The world’s very first mangrove center (红树林中心) was set up in Shenzhen. This center is really important. Its main job is to help China and other countries look after and protect mangroves all over the world.
So, what are mangroves? Well, they are special plants and they grow near river mouths and in wetlands. They are like nature’s bodyguards for the coast. They hold the soil (泥土), and it stops the land from turning into a desert. Also, they do an amazing thing for our earth: They help to slow down global warming.
