Everyone tries to get to school on time. But when bad weather causes you problems, can you still make it before the bell rings?
In northern China during spring, big sandstorms often bring problems to students and everyone else. When the sky is dark with sand, buses and cars all move much more slowly.
Sandstorms usually happen in spring. This year, sandstorms started in late March. They have happened in more than 10 provinces in northern China. More than 70 million people have had problems in those places because of the sandstorms.
In northern China, many places have few trees and don't get much rain. People there have been cutting down too many trees. When there aren't many trees, the ground can't keep enough water. Over the years, the ground dries up and turns to sand. When spring comes and the ice melts, the ground becomes looser. Strong winds take the loose sand into the sky, which brings sandstorms.
Sandstorms are bad for people's health. If people breathe too much sand, they may cough a lot. Sandstorms also bring farmers lots of problems. Sometimes their sheep get lost in the storms and never get back home. The winds also break farmers' houses.
What can we do to help stop sandstorms? Here's an idea: ask your parents to help you plant some trees this spring. What's more, if you see people cutting down too many trees, tell them about the danger of sandstorms.
