Summary

Chapter Intro 1

Human-Environment 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?

Chapter Intro 2

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 Zealand.

Chapter Intro 2

Section 2: Oceania

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 economies.

Chapter Intro 2

Section 3: Antarctica

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.

Section 1

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.

Section 1

Australia

Australia has a strong economy, but economic growth has created serious challenges for its environment.

Section 1

Australia (cont.)

• Australia has a huge land area but only 20.6 million people.

• Needing skilled workers to develop resources and build its economy, the government has encouraged immigration.

Section 1

Australia (cont.)

• Most Australians are descended from the first immigrants who were from the British Isles and Europe.

• Today, immigrants come from Asia, South Africa, Latin America, and Oceania.

Section 1

Australia (cont.)

• The Aborigines were the first people to settle Australia, but they have suffered discrimination from white Australians for years.

• Recently the government has worked toward improvements in education, job pay, poverty solutions, and health care, but the problems still exist.

Section 1

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.

• Later court decisions gave Aborigines control over land that was being used for sheep ranches and other economic activities.

Section 1

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.

Section 1

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 natural gas to China and Japan.

• The population of New Zealand consists largely of the descendants of European, especially British and Irish, immigrants.

• There are also people of German, Scandinavian, Croatian, and Dutch backgrounds.

Section 1

New Zealand (cont.)

• The Maori, the first people to settle New Zealand, are the largest non-European group, forming about 15 percent of the population.

• In 1840 Maori leaders signed the Treaty of Waitangi with Great Britain, which acknowledged British rule over the islands and included the promise of the British to protect Maori land rights.

Section 1

New Zealand (cont.)

• Some Maori have charged that since 1840, Europeans unfairly took land from them.

• They use the Treaty of Waitangi to win lawsuits recognizing their right to land.

• Some people of European descent fear these lawsuits will cause them to lose their land and livelihood.

Section 1

New Zealand (cont.)

• The population growth rate among Pacific Islanders, East Asians, Southeast Asians, and the Maori in New Zealand is high, but the growth rate among whites is low, indicating a future change in the ethnic balance of the country.

Section 2

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.

Section 2

Melanesia

Although small in population, Melanesia includes diverse groups of people.

Section 2

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.

Section 2

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.

Section 2

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.

Section 2

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.

Section 2

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.

Section 2

Melanesia (cont.)

• Most people in the Solomon Islands are ethnic Melanesians who live by subsistence farming and fishing. Most follow traditional ways.

Section 2

Melanesia (cont.)

• Most people in Vanuatu are farmers, although tourism is increasing.

Micronesia and Polynesia (cont.)

• Micronesia and Polynesia are made up of high volcanic islands and low, ring-shaped atolls.

• Since the 1970s, the Federated States of Micronesia, the Marshall Islands, Palau, Nauru, and Kiribati have become independent.

Section 2

• People on the volcanic and fertile high islands practice subsistence farming, growing yams, sweet potatoes, and cassava.

• People on the low islands fish and grow breadfruit, taro, and bananas.

• Poor soil limits farm production, so most food is imported.

Section 2

• 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.

Section 2

• Polynesia is a vast island area that lies southeast of Micronesia.

• Today, after a period of European rule, some Polynesian islands, such as Samoa and Tonga, are independent.

• Others, such as French Polynesia, are still controlled by European countries.

Section 2

• Many people in Polynesia practice subsistence farming.

• Several island economies depend on foreign aid.

• Samoa and Tonga have built strong tourist industries, and both also earn money by exporting timber.

Section 2

• Samoa has tried to prevent deforestation by establishing a program to replant trees as they are cut down.

• Tonga grows vanilla beans and coconuts as cash crops.

• Other import industries in Polynesia include canning tuna and issuing colorful postage stamps for collectors.

Section 2

• The people of Samoa are known for their music, dance, handicrafts, and tattoos.

Section 2

• 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.

Section 2

• 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.

Section 2

• 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.

Section 3

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!

Section 3

International Cooperation

Antarctica is a center of scientific research.

Section 3

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.

Section 3

• 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 Antarctica.

Section 3

• Twelve countries signed the Antarctic Treaty in 1959.

• This agreement stated that Antarctica should be used only for peaceful, scientific purposes.

• It specified that Antarctica could not be used for weapons testing or any other military use.

Section 3

• Since 1959, forty-five countries have signed the Antarctic Treaty.

• These countries have agreed to forbid mining in Antarctica and to protect its environment.

Section 3

• Geologists have found the remains of trees from millions of years ago.

Section 3

Antarctica’s Environment

Climate changes are affecting Antarctica’s environment.

Section 3

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.

Section 3

• 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.

Section 3

• 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.

Section 3

• A gas called ozone forms a layer around the Earth in the atmosphere and protects the Earth from certain harmful rays of the sun.

• 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.
