[10建議措施段]Indeed, the earth is our home and we have the duty to take care of it for ourselves and for our descendants.

　　[2./圖表描述段]As is shown in the picture, we can see clearly the relation ship between people and desert. In the left hand picture, people are fleeing from greedy sand hills because they cut down all the trees. The caption reads, As the sand advances, we retreat. In the right hand picture, the people have returned carrying tools, water, and young trees to plant the land again. The caption reads: As we advance, the sand retreats.

　　[5.意義闡述段]It seems to me that the cartoonist is sending a message about the importance of trees in water and soil conservation and the need for everyone to fight against the danger of the desertification.
