It is mainly caused by human activities and natural factors. Over-farming depletes soil nutrients, while deforestation removes the protection of soil. Besides, climate change leads to more droughts, worsening the situation. The consequences of desertification are severe. It destroys farmland, leaving farmers without a source of income. Many people are forced to leave their homes and become environmental refugees. Moreover, it causes soil erosion and reduces biodiversity. To fight desertification, joint efforts are needed. Governments should make strict laws to protect forests and limit over-farming. Individuals can participate in tree-planting activities and save water. Organizations can raise public awareness through campaigns. Only by working together can we stop desertification and protect our planet. 读后-课堂练习 （一）单项选择 1.Desertification ________ by over-farming and deforestation is a serious threat to the environment.

Every year, millions of hectares of fertile land turn into desert, which threatens food security and people’s lives. Many families are forced to leave their hometowns because of this disaster. As students, we can do our part to fight desertification. First, we can save water in daily life, such as turning off the tap when brushing teeth. Second, we can reduce the use of disposable wooden products to protect forests. Third, we can participate in tree-planting activities on weekends. Besides, we can share environmental knowledge with our families and friends to raise public awareness. Desertification is not an individual problem but a global challenge. Let’s take action now to protect our fertile land and build a greener planet. Together, we can make a difference! Thank you! 1 学科网（北京）股份有限公司 $
