Deforestation and unsustainable land-use practices pose a threat to Manipur’s:

The correct answer is: All of the above.

Deforestation and unsustainable land-use practices pose a threat to Manipur’s biodiversity, soil fertility, and watershed protection.

• Biodiversity is the variety of life on Earth. It includes the variety of plants, animals, and microorganisms, as well as the variety of ecosystems in which they live. Deforestation and unsustainable land-use practices can lead to the loss of biodiversity in a number of ways. For example, when forests are cleared, the plants and animals that live in them are lost. In addition, deforestation can lead to soil erosion, which can damage the habitats of other plants and animals.
• Soil fertility is the ability of soil to support plant growth. Deforestation and unsustainable land-use practices can lead to the loss of soil fertility in a number of ways. For example, when forests are cleared, the trees that help to hold the soil in place are lost. This can lead to soil erosion, which can remove the topsoil, the layer of soil that is richest in nutrients. In addition, deforestation can lead to the loss of organic matter in the soil, which is also important for soil fertility.
• Watershed protection is the management of land to protect water resources. Deforestation and unsustainable land-use practices can lead to the loss of watershed protection in a number of ways. For example, when forests are cleared, the trees that help to regulate the flow of water are lost. This can lead to flooding and erosion. In addition, deforestation can lead to the loss of wetlands, which are important for water filtration and storage.

In conclusion, deforestation and unsustainable land-use practices pose a threat to Manipur’s biodiversity, soil fertility, and watershed protection. These practices can lead to the loss of plants and animals, soil erosion, and the loss of water resources.
