Afforestation and reforestation efforts can help:

Stabilize soil on slopes
Reduce soil erosion
Improve soil fertility
All of the above

The correct answer is: d) All of the above

Afforestation and reforestation efforts can help to stabilize soil on slopes, reduce soil erosion, and improve soil fertility.

  • Stabilize soil on slopes: Trees and other plants help to hold soil in place by their roots. This is especially important on slopes, where soil is more likely to be eroded by wind and water.
  • Reduce soil erosion: Trees and other plants also help to reduce soil erosion by breaking the force of wind and water. This is because their leaves and branches act as a buffer, slowing down the movement of water and wind.
  • Improve soil fertility: Trees and other plants help to improve soil fertility by adding organic matter to the soil. This organic matter helps to improve the water retention and drainage of the soil, as well as the availability of nutrients for plants.

In addition, afforestation and reforestation efforts can also help to improve air quality, provide habitat for wildlife, and mitigate climate change.
