Kazakhstan faces several important environmental issues. As the site of the former Soviet Union's nuclear testing programs, areas of the nation have been exposed to high levels of nuclear radiation, and there is significant radioactive pollution. The nation also has 30 uranium mines, which add to the problem of uncontrolled release of radioactivity. Kazakhstan has sought international support to convince China to stop testing atomic bombs near its territory, because of the dangerous fallout. Mismanagement of irrigation projects has caused the level of the Aral Sea to drop by 13 m, decreasing its size by 50%. The change in size has changed the climate in the area and revealed 3 million hectares of land that are now subject to erosion. Air pollution in Kazakhstan is another significant environmental problem.

Acid rain damages the environment within the country and also affects neighboring countries. In 1992 Kazakhstan had the world's 14th highest level of industrial carbon dioxide emissions, which totaled 297.9 million metric tons, a per capita level of 17.48 metric tons. In 1996, the total had dropped to 173.8 million metric tons. Pollution from industrial and agricultural sources has also damaged the nation's water supply. UN sources report that, in some cases, contamination of rivers by industrial metals is 160 to 800 times beyond acceptable levels. Pollution of the Caspian Sea is also a problem. Kazakhstan's wildlife is in danger of extinction due to the overall level of pollution.

According to current estimates, some areas of the nation will not be able to sustain any form of wildlife by the year 2015. In the areas where pollution is the most severe, 11 species of mammals and 19 species of birds and insects are already extinct. As of 2001, 15 mammal species, 15 bird species, 5 types of freshwater fish, and 36 species of plant are listed as threatened. Threatened species include the argali, Aral salmon, great bustard, snow leopard, and tiger.

Ecological Problems Chapter 1 Ecology is a very popular word today. But what does it mean? Ecology is a since which studies the relationship between all forms of life on our planet and the environment.

This word came from Greek “oikos” which means home. The idea of home includes our whole planet, its population, Nature, animals, birds, fish, insets and all other living beings and even the atmosphere around our planet. Since ancient times Nature has served Man giving everything he needs: air to breathe, food to eat, water to drink, wood for building and fuel for heating his home. For thousands of years people lived in harmony with the environment and it seemed to them that the resources of nature had no end or limit. With the industrial revolution our negative influence on Nature began to increase. Large cities with thousands of steaming, polluting plants and factories can be found nowadays all over the world.

The by-products of their activity pollute the air we breathe the water we drink the fields where our crops are grown. That’s why those who live in cities prefer spending their days off and their holidays far from the noise of the city, to be closer to nature.

Perhaps they like to breathe fresh air or to swim in clear water because the ecology is not so poor as in the cities. So, pollution is one of the most burning problems of nowadays. Now millions of chimneys, cars, buses, trucks all over the world exhaust fumes and harmful substances into the atmosphere. These poisoned substances pollute everything: air, land, water, birds and animals. So, it is usually hard to breathe in the large cities where there are lots plants.

Everything there is covered with soot and dirt. All these affect harmfully. Every year the atmosphere is polluted by about 1000 tons of industrial dust and other harmful substances. Big cities suffer from smog. Cars with their engine have become the main source of pollution in industrial countries. Vast forests are being cut down for the need of industries in Europe and USA.

The loss of the forests upsets the the oxygen balance of the new wastelands. As the result some species of animals, birds, fish and plants have disappeared and keep disappearing. Water pollution is very serious, too. Ugly rivers of dirty water polluted with factory waste, poisoned fish are all-round us. And polluted air and poisoned water lead to the end of the civilization. So, nowadays a lot of dead lands and lifeless areas have appeared.

Because our actions and dealings can turn the land to a desert. Chapter 2 What is the greenhouse effect, and is it affecting our climate? The greenhouse effect is unquestionably real, and is essential for life on Earth.
