In fact, I've got many plants and animals. I'm saltier than any sea, so people can lie on my surface. Rivers flow into me. But now people take too much water from them. My water level is going down. I am becoming smaller year by year. Take less water, or I dry up within the next 100 years. Then I really will be dead! 1. What is the Dead Sea actually? A. A real sea with plenty of fish B.

A. It is getting bigger and bigger every year B. Its water level is dropping because of water loss C. There are no plants or animals living in it D. It is going to become the saltiest sea soon 4.

However, people are cutting down my trees for wood and to make space for farming. Please stop it. I'm disappearing. Besides, the rain forest can also help control the climate. It absorbs a large amount of carbon dioxide and produces oxygen. Without it, the local temperature will rise and the weather will become more extreme. But now, less and less of the forest is left. 6.

Two hundred years ago, there were about 150 glaciers. But now, there are around 25. Please stop climate change. I'm turning into Waterworld! The melting glaciers not only make the park less beautiful, but also cause rising sea levels. Many coastal cities may be under water in the future.

The mountains shine brightly under the sun, like white lotus flowers. The lovely blue of the sky always gives me a calm feeling. It is like a great sea above the plateau. And words can't express my love for the rivers and lakes. There are a hundred kinds of blue in the water. Our grasslands, forests and fields are all green. That's my favourite colour. It means hope because it is the colour of life. But green is not just the colour of nature now. Trains are running through the plateau. They are this beautiful colour, too. The plateau is quieter than the big cities. We have fewer shops and restaurants. But we have the best presents from nature. In my heart, it's better than any other place.
