Questions: Os processos de degradação dos solos não são exclusivos de países pobres e vem sendo agravados nos últimos anos com o avanço a agropecuária e com a expansão urbana. No Brasil, a população colabora de modo intensivo para a destruição do solo, quando: planta árvores semeia trigo e cereais semelhantes. derruba florestas. irriga suas plantações.

The answer is derruba florestas.

Planting trees generally helps in soil conservation and prevents soil degradation. Trees stabilize the soil with their roots, reduce erosion, and improve soil fertility.

Sowing wheat and similar cereals can lead to soil degradation if not managed properly, but it is not the most intensive way the population contributes to soil destruction.

Deforestation is a major cause of soil degradation. When forests are cleared, the soil loses its protective cover, leading to increased erosion, loss of nutrients, and disruption of the soil structure. This is a significant issue in Brazil, where large areas of the Amazon rainforest are being cleared for agriculture and urban development.

Irrigation can lead to soil degradation if not managed properly, such as through salinization or waterlogging. However, it is not as directly destructive as deforestation.
