate on scientific research in
International Cooperation (cont.)

Treaty in 1959.

should be used only for peaceful, scientific

used for weapons testing or any other
military use.

climate changes in the region
D. None of the above

Antarctica’s Environment
Climate changes are affecting
Antarctica’s environment.
Antarctica’s Environment (cont.)
• Penguins, seals, fish, whales, and many
kinds of flying birds live in or near the seas
surrounding Antarctica.
• Larger animals, such as whales and seals,
were once hunted nearly to extinction, or
disappearance from the Earth.
Antarctica’s Environment (cont.)
• Higher temperatures from global warming
could lead to the loss of ice in and near
Antarctica, resulting in the loss of plants
that live on that ice.
• These plants form the diet of krill, which is
the main food source for many larger
species of animals.
• Less plant life means less krill, and less
krill threatens the survival of other animals.
Antarctica’s Environment (cont.)
• Scientists warn that an Antarctic ice melt
could raise sea levels around the world,
probably flooding low islands in Oceania
and highly populated coastal cities.
Antarctica’s Environment (cont.)
• A gas called ozone forms a layer around
the Earth in the atmosphere and protects
the Earth from certain harmful rays of the
• In the 1980s, scientists noticed a “hole” in
the ozone layer above Antarctica, caused,
they believe, by human-made chemicals
reacting with the sun’s rays.
