请听我的评论。一种动物的排名不是根据它的数量是多少,而是根据它下降的速度。在过去的25年里,山地大猩猩的数量下降了60%。很少有其他动物的数量下降这么快。但所有这些动物都是濒危动物,所以所有这些动物都应该被考虑在内
Please listen to this comment. An animal isn't ranked by how little the population is. It's by how fast it's going down. The mountain gorilla population went down 60% in the past 25 years. There are few other animals that have a population going down that quickly. But all these animals are endangered so all should be accounted for.
