What Are Corals?

珊瑚是一种神奇的海洋生物，它们生活在温暖的海水中。你可以把它们想象成海底的建筑师，因为它们建造了美丽的珊瑚礁，就像城市一样。

珊瑚是由小小的动物建造的

Corals Are Built by Tiny Animals

虽然看起来像石头或植物，但珊瑚实际上是由微小的生物组成的，它们叫做"珊瑚虫"。这些珊瑚虫是非常聪明的，它们通过分泌一种坚硬的物质来建造自己的家，就像我们建造房子一样。

Even though they look like rocks or plants, corals are actually made up of tiny creatures called "coral polyps." These coral polyps are really smart, and they build their homes by secreting a hard substance, just like how we build houses.

珊瑚有很多不同的颜色和形状

Corals Come in Many Colors and Shapes

想象一下，海底有像粉红色、蓝色、橙色、黄色等五颜六色的房子，而这些都是珊瑚礁的一部分。有些珊瑚看起来像大海绵，有些像小树枝，有些像脑袋，它们都非常美丽。

Imagine the ocean floor having houses in all kinds of colors like pink, blue, orange, and yellow, and these are all part of coral reefs. Some corals look like big sponges, some like tiny branches, and some even look like brains. They are all very beautiful.

珊瑚礁是海洋生物的家园

Coral Reefs Are Homes for Ocean Creatures

除了美丽，珊瑚礁还有一个非常重要的作用，那就是提供了海洋生物的家园。许多鱼、螃蟹、海星和其他海洋动物都住在珊瑚礁里。所以，可以说珊瑚礁就像是一个大家庭，里面有各种各样的邻居。

Besides being beautiful, coral reefs also have a very important job – they provide homes for many ocean creatures. Lots of fish, crabs, sea stars, and other marine animals live in coral reefs. So, you can think of coral reefs as a big family with all kinds of neighbors.

保护珊瑚的重要性

Why We Need to Protect Corals

我们为什么要保护珊瑚呢？因为它们对我们的地球和海洋生物非常重要。

Why do we need to protect corals? Because they are very important for our Earth and the ocean creatures.

首先，珊瑚帮助维持海洋的生态平衡。它们提供食物和家园，让许多鱼类和其他生物能够生存。

First, corals help keep the ocean's ecosystem balanced. They provide food and homes for many fish and other creatures to live.

其次，珊瑚对抵御风暴和海浪也非常有用。它们就像大海洋的保护墙，保护着海岸线免受风暴的侵害。

Second, corals are also very helpful in protecting against storms and big waves. They act like a protective wall for the coastline, keeping it safe from storms.

但是，不幸的是，一些问题正在威胁珊瑚。气候变化、污染和过度捕捞是珊瑚面临的威胁之一。

However, sadly, there are some problems threatening corals. Climate change, pollution, and overfishing are some of the threats to corals.

气候变化让海水变得更热，这对珊瑚不好，因为它们需要温暖但不太热的海水。

Climate change makes the ocean water hotter, and that's not good for corals because they need warm but not too hot water.

污染也是一个大问题，因为有时候垃圾和化学物质会进入海洋，伤害到珊瑚。

Pollution is also a big problem because sometimes garbage and chemicals can get into the ocean and harm corals.

过度捕捞是指捕捞太多鱼类，这会影响到珊瑚礁的生态平衡。

Overfishing means catching too many fish, and this can affect the balance of the coral reef ecosystem.

所以，我们需要采取措施来保护珊瑚。这意味着要减少使用化学物质，减少捕捞过多的鱼类，还要努力减缓气候变化。

So, we need to take steps to protect corals. That means using fewer chemicals, catching fewer fish, and working to slow down climate change.

我们每个人都可以帮助保护珊瑚。你可以参加海滩清理活动，不乱扔垃圾，还可以节约能源，减少二氧化碳的排放。

Each one of us can help protect corals. You can join beach clean-up events, not litter, and save energy to reduce carbon.
