What does reforestation aim to achieve?

Reforestation primarily focuses on planting trees in areas where forests have been depleted or destroyed, with the aim of restoring natural forests and their ecosystems. This process is crucial for regenerating forest cover, which provides numerous ecological benefits such as stabilization of soil, improvement of air quality, and restoration of habitats for wildlife.

By reintroducing trees to barren or deforested lands, reforestation can help in restoring the ecological balance that has been disrupted by deforestation or other forms of environmental degradation. The trees planted contribute to the regrowth of forests, which can lead to improved carbon sequestration, enhanced biodiversity, and better soil quality over time, but the immediate and primary goal is to increase tree cover in those specific areas.

The other choices, while they can be related aspects of overall environmental management, do not directly define the primary goal of reforestation. Restoring soil quality and enhancing biodiversity are important ecological benefits that can result from reforestation but are not the main objective. Reducing carbon emissions is a significant global concern, and reforestation helps mitigate emissions as a secondary benefit, but again, it is not the core aim of reforestation itself.
