Attempt This Question
Not attemptedCorrect Answer: (b) It tends to reduce the biodiversity in the area in which it grows.
Prosopis juliflora (now Neltuma juliflora) was introduced into India but has spread aggressively; in areas such as the Banni grasslands it forms dense thickets that out-compete native flora and degrade local biodiversity. Hence it is in the news for reducing biodiversity, making option (b) correct; the plant is not mainly valued for cosmetic extracts or pesticide synthesis.
