格陵兰岛冰川消融，守护地球刻不容缓！
格陵兰岛冰川消融，守护地球刻不容缓！

There is a lot of ice in Greenland. But the ice is melting (融化) now. It melts into water. The water goes into the sea. Then the sea level gets higher.

Why is the ice melting? Our world is getting warmer. When it is warm, ice melts. This is not good for the Earth.

We must help. We can use less energy (能量). We can plant more trees. If we all help, the ice may melt slower. Let’s protect our Earth together.
