Y C L E
Carbon (углерод), used by all living

organisms, continuously circulates in the earth’s ecosystem. In the atmosphere, it exists as colorless, odorless carbon dioxide (углекислый газ)gas, which is used by plants in the process of photosynthesis. Animals acquire the carbon stored in plant tissue when they eat and exhale carbon dioxide as a by-product of metabolism. Although some carbon is removed from circulation temporarily as coal, petroleum, fossil fuels, gas, and limestone deposits, respiration and photosynthesis balance to keep the amount of atmospheric carbon relatively stable. Industrialization, however, has contributed additional carbon dioxide to the environment.

Carbon dioxide, sulfur dioxide, and

other types of contaminants pouring from industrial smokestacks contribute to worldwide atmospheric pollution.
Carbon dioxide contributes significantly to global warming, while sulfur dioxide is the principal cause of acid rain.
Other environmental problems stemming from smokestack emissions include respiratory diseases, poisoned lakes and streams, and damaged forests and crops.

Pollution from Automobile Traffic Automobile exhaust contains a number of airborne

of airborne pollutants that adversely affect the health of

animals and plants and the chemical nature of the atmosphere. Carbon dioxide and hydrocarbon emissions, two of the major components of automobile exhaust, contribute significantly to global warming and are produced as a by-product of the combustion of petroleum-based fuels. Elevated carbon dioxide and hydrocarbon levels cause sunlight to be reflected and trapped within the atmosphere, which slowly raises the temperature of the atmosphere.

RESULTS OF AIR POLLUTIONThermal Inversion(тепловые аномалии)	Smog (туман) surrounds the Angel Monument

the Angel Monument in Mexico City, Mexico, during a

thermal inversion. Air pollution increases dramatically as a mass of cold air is trapped below a warmer mass of air. The absence of wind circulation prevents pollution near the earth’s surface from escaping.

scientists began to find that human activity was having

a detrimental effect on the global ozone layer, a region of the atmosphere that shields the earth from the sun's harmful ultraviolet rays. Without this gaseous layer, which is about 40 km (about 25 mi) thick, no life could survive on the planet

Acid Rain

Forests, lakes, ponds, and other terrestrial and aquatic

environments throughout the world are being severely damaged by the effects of acid rain. Acid rain is caused by the combination of sulfur dioxide and nitrogen compounds with water in the atmosphere. In addition to chemically burning the leaves of plants, acid rain poisons lake water, killing most, if not all, the aquatic inhabitants.

Acid rain is

a major global problem. Acid rain corrodes metals, weathers stone buildings and monuments, injures and kills vegetation, and acidifies lakes, streams, and soils, especially in the poorly buffered regions of northeastern North America and northern Europe .
It is estimated that each year 10 million people die worldwide from drinking contaminated water.

Polluted River In The United Kingdom
The pollution of rivers and streams with chemical contaminants has become one of the most critical environmental problems of the 20th century.

WATER POLLUTIONExxon Valdez Oil Spill Cleanup	Workers washed the shoreline on Latouche

the shoreline on Latouche Island, Alaska after the Exxon

Valdez oil tanker ran aground in 1989, dumping more than 380 million liters (10 million gallons) of oil into Prince William Sound. The resulting environmental damage prompted the United States Congress to pass federal safety requirements for oil tankers and barges and to assign the principal cost of spill cleanup to oil companies.

Oil Spill Clean-upWorkers use special nets to clean up a California

up a California beach following an oil tanker spill.

Tanker spills are an increasing environmental problem because once oil has spilled, it is virtually impossible to completely remove or contain it. Even small amounts spread rapidly across large areas of water.

An average city dweller may produce a ton of refuse in

of refuse in a year, a volume that rapidly

overflows local dumps. Cities running out of space for landfill often turn to incinerating their waste or transporting it to other areas, although up to 90 percent of the material might have been recycled.

It may be condensed and reused as a fertilizer through a process called composting. The compost is then applied to plants as a fertilizer.
