Put 2 February in your diary! It is World Wetlands Day! This special day was first celebrated in 1997
and it is celebrated every year.
The celebration is a call for action. It is a way to show people how important and useful the wetlands
are for humans. On World Wetlands Day, people around the world take part in many wetlands
activities. Children draw pictures to advertise the day. People get together to clean up their local
wetlands.
Wetlands help protect nature and fresh water. In wetlands, there are many small animals such as
lizards, frogs, dragonflies and butterflies. They play an important part in keeping the balance of nature.
All plants and animals are part of the food chain (食物链). If the small, wetland animals die, some other
animals in the food chain will have nothing to eat. They will also die.
People need the wetland to keep the balance of nature in the world. If we don't protect nature today,
it will be gone tomorrow.
