The Aral Sea used to be the fourth largest lake in the world, but now most of it has turned into a desert.
In the past, people used the rivers flowing into the Aral Sea to grow cotton, so the lake water decreased, and the salt and pollution in the lake increased.
Many people got sick because of this, and the environment became very bad.
Uzbekistan is now working together with China to protect the Aral Sea.
China has a lot of experience in preventing desertification and saving water, such as drip irrigation technology.
Drip irrigation can deliver water directly to the roots of plants, which saves a lot of water.
China also brought many salt-tolerant and drought-resistant plant seeds to help improve the land around the Aral Sea.
China and Uzbekistan also plant trees together to reduce sandstorms.
Although restoring the Aral Sea will take a long time, China's help has given people hope.
