As a result, farmers have lost millions of dollars worth of crops annually. Yet even if elephant sanctuaries were created on a widespread basis to guarantee elephants sufficient natural vegetation, the raiding would likely persist, since____
在亚洲和非洲人破坏了很多大象吃的自然生长的植物,迫使大象去破坏种植地,农民每年损失几百万农作物,即使保证大象足够的自然植物,这个掠夺也会持续存在

(C) some of the land where crops have suffered extensive damage from elephants has been allowed to return to its natural state.
(D) elephants tend to prefer cultivated crops to wild vegetation as a food source. 大象更喜欢种植的农作物,那就解释了即使给足够的自然植被,还是会破坏农作物的原因
(E) elephant sanctuaries are usually created in areas that are rich in the natural vegetation on which elephants have historically depended.
