问题 How does rotational grazing reduce the need for pesticide treatments? [br]  
Grasslands need time to rest when the cattle and other animals feed on them. Moving animals from one area of pasture to another can provide the time needed for new growth. This is called rotational grazing. Experts say rotational grazing is good for land and animals, and it can save money. This form of grazing can reduce the need for pesticide treatments by reducing the growth of weeds. And it can limit the need for chemical fertilizers by letting the animal waste do the job of natural fertilizer.
India had more than one million camels during the middle of the 1990s. But the population of the animals known for their ability to travel far without much water has fallen sharply. A group in Rajasthan state says India had only six hundred thousand camels by 2005. Rajasthan has traditionally been the area of the country with the most camels. Experts say there are different reasons for the decrease. India’s camels have lost the use of some traditional grasslands and forests because of development and climate change. Courts have barred camels from grazing in national parks. This makes it harder for their owners to feed them.

选项 A、Because they are dying from travelling too far.
B、Because they are short of food.
C、Because they are infected with a disease.
