If a pasture is grazed continuously, what problem could arise for pastoral communities?

Correct answer: Grass could get less chance to regrow

The direct answer is A: continuous grazing can leave grass with too little time to regrow. A pasture is not an unlimited food store. When animals repeatedly eat plants before they recover, roots and soil can weaken, plant cover can decrease, and erosion may increase. The reasoning is: continuous use removes grass; less grass means less food; less food harms animal health and productivity; therefore pastoralists need seasonal movement or planned resting of grazing areas. Option A correctly describes this ecological problem. Option B is impossible because grass does not turn into gold. Option C is unrelated and opposite to the likely result: overgrazing does not automatically create more water. Option D is also unrelated; heavy grazing does not make travel routes easier. Seasonal movement helped distribute grazing pressure and allowed pastures to recover. Memory cue: pasture also needs rest.
