WORLD ATLAS – RUSSIA

Stretching between two continents, Europe and Asia, Russia is the largest country in the world. Until 1991 it was part of the Soviet Union. Most of Russia’s population lives west of the Ural Mountains, in the European part, many in the big cities of Moscow and St. Petersburg. Also in this area lies a good part of Russia’s farmland, producing cereals and root crops.

East of the Ural Mountains is Siberia, a vast area of sparsely populated land. The climate is harsh, with frozen tundra in the north and thick coniferous forest, known as taiga, further south. The deepest lake in the world, Lake Baikal, is found in the south-east. Siberia is rich in coal, oil, gas and metal ores. The region has a small population, but a large number of different peoples.

Scattered around the fringes of the Arctic Ocean are a number of small communities. They herd reindeer or cattle, and use animal skins to keep warm as their ancestors did.

The Trans-Siberian Railway runs from Moscow across the southern part of Siberia. It is a vital link for people and industry between east and west. The longest line in the world, it takes eight days to travel.

Since the collapse of the Soviet Union, Russia, for all its natural mineral wealth, long-established industries and advanced technology, is struggling to develop its economy.

CENTRAL ASIA

Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan are the Central Asian republics. Much of the region is desert and dry grassland, with mountains to the south. There are reserves of coal, gas and metal ores.

South of the Caucasus mountain range lie Georgia, Azerbaijan and Armenia. Their fertile land produces many crops, and also has reserves of oil and gas. The Caucasus contains many different ethnic groups and often experiences conflict.

WORLD ATLAS – SOUTHEAST EUROPE

The Balkans, which makes up most of south-east Europe, are lands of rugged mountains and deep valleys. Winters are cold, but cotton, tobacco and grapes can be grown in the warm summers. Several of these countries were once part of Yugoslavia. The creation of new borders, as well as clashes between ethnic groups, has led to conflict.

Greece is one of the oldest nations in Europe. As a mountainous country, farming space is limited, and its olive groves and vineyards are scattered along the hillsides. Greece has many islands, and a large part of its economy relies on a large shipping industry and tourism.

Turkey is split between Europe and Asia by a narrow stretch of water called the Bosporus. Turkey’s coasts are warm, but the dry grasslands of its interior can be bitterly cold in winter. Turkey is famous for its craft industry, especially carpets and pottery. Its Mediterranean coastline and ancient sites also make it a popular tourist destination.

WORLD ATLAS – CENTRAL AND EASTERN EUROPE

Much of central and Eastern Europe is flat, low-lying land. A large part of this is given over to farming, but native forest still remains in upland areas, where elk, wolves and bison roam. The northern part of this region has warm summers but cold winters. Crops such as potatoes and cereals are grown, and animals are farmed for their milk and meat.

Heavy industries such as mining, metal-working, car production and glass-making are important for the economy of Poland. Pollution from the burning of coal to produce electricity, and from factories and cars, threatens the environment.

In the south, the forested Sudetes and Carpathian Mountain ranges rim the Czech Republic and cover much of Slovakia. Cereals, root vegetables and livestock are farmed in the valleys. The fertile lowlands of Hungary are scattered with orchards and vineyards. All three countries have vehicle, chemical and textile industries.

The undulating lowlands of the Ukraine with their fertile “black earth” have long been intensively cultivated. There are fields of wheat, barley, sugar beet and sunflowers. Manufacturing is concentrated in the Ukraine’s southeastern cities.

The borders of Central and Eastern Europe have changed many times over the years. Until recently, many countries were controlled by, or were part of the former Soviet Union. They are now independent, and grow in prosperity.

WORLD ATLAS – ITALY

 

Surrounded on three sides by the Mediterranean Sea, Italy is shaped like a boot about to kick a stone – the island of Sicily. The Alps, including the jagged, limestone Dolomites, form the border in the north. Running the length of the boot down to the toe are the thickly-wooded Apennines. Both Sicily and Sardinia are rugged, hilly islands.

Italy also has three active volcanoes: Vesuvius, Stromboli and Etna. In AD 79, Vesuvius erupted, burying the town of Pompeii. The remains of a great Roman civilization have since been uncovered.

Northern Italy is more prosperous than the south, Sicily and Sardinia. There are major industrial cities such as Milan and Turin, vineyards, and fields of wheat, maize and tomatoes.

The Vatican City, which lies within the city of Rome, is the smallest independent state in the world. It is home to the Pope, the head of the Catholic Church.

WORLD ATLAS – SPAIN AND PORTUGAL

The Iberian Peninsula, divided between the countries of Spain and Portugal, is separated from the rest of Europe by the Pyrenees Mountains. The core of the peninsula is a plateau called the Meseta, a landscape of plains crossed by several mountain ranges.

Spain has four official languages – Galician, Catalan, Basque as well as Spanish -and several dialects. The north of the country, Spain’s industrial heartland, is cooler and wetter. Central Spain is much drier. Large areas are barren or given over to rough pasture for sheep and goats. Tourist resorts have grown up along the Mediterranean coast. Andalucía is famous for bull-fighting, sherry, orange trees and flamenco dancers.

Portugal has long held close ties with the sea. Famous for its explorers, Portuguese sailors founded colonies in Africa, Asia and America more than 500 years ago. Today, farming and fishing are among the main industries – supplying the world with anchovies, sardines, shellfish, cork and port, a sweet wine produced in the region near Porto. Along the drier south coast is the Algarve, popular with tourists.

What main factors are threats to environment?

People have made many changes to the world they live in and some of these have had harmful consequences. As the world population increases, there is more need for bigger cities, new towns and farming land. Land has to be cleared, destroying the habitats of many animals and plants. Some of these are now extinct and others are in danger of becoming so. Hunting has also put animals in danger.

There is now nearly three times as much desert in the world as there was 100 years ago. This is partly due to farmers over-grazing their animals on the meagre grass and shrubs and to the clearance of woodland trees for firewood.

Industrialization is a major threat to the environment. Pollution is just one example. Factories discharge harmful chemicals into rivers and seas, killing fish and plants.

The production of chlorofluorocarbons (CFCs) is reckoned to be responsible for damaging the ozone layer, the protective layer in the Earth’s atmosphere that prevents harmful rays from the Sun reaching the surface. CFCs are synthetic chemicals used in aerosol sprays and refrigerators. When they are released into the atmosphere, they destroy the ozone. There is now a hole in the ozone layer above Antarctica.

Air pollution is caused by fumes and smoke from vehicles, factory chimneys and power stations. Poisonous gases, such as sulphur dioxide, mix with rain and mist to produce acids. When the acid rain falls, it kills plants over a wide area. Burning fuels also causes a build-up of carbon dioxide.

Carbon dioxide and CFCs are both greenhouse gases. In the right amounts, greenhouse gases in the atmosphere trap heat from the Sun so the Earth is not too hot or too cold. But if the greenhouse gases build up, too much heat is trapped and the Earth becomes warmer. This change in climate, known as global warming, could have disastrous effects. The ice in the Polar Regions may melt, causing severe flooding to low-lying areas. Changes in the climatic pattern worldwide could lead to violent storms and long droughts.
