42To help deal with the problem, the local government has planted 70 hectares of lotus roots(莲藕)in Nanchang.
43 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.
44 They play a key role in cleaning water, preventing floods, and keeping the balance of the environment.
