Quote:

India "produces 85% of the world's supply of guar"--"which means 'cow's food' in Hindi [and Urdu; Pakistan has two official languages: Urdu and English]. Rajasthan's semiarid climate makes it one of India's poorest states but also a perfect place to cultivate guar beans, which grow in pods on a low-lying plant.
