What is one benefit of increased tree planting?

Increased tree planting plays a crucial role in preventing soil erosion. Trees have extensive root systems that help anchor soil in place. This anchoring effect reduces the risk of soil being washed away during heavy rainfall or blown away by wind. Moreover, trees can help to improve soil health by adding organic matter through leaf litter and root decay, further enhancing the soil's structure and fertility. The presence of trees in a landscape promotes a more stable environment, which is essential for agricultural practices and maintaining natural ecosystems.

While the other options suggest negative impacts, such as increasing air pollution or reducing biodiversity, tree planting, on the contrary, is known to improve air quality, enhance humidity through transpiration, and support biodiversity by providing habitats for various species. Therefore, the benefits of tree planting are particularly evident in its role in preventing soil erosion, making ecosystems more resilient and productive.
