Final answer:
Residents in Aralsk have adapted to the shrinking Aral Sea by benefiting from Kazakhstan's government efforts in reviving the northern portion while facing environmental and health challenges in other areas, with Uzbekistan exploring oil in the south.
Step-by-step explanation:
Citizens in Aralsk have had to adapt to the significant environmental changes resulting from the shrinking of the Aral Sea. The devastating decline in the sea size has had drastic effects on the local economy, particularly the fishing industry which had employed a substantial number of people. In response, there have been efforts to revive the sea, especially in the northern part known as the Little Aral Sea.
Kazakhstan's government has constructed a major dam and updated canal systems to help rejuvenate the northern section of the sea. This has led to the water level rising and a reduction in salinity, thereby reviving the fish population and bringing new life to the fishing industry.
In contrast, the southern portion has seen no relief and Uzbekistan has turned to exploiting the region for oil as the sea continues to shrink and the environmental impacts worsen, including health issues like cancer and respiratory illnesses in local populations caused by dust storms carrying chemicals and salt from the dry seabed.
