　　草原上prairie dogs(土拨鼠) 的数量减少，人们就是否应该把其作为保护动物引发了争论。

　　1、农民们觉得土拨鼠是 geological pests，因为它们和cattle竞争食物来源(也就是草地资源)

　　2、Prairie dogs身上有fleas, 会让接触它们的人们感染患病, do harm to human health.

　　3、Prairie dogs do not have enough ecological importance to deserve protection.

　　Listening

　　1、这种想法outdated, 因为现在cattle obtain food by feeding，就是cattle 的食物来源变了，不会受到土拨鼠的影响。

　　2、Prairie dogs身上的fleas在人身上不能存活。 Investigations have shown that in colorado, only 10 people suffered from illness by contacting the prairie dogs in the last 50 years.

　　3、虽然土拨鼠是plant eaters, 但是它们也对草原生态系统有重大影响。例如 burrows made by prairie dogs represent a habitat for other species, 蚂蚁什么 的(这里不太确定)。还有prairie dogs 是它们的predators (例如fox)的食物来源。所以 the decline of the number of prairie dogs exerts a negative impact on prairie ecosystem.
