When winter comes, cranes migrate（迁徙）from northeast Siberia in Russia to Poyang Lake in Jiangxi Province, China. However, climate change has influenced the birds' living conditions.
In some years, the Poyang Lake experiences floods, while in others, it experiences dry weather.
To help deal with the problem, the local government has planted 70 hectares（公顷）of lotus roots（莲藕）in Nanchang. The birds' population has risen from about 3, 000 to more than 5,000 over the past 20 years.
Over the years, China has worked hard to protect migratory birds. Recently, 1,140 places in the country have been taken as important breeding（繁殖）grounds, wintering grounds and migratory stops. They play a key role in cleaning water, preventing floods, and keeping the balance of the environment.
The law sets rules to help manage wetlands. And it stops harmful activities, including giving out waste water. Thanks to these efforts, China has reported more birds wintering in the wetlands.
A. Most of them are wetlands. B. We need more people to count the birds. C. About 95% of the birds spend winter there. D. It's important for us to do something to protect them. E. In this way, they provide food during the winter for the cranes. F. Both of these lead to the problem that there isn't enough food for cranes. G. To protect wetlands, the Wetlands Protection Law was introduced on June 1, 2022. |
