Farmland shortage I think farmland shortage is the worst, because we need farmland to grow food for people. Without enough farmland, we will not have enough food to eat, and food is necessary for everyone’s life. Sandstorms I think sandstorms are the worst, because they bring strong dirty wind. They pollute the air, hurt our health and also destroy our houses and crops. People cannot live comfortably with such bad weather.
