Design a slogan about reducing desertification area

Either the desert conquers mankind, or mankind conquers the desert.

Either the desert conquers mankind, or mankind conquers the desert. This sentence highlights the importance of reducing desertification. Under the sandy surface conditions of extreme arid, arid and semi-arid and some semi-humid areas, due to the influence of natural factors or human activities, the balance of the natural and fragile ecosystem is destroyed, and wind and sand activities are the main symbol, and gradually form The land degradation process of wind erosion and aeolian landform structure landscape.

Extended information:

Arid land accounts for 40% of the world, of which 70% of the land in Africa is desert and arid land. Although there are rainforests in Latin America and the Caribbean, 1 /4The land is desertified or arid land. 400 million people in Asia live in deserts or arid lands, and the area of ??arid lands is increasing by about 2,500 square kilometers every year. Of course, dry land does not mean barren land. ?

Human production, life, war and other activities have long affected the natural desertification process. For example, overgrazing beyond the carrying capacity leads to vegetation loss and soil erosion, which is difficult to recover. About half of the world's cattle, 1/3 of sheep, and 2/3 of goats graze in arid areas; overcropping leads to nutrient loss and soil erosion. .

Excessive irrigation causes water to evaporate, leaving salt in the soil. The resulting salinized land is also classified as degraded land. Globally irrigated arable land accounts for 17% of the total arable land and contributes 40% of the world's food production. However, partly due to flooding and salinization, crop yields have been reduced, leading to the degradation of about 2 million hectares of land.
