It falls on February 2nd every year and we welcomed the 29th World Wetlands Day this year, with the theme (主题) Protecting Wetlands for Our Common Future. Wetlands are areas covered with water most of the time. They are really important for a large number of reasons that you might not know before. Wetlands, along with oceans and forests, are known as the three main ecosystems of the earth. There are different types of wetlands. We have got things like rivers, ponds and lakes. And wetlands support many types of wildlife. As a matter of fact, 40% of the world’s plants and animals depend on wetlands. Wetlands act like sponges, taking in water and also carbon dioxide from the air. The plants in wetlands take in climate-changing gases (气体) as they grow. Then when the plants die, they sink (沉入) into mud, catching carbon dioxide instead of letting it all return to the air. This can help to reduce the greenhouse effect. Wetlands also play an important role in the water cycle. They can store lots of water during heavy rainfall, reducing floods in downstream areas. Then the water will flow back into rivers and streams slowly. Unluckily, we have actually lost nearly 90% of the wetlands in the last 100 years, three times faster than forests. Do you know why? It’s things like pollution, climate change and human activities. Wetlands are important to everything, and we need to take action to protect them. ( ) 1. How does the writer lead in the topic? A.
