Put 2 February in your diary! It is World Wetlands Day! It marks the date that the

Convention(公約) on Wetlands was signed(簽署)in1971.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 people. On World Wetlands Day, people around the world take

part in many wetlands activities. People take trips to the local wetlands. There are talks

about how important the wetlands are. People get together to clean up their local wetlands

Children draw pictures to advertise the day. People also compete(比賽)in boat races.

　 The World Wetlands Day is important! If there are no wetlands, there will be no water for anyone in the future. Wetlands help protect nature and resources(資源)like fresh water. Already, more than 10000 million people in the world do not have fresh water.

　 Many people do not know how important the wetlands are. They can understand why an

elephant or a tiger is important because they are big, beautiful animals. It is much harder for

them to understand how important the animals in the wetlands are. These small animals,

such as frogs and snails, play a very important part in keeping the balance of nature.

　 All plants and animals are part of the food chain(鏈).If the small wetlands animals

today，it will be gone tomorrow.

Once when I was a teenager, my father and I were standing in line to buy tickets for the circus. Finally, there was only one family between the ticket office and us. This family made a big impression on me.

       There were eight children, all probably under the age of 12. You could tell they didn’t have a lot of money. Their clothes were not expensive, but they were clean. The children talked excitedly about the clowns. It was clearly a very important day out for them. The father and mother seemed happy as they could be.

       The tickets lady asked how many tickets the father wanted, he proudly answered, “Please let me buy eight children’s tickets and two adults’ tickets, so I can take my family to the circus.”

       The ticket lady told him the price.

       The man’s wife lowered her head. There was no longer a smile on the man’s face. He quietly asked, “How much did you say?”

       The ticket lady again told him the price.

       The man obviously didn’t have enough money. But how could he tell his kids the bad news?

       Seeing what was happening, my dad took a $20 note from his pocket and dropped in on the ground. (We were not rich ourselves at all!) He then tapped the man on the shoulder and said, “Excuse me, sir, you dropped this.”

       The man understood my father was helping him. He picked up the money, looked straight into my dad’s eyes, and in tears replied. “Thank you. This really means a lot to me and my family.”

       Although we did not go to the circus that night, we didn’t go without.
