Ecological Problems of Kazakhstan
Transcript of Ecological Problems of Kazakhstan
Another most urgent problem is the preservation of Aral Sea. Since 1960, the area of Aral Sea has been essentially reducing. Use of water for agricultural crops irrigation has led to reduction by more than 90 % of natural water inflow from Tien-Shan mountains. The sea area has decreased by 2,6 million hectares, the sea has lost 6% of its volume, the water level has decreased by 12 – 24 meters, the concentration of salts has doubled. Daily 200 tons of salt and sand are scattered by wind on distances of up to 300 km. Nowadays, the processes of desertification, salinization of soil, plant and animal life exhaustion, climate change still remain and sickness rate of the population is increasing. The environmental situation of the Aral region has led to impossibility of traditional directions of economic development and has caused a number of social problems.
How it effects to people
The nuclear testing may have ended but it has had long lasting results on the environment and people of Kazakhstan. Many people have developed or inherited cancer caused by radiation and an increased number of children are being born with birth defects. The man in the picture to the right has grown a facial tumor and now has difficulties breathing, seeing, and eating, do to his condition caused by exposure to radioactive material.
The testing site has been closed for some time, but the high levels of radiaion remain present. Nothing can live within the boundries of the acctual site because the levels of radiation are so significant . No living thing can stay for more than a few hours or even minutes depending on how close you are to the center of the site. One villager describes how it is to live there: "The lake is void of any living creature. Fish can't live there. When the wind blows it makes people sick."
Outdoor air pollution is associated with over one million deaths and countless illnesses each year across the globe. We are working to clean up toxic hotspots including major industrial polluters as well as dirty diesel transportation hubs. Our goal is for all children to be able to play outside without fear of asthma attacks or stunted lung growth -- and for all communities to enjoy safe and healthy air quality, eliminating the race and income gaps in access to clean air.
Key issue areas: diesel soot, port pollution, power plants, industrial pollution.
The Soviet Union performed about 500 nuclear bomb tests on a site called Semipalatink-21, that was 160 kilometres away from the Kazakh city of Semipalatinsk which is now Semey. The testing began in1949 and continued for forty more years, ending in 1989. The site was officially closed August 29, 1991. The Soviets built structures and placed animals in the sites to test the strength and affect of the bombs. Two hundred thousand villagers were also subject to the cruelty of the Soviets. The people of Semipalatink were forced to stand outside their homes each time a bomb was tested in order to study the effects of radiation on humans.
We have to protect our health, by helping the environment
