Which of the following does NOT contribute much to the degradation of the Thar Desert ecosystem?

Correct option is D

The correct answer is (D) Increased plantation of native trees

Explanation:

• Increased plantation of native trees does not contribute much to the degradation of the Thar Desert ecosystem. In fact, it can help stabilize the ecosystem by providing soil protection, reducing erosion, and enhancing biodiversity.
• Native trees help maintain soil fertility and support local wildlife, which is crucial for the sustainability of the desert ecosystem.

Information Booster:

• The Thar Desert is prone to erosion and degradation due to factors such as erratic rainfall, grazing by livestock, and climate change, which directly affect its fragile ecosystem.
• Native trees planted responsibly help in conserving soil moisture and preventing the spread of desertification, making their plantation a positive influence on the ecosystem.

Additional Knowledge:

• Option A: Climate change: Contributes significantly to the degradation of the Thar Desert ecosystem by altering rainfall patterns, increasing temperature, and causing more frequent droughts.
• Option B: Erratic rainfall: Erratic rainfall leads to water scarcity and soil degradation, which are key drivers of desertification in the Thar region.
• Option C: Grazing by livestock: Overgrazing by livestock leads to the destruction of vegetation, which accelerates soil erosion and contributes to desertification in the Thar Desert.
