 and Kazakh Upland), and a series of mountainous areas, concentrated for the most part in the extreme northeast or extending intermittently along the southern border. The West Siberian Plain, the world's largest, extended east from the Urals to the Yenisey River. Because the terrain and vegetation were uniform in each of the natural zones, the Soviet Union, as a whole, presented an illusion of uniformity.

Nevertheless, the Soviet territory contained all the major vegetation zones with the exception of tropical rain forest. Ten percent of Soviet territory is tundra, that is, a treeless marshy plain. The tundra was the Soviet Union's northernmost zone of snow and ice, stretching from the Finnish border in the west to the Bering Strait in the east and then running south along the Pacific coast to the earthquake and volcanic region of northern Kamchatka Peninsula

. It was the land made famous by herds of wild reindeer, by "white nights" (dusk at midnight, dawn shortly thereafter) in summer, and by days of total darkness in winter. The long harsh winters and lack of sunshine allowed only mosses, lichens, and dwarf willows and shrubs to sprout low above the barren permafrost. Although the great Siberian rivers slowly traversed this zone in reaching the Arctic Ocean, drainage of the numerous lakes, ponds, and swamps was hampered by partial and intermittent thawing. Frost weathering is the most important physical process here, shaping a landscape modified by extensive glaciation in the last ice age

 in Soviet Central Asia, between the taiga and arid zones, occupying a relatively narrow band of plains whose chernozem soils are some of the most fertile on earth. In a country of extremes, the steppe zone, with its moderate temperatures and normally adequate levels of sunshine and moisture, provides the most favorable conditions for human settlement and agriculture. Even here, however, agricultural yields were sometimes adversely affected by unpredictable levels of precipitation and occasional catastrophic droughts.

Below the steppes, and merging at times with them, was the arid zone: the semideserts and deserts of Soviet Central Asia and, particularly, of the Kazakh Republic. Portions of this zone became cotton- and rice-producing regions through intensive irrigation. For various reasons, including sparse settlement and a comparatively mild climate, the arid zone became the most prominent center for Soviet space exploration.
One-quarter of the Soviet Union consisted of mountains or mountainous terrain. With the significant exceptions of the Ural Mountains and the mountains of eastern Siberia, the mountains occupy the southern periphery of the Soviet Union. The Urals, because they have traditionally been considered the natural boundary between Europe and Asia and because they are valuable sources of minerals, were the most famous of the country's nine major ranges. In terms of elevation (comparable to the Appalachians) and vegetation, however, they are far from impressive, and they do not serve as a formidable natural barrier.

Truly alpine terrain was found in the southern mountain ranges. Between the Black and Caspian seas, for example, the Caucasus Mountains

The Soviet Union's water resources were both scarce and abundant. With about 3 million rivers and approximately 4 million inland bodies of water, the Soviet Union held the largest fresh, surface-water resources of any country. Unfortunately, most of these resources (84 percent), as with so much of the Soviet resource base, were at a great distance from consumers; they flowed through sparsely populated territory and into the Arctic and Pacific oceans. In contrast, areas with the highest concentrations of population, and therefore the highest demand for water supplies, tended to have the warmest climates and highest rates of evaporation. The result is barely adequate (or in some cases inadequate) water resources where they are needed most.

Nonetheless, as in many other countries, the earliest settlements sprang up on the rivers, and that is where the majority of the urban population prefers to live. The Volga, Europe's longest river, was by far the Soviet Union's most important commercial waterway. Three of the country's twenty-three cities with more than one million inhabitants were located on its banks: Gorky

The European part of the Soviet Union had extensive, highly developed, and heavily used water resources, among them the key hydrosystems of the Volga, Kama, Dnepr, Dnestr, and Don rivers. As is the case with fuels, however, the greatest water resources are found east of the Urals, deep in Siberia. Of the sixty-three rivers in the Soviet Union longer than 1,000 kilometers, forty are east of the Urals, including the four mighty rivers that drain Siberia as they flow northward to the Arctic Ocean: the Irtysh

, hardy settlers coped with January temperatures that consistently average -50 °C. Transportation routes, including entire railroad lines, had been redirected in winter to traverse rock-solid waterways and lakes.

Howling Arctic winds that produced coastal wind chills as low as -152 °C and the burany, or blinding snowstorms of the steppe, were climatic manifestations of the USSR's close proximity to the North Pole and remoteness from oceans that tended to moderate the climate. A combination of the "Siberian high": cold, high-pressure systems in the east, together with wet, cold cyclonic systems in the west largely determined the overall weather patterns.

The long, cold winter had a profound impact on almost every aspect of life in the Soviet Union. It affected where and how long people live and work and what kinds of crops are grown and where they are grown (no part of the country has a year-round growing season). The length and severity of the winter, along with the sharp fluctuations in the mean summer and winter temperatures, imposed special requirements on many branches of the economy: in regions of permafrost, buildings must be constructed on pilings, and machinery must be made of specially tempered steel

Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron, but various other alloying elements are used, such as manganese, chromium, vanadium, and tungsten...

With most of the land so far removed from the oceans and the moisture they provide, levels of precipitation in the Soviet Union was low to moderate. More than half the country received fewer than forty centimeters of rainfall each year, and most of Soviet Central Asia and northeastern Siberia could count on barely one-half that amount. The wettest parts were found in the small, lush subtropical region of the Caucasus and in the Soviet Far East along the Pacific coast.

Land use and natural resources

The Soviet resource base was by far the world's most extensive, ensuring self-sufficiency for its people in most resources for many years. The Soviet Union was usually first or second in the annual production of most of the world's strategic raw materials. However, most of the topography and climate resembles that of the northernmost portion of the North American continent. The northern forests and the plains to the south find their closest counterparts in the Yukon Territory and in the wide swath of land extending across most of Canada.

Self-sufficiency had traditionally been a powerful stimulus for exploring and developing the country's huge, yet widely dispersed, resource base. It remained a source of national pride that the Soviet Union, alone among the industrialized countries of the world, could claim the ability to satisfy almost all the requirements of its economy using its own natural resources. The abundance of fossil fuels supplied not just the Soviet Union's domestic needs. For many years, an ample surplus was exported to consumers in Eastern Europe

Only occasional and isolated references appeared on such issues as air and water pollution, soil erosion, and wasteful use of natural resources in the 1970s. There were various reasons for not implementing environmental safeguards. In cases where land and industry were state owned and managed, when air and water were polluted, the state was most often the agent of this pollution.

Fourth, advanced means of pollution control and environmental protection can be an expensive, high-technology industry, and even in the mid-1980s many of the Soviet Union's systems to control harmful emissions were inoperable or of foreign manufacture.

's leadership, the official attitude toward the environment changed. Various social and economic factors helped produce this change. To maintain economic growth through the 1980s, a period in which the labor force had been declining significantly, intensive and more prudent use of both natural and human resources was required. At the same time, glasnost' provided an outlet for widespread discussion of environmental issues, and a genuine grass-roots ecological movement arose to champion causes similar to the ecological concerns of the West. Public campaigns were mounted to protect Lake Baykal from industrial pollution and to halt the precipitous decline in the water levels of the Caspian Sea, the Sea of Azov, and, most urgently, the Aral Sea. A grandiose scheme to divert the northern rivers southward had been counted on to replenish these seas, but for both economic and environmental reasons, the project was canceled in 1986.

By 1987 so much water had been siphoned off for irrigation of cotton and rice fields south and east of the sea that all shipping and commercial fishing had ceased. Former seaports, active as late as 1973, were reported to be forty to sixty kilometers from the water's edge. Belatedly recognizing the gravity of the situation for the 3 million inhabitants of the Aral region, government officials declared it an ecological disaster area.

In one of the most publicized cases, the inhabitants of Kirishi, a city not far from Leningrad, succeeded in closing a chemical plant whose toxic emissions were found to be harming—and in some cases killing—the city's residents. Finally, separate, highly publicized cases of man-made disasters, the most prominent of which was the Chernobyl' nuclear power plant accident in 1986, highlighted the fragility of the manproduction -nature relationship in the Soviet Union and forced a reconsideration of traditional attitudes and policies toward industrialization and development.

), in the 1980s concrete steps were taken to strengthen environmental protection and to provide the country with an effective mechanism for implementing policy and ensuring compliance. Two specific indications of this were the inclusion of a new section devoted to environmental protection in the annual statistical yearbook and the establishment of the State Committee for the Protection of Nature (Gosudarstvennyi komitet po okhrane prirody—Goskompriroda) early in 1988.
