Prosopis juliflora Invasive Species
Question
Why is a plant called Prosopis juliflora often mentioned in news?
Options
Its extract is widely used in cosmetics
It tends to reduce the biodiversity in the area in which it grows
Its extract is used in the synthesis of pesticides
None of the above
Explanation
Prosopis juliflora, commonly known as mesquite or vilayati babul, is frequently mentioned in environmental news because it is an invasive species that poses a significant threat to biodiversity. Originally introduced to India from Central America for afforestation and fodder, it has spread rapidly and aggressively in many parts of India, particularly in arid and semi-arid regions. It reduces biodiversity by outcompeting native vegetation, forming dense thickets that native species cannot penetrate, and depleting soil moisture. The plant is highly invasive and difficult to control, making it a conservation concern. Options A and C are incorrect as these are not the primary reasons Prosopis juliflora is discussed in news. It is not widely known for cosmetic or pesticide applications. The ecological threat it poses to native biodiversity is the main reason for media coverage.
