Secondly, a massive group of volunteers could have success trapping and destroying toads. But its likely that these untrained volunteers would inadvertently destroy many of Australias native frogs some of which are endangered. Its not always easy to tell the cane toad apart from native frogs especially when its young.
第二,人数众多的志愿者队伍的确可以抓住和消灭蔗蜍。但是这些没有经过训练的志愿者很可能会无意间杀死很多澳大利亚原产的青蛙,而其中的一些已经是濒危物种的。蔗蜍和澳大利亚原产青蛙并不容易区分,尤其是在它们都是幼体的时候。
Third, using the virus is a bad idea because it could have terrible consequences for cane toads in their original habitat in Central and South America. You might be wondering how can virus released in Australia cause harm in the Americas. Well, Australian reptiles and amphibians are often transported to other continents by researchers or pet collectors for example. Once the animals infected by the virus reach Central and South American, the virus will attack the native cane toads and devastate their populations. That would be an ecological disaster because in the Americans cane toads are a native species and a vital part of the ecosystem. So if they are eliminated the whole ecosystem will suffer.
第三,病毒可能会对蔗蜍原产的中南美洲的生态环境造成严重的破坏,所以使用病毒也是一个坏主意。你们可能很好奇为什么投放在澳大利亚的病毒会破换美洲的环境。恩,研究者或者宠物饲养者常常会被澳大利亚的爬行动物和两栖类动物带到其他的大洲。一旦感染此病毒的动物被带到了中南美洲,那么这种病毒就会感染当地的蔗蜍,使得其数量锐减。因为蔗蜍在美洲是原生物种,是生态系统的重要组成部分,所以其数量锐减将会是生态灾难。所以,如果蔗蜍灭绝了,那么美洲的生态系统也会受到破坏。
