How do human live in extreme environments?

EXTREME LIVING

Humans have found a way of living in some of the most inhospitable environments on Earth – including the scorching deserts, the icy Arctic, and the steamy rainforests. Desert dwellers have to cope with the daily problem of finding water. In the Arctic, the challenges are keeping warm and finding food to eat. The rainforests are full of life, but many of the animals are dangerous, and some of the plants are poisonous.

ARCTIC

The frozen Arctic is one of the toughest places on Earth to survive. There are no plant foods, so Arctic people came to rely on hunting seals, walruses, whales, birds, and fish. Without timber, they used skins and bones to build shelters, sleds, and boats. Modern inventions, such as the snowmobile, have made life in this frozen wilderness easier.

RAINFOREST

Unlike the Arctic and the desert, the South American rainforest has a wide variety of animals and plants. The problem is that many of the animals and birds suitable for eating live high up in the canopy. Hunters scan the trees above for prey, such as monkeys, and then shoot them down using blowpipes firing poison darts.

DESERT

The extremes of temperature faced in the desert – extremely hot during the day, and very cold at night – is the main problem desert dwellers face. They are constantly on the move, searching for fresh water supplies, sometimes using the flight of birds and insects as their guide. Having found water, they must make sure that not a drop is wasted.

Ostrich egg: The San people of the Kalahari Desert, in southern Africa, fill ostrich eggs with water and bury them for using later.

Camels: Bedouins travel using camels, which can go without water for long periods thanks to the fat stored on their backs.

Can you describe the cities?

CITIES

Cities have existed since ancient times, when they functioned as trading hubs, often at the heart of sprawling empires. By the early 20th century, one in 10 people lived in a city. Industrialization has led to massive urbanization, and more than half the world’s population are now city-dwellers. Modern cities are centres of commerce, culture, and government.

CITY-STATE

In Ancient Greece, it was common for cities to establish themselves as independent states, with their own political systems. By the 5th century BCE, there were hundreds of city-states, and Athens was one of the most important. Today, Athens is the Greek capital.

HIGH-RISE

The first high-rise buildings, now known as “skyscrapers”, were constructed in the 1880s. With limited space in city centres, building upwards became the solution. Today, more than 7,000 skyscrapers tower above the city of Hong Kong.

RIVER LIVING

Towns and cities were often built next to rivers, to take advantage of the trading opportunities and transport links they offered. Founded by the Romans, the city of London now spreads far and wide on both sides of the River Thames.

RELIGIOUS CENTRE

Some cities are important religious sites. Mecca, in Saudi Arabia, is sacred to Muslims as the birthplace of the prophet Muhammad. All Muslims should make a pilgrimage to Mecca once in their lifetime.

CONURBATION

When a city expands to merge with neighbouring towns, it becomes one huge urban area called a conurbation. The world’s largest conurbation is Tokyo, Japan, with currently 37 million inhabitants.

PURPOSE-BUILT

Until 1960, the capital of Brazil was Rio de Janeiro on the east coast. However, the government wanted to encourage growth and development in the centre of the country, and so a brand new capital was purpose-built in the interior – the modern capital of Brasília.

POPULATION GROWTH

Until recently, the majority of the world’s population lived in rural areas. Today, most people live in cities, where they have migrated in search of work and opportunity. In many cities, such as Mumbai in India, this has led to overcrowding as temporary shelters spring up on the outskirts.

WORLD HERITAGE

The United Nations Educational, Scientific, and Cultural Organization (UNESCO) has listed sites of outstanding cultural or natural importance in order to preserve them. Called World Heritage Sites, these include cities such as Djenne in Mali, with its large mud brick mosque.

DESERT CITY

At night, the lights of Las Vegas shine out across the Nevada Desert, USA. Las vegas means “the meadows” because the vast city was once just a place where travellers stopped for water as they crossed America.

CITY WITHIN A CITY

Few city-states remain today, but one exception is the Vatican City in Rome, Italy, home of the Pope and the centre of the Roman Catholic Church. The Vatican remains a city-state with its own flag, coins, national anthem, and postage stamps.

What is the importance of festivals in life?

FESTIVALS

Across the world, people celebrate festivals for a range of reasons. Though many form part of religious worship, others were created to mark a change in seasons, to focus on cultural traditions, or to celebrate an important milestone in history. Some festivals take place on the same day every year; others are based on ancient calendars or a new moon, so the dates change. Special food is almost always a part of each festival.

  • CHRISTMAS

This Christian festival celebrates the birth of Jesus Christ, and is celebrated in most countries on 25 December. Traditions include decorating fir trees, exchanging gifts, attending church, and waiting for a visit from Santa Claus.

  • DAY OF THE DEAD

During this Mexican festival, held on 1 November, families believe that the souls of dead relatives are able to return to the land of the living for one night. They decorate altars in homes and cemeteries with candles and flowers.

  • THANKSGIVING

This North American festival is held on the fourth Thursday of November in the USA and the second Monday in October in Canada. Families get together to give thanks for the first good harvest of the European settlers more than 400 years ago.

  • DRAGON BOAT FESTIVAL

This festival is celebrated in East Asia. According to legend, when a Chinese official named Qu Yuan drowned in a river, people rowed out on boats with dragon-head prows and dropped parcels of rice wrapped in bamboo (zongzi) into the water to divert the hungry fish away from his body.

  • MID-AUTUMN FESTIVAL

This East Asian celebration, which dates back more than 3,000 years, falls near the traditional harvest, when the Moon is at its lightest and brightest. Family and friends gather in the evening to eat mooncakes, rich rounds of pastry with lotus-seed fillings.

  • FEAST OF ST LUCIA

Each year, on 13 December, people in Sweden and Norway celebrate the feast of Saint Lucia (a Christian girl who died for her faith). Early in the morning, a young girl dressed in white (often the youngest daughter in the house) takes a tray of hot saffron buns to her family.

  • EID AL-FITR

This Muslim festival marks the end of Ramadan, a month-long fast. The celebration lasts for three days, starting with the sighting of the new moon. People dress in their best clothes and go to the mosque.

  • DIWALI

Also known as the Festival of Lights, Diwali celebrates the victory of good over evil. Hindu families light oil lamps and put them on ledges and balconies. They also send cards with wishes for a good year.

  • PASSOVER

In March or April, Jews celebrate Passover to remember when Moses led the Israelites from slavery in Egypt. Passover lasts for seven or eight days and includes a special meal called a seder. Each part of the meal has a symbolic meaning.

  • EASTER

The Christian festival of Easter recognizes the resurrection of Jesus on the third day after his death. It falls between late March and April each year. People attend church and exchange Easter eggs.

Which are the major Religions in the world?

RELIGION

A religion is a set of beliefs that helps explain life’s mysteries. People seek guidance from their religion on how they should live their lives. Most people with religious faith believe in either one God or many gods. They express their faith through rituals, such as gathering together with others to worship, and by studying sacred books. There are many different religions, but those included here have the most followers around the world.

  • HINDUISM

One of the oldest religions, Hinduism began 5,000 years ago in India. Hindus believe in a supreme spirit, Brahman, who reveals himself through hundreds of gods and goddesses. Hindus practise their faith in different ways, but share a belief in reincarnation – the idea that a person’s soul has lived before and will live on after death in another form.

Krishna This popular Hindu god is thought to bring great happiness to believers.

Ganesh Hindus pray to Ganesh, the elephant god of wisdom and help, when facing a new challenge.

Water shaker In one Hindu ritual, priests sprinkle water over the worshippers.

Om is a sacred Sound, Om, spoken after Hindu prayer.

  • ISLAM

Muslims believe that God revealed his words through an angel to the prophet Muhammad, who collected them in the Qur’an, the holy book. The faithful try to live by the rules in this book. The most important duties are the Five Pillars: prayer, helping the needy, fasting for one month a year, making a pilgrimage to Mecca, and showing faith in God.

Islamic scribe Because the Qur’an is believed to contain God’s exact words, great care is taken when Muslim scribes recreate them.

Prayer beads God, or Allah, is thought to have 99 names. This string of 99 prayer beads can be used to remind Muslims of the many names of the one God.

Qibla Muslims must face the holy city of Mecca when they pray, five times a day.

  • CHRISTIANITY

Christianity is based on the belief that Jesus Christ is God’s son. The Bible, Christianity’s sacred book, contains the story of Jesus’s life and how he was put to death. Christians believe his sacrifice means that followers will have an eternal life with God.

Chalice In the ritual of Holy Communion, bread and wine represent the body and blood of Jesus. The wine is often served in a chalice.

Icon of Christ Paintings remind Christians that God lived as a human through Jesus.

Cross Because Jesus died on a cross, it is a powerful symbol of the Christian faith.

  • BUDDHISM

Unlike most religions, Buddhism is not based on worshipping a god or gods. Instead, it is based on the teachings of the Buddha, who showed his followers how to live a good life and avoid sufffering by controlling their desires. Buddhists hope to achieve true wisdom, known as enlightenment.

Buddha The founder of Buddhism, Siddhartha Gautama, was born in what is now Nepal in 563 BCE.

Statues of Buddha are often made of gold to show his importance

Merit sharing Buddhists believe that if they live caring lives, they will build up merit (good will) and have a better next life. They can pass on merit to others in a merit-sharing ceremony.

  • JUDAISM

This is the religion of the Jews, also called Hebrews. Judaism was the first successful religion based on the idea that there is only one God, and it formed the basis for both Christianity and Islam. Central to Jewish belief is that God chose the Jews as a special holy nation, and gave them a set of laws to follow. The story of the first Jewish people is told in the Hebrew Bible (the Christian Old Testament).

Chanukiah A nine-branched candlestick is used to celebrate Hanukkah, the Jewish festival of light. The central branch holds the candle used to light the others.

Prayer wheel and prayer Buddhist prayer wheel turns, a mantra (a blessing or prayer) written on a scroll inside “repeats” itself over and over again.
