Overgrazing can contribute to:

Reduced biodiversity
Soil erosion
Desertification
All of the above

The correct answer is: D) All of the above

Overgrazing is the excessive use of grazing land by livestock. It can lead to a number of problems, including:

  • Reduced biodiversity: Overgrazing can remove native plants and animals, making it difficult for them to survive. This can lead to a loss of biodiversity in the area.
  • Soil erosion: Overgrazing can remove the topsoil, which is the most fertile layer of soil. This can make it difficult for plants to grow, and can lead to soil erosion.
  • Desertification: Overgrazing can lead to desertification, which is the process of turning land into desert. This is because overgrazing can remove the vegetation that helps to hold the soil in place, and can also lead to a loss of water.

Overgrazing is a serious problem that can have a number of negative consequences. It is important to manage grazing land carefully to prevent overgrazing.
