Changes to one part of a region often lead to other changes. Here areThe marine environment became hostile to the sea life in it, killing the some of the results of the shrinking of the Aral Sea:plants and animals. As the marine life died, the fishing industry suffered. • As water has been drained from the rivers for cotton farming, the seas water has become much saltier.
  • 3. 3 DrY Tears• As more water has been taken from the rivers, the seas water level has decreased by over 60%.• Drinking water supplies have dwindled, and the water is contaminated with pesticides and other agricultural chemicals as well as bacteria and viruses.• The farms in the area use some highly toxic pesticides and other harm- ful chemicals. For decades, these chemicals have been deposited into the Aral Sea. When the wind blows across the dried-up sea, it carries dust containing these toxic chemicals.• Lakes and seas tend to have a moderating effect on the climate. In other words, the land right next to a body of water tends to be warmer in the winter and cooler in the summer than land thats not near the water. As the Aral Sea has lost water, the climate has become more extreme.So a centuries old way of life has disappeared in decades. The vast areaof exposed seabed is laced with pesticides, so when the wind blows, duststorms spread salt and toxic substances over hundreds, if not thousandsof kilometres. Its estimated that 75 million tons of toxic dust and saltsare spread across Central Asia each year. If the Aral Sea dries up comple-tely, 15 billion tons of salt will be left behind.Muynak is 210 km (130 mi) north of Nukus. Tourists can take a taxi or abus to reach Muynak from Nukus. There are options for private accom-modations in Muynak where you can stay overnight.

There will probably be a full report on our photo expedition to the Aral Sea later on. But in the mean- time I would like to say little bit about our team, our route and the jour- ney itself. This note draws a line, so to speak, under my six previous series of photos with commentaries. I loved the idea of going to Uzbekistan at once. As always, everything happened spontaneously and very quickly. A classic beginning - there I was, sitting at home, not planning to go anywhere. But then I came across the plan of the route which Jahangir aka had worked out on " Friends Lent " and I was immediately hooked. I spent a few days trying to work out how I could get away, and then a day after that I already had the "Uzbek airlines" tickets in my pocket.
