* C U R B O N C 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.

слайд № 6

* A I R P O L LU T I O N 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. Smoke Billowing from Industrial Smokestacks

слайд № 7

* Pollution from Automobile Traffic Automobile exhaust contains a number 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.

слайд № 8

* RESULTS OF AIR POLLUTION Thermal Inversion (тепловые аномалии) Smog (туман) surrounds 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.

слайд № 9

* Greenhouse Effect Global Warming, an increase in the earth's temperature due to the use of fossil fuels and other industrial processes leading to a buildup of “greenhouse gases”

слайд № 10

* Ozone Destruction In the 1970s and 1980s, 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

слайд № 11

* Acid Rain, form of air pollution Forest Damaged by 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.

слайд № 12

* W A T E R P O L L U T I O N 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.

слайд № 13

* WATER POLLUTION Exxon Valdez Oil Spill Cleanup Workers washed 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.

слайд № 14

* Oil Spill Clean-up Workers use special nets to clean 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.

* Demonstrators Protest Drilling Drilling – бурение скважин

слайд № 16

* Toxic Waste in Love Canal Residents of the Love Canal area in Niagara Falls were forced to evacuate when hazardous (опасные) wastes leaking from a former disposal site threatened their health and homes in the late 1970s.

слайд № 17

* ANNUAL HOUSHOLD WASTE !!!

слайд № 18

* An average city dweller may produce a ton 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.

слайд № 21

* R E C Y C L I N G Recycling Aluminum Cans In an effort to conserve nonrenewable natural resources, many industries and individuals recycle waste aluminum. At this collection point, the Alcoa Recycling Company in New Jersey processes aluminum cans into large bales.

слайд № 22

* Composting and Organic Waste Waste from the garden, yard, and table does not have to be thrown away. It may be condensed and reused as a fertilizer through a process called composting. The compost is then applied to plants as a fertilizer.

слайд № 23

* Plant Generates Energy from Garbage Garbage is converted to useful energy in this solid waste plant. (отбросы)

слайд № 24

* QUESTIONS FOR DISCUSSION What can cause air pollution? What does acid rain harm? Where do some companies dump their chemical waste? What kinds of energy are renewable? What is an “ energy leak” and what are the ways of solving this problem? Why do farmers spray chemicals on crops? Why do you think recycling programs are important? Is there a lot of trash in your village? What noble work do the people of “Greenpeace” do? Why must technology bring apology to ecology? What do you think you should do to protect the environment? MAKE A POSTER CALLING TO PROTECT THE ENVIRONMENT.
