lake：是指陆地上相对封闭的大片水域，通常由地壳运动、冰川作用、火山活动等自然因素形成，也有一些是人工修建的水库形成的湖泊。通常呈不规则的圆形或椭圆形等，边界相对清晰，有固定的水域范围。

Natural wonders crying aloud for help
The Dead Sea could die!
I’m not a sea but a lake. And I’m not dead. 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’ll dry up within the next 100 years. Then I really will be dead!
Rainforest - forest ≠ rain
I’m the rainforest of Madagascar. As my name suggests, I make rain for my plants and animals, such as monkeys, snakes and many kinds of flowers. For 80% of them, I’m their only home in the world. However, people are cutting down my trees for wood and to make space for farming. Please stop it. I’m disappearing.
If Frozen turns into Waterworld ...
I’m a glacier at the Glacier National Park in America. It’s a land full of ice and snow. Do you want to explore the white world in the film Frozen Then my home is the best choice. Two hundred years ago, there were about 150 glaciers. But now, there are around 25. Please stop climate change. I’m turning into Waterworld.
