The most famous one was the introduction of the rabbit. The rabbits in Australia are mostly from a group of wild rabbits in south eastern Australia. These were released in the hope of starting a business selling rabbits' skin. This did actually happen, but there was nothing to stop the rabbits spreading to the rest of mainland Australia. Now we have billions. They compete with the native animals, damage the vegetation and severely reduce the potential carrying capacity of the land for grasseating animals like sheep and cattle. As well as the disasters caused to the land ecosystem, there have been ones in the water. The most obvious one was the deliberate introduction of European carp(欧洲鲤鱼) to the River Murray. The carp were introduced to eat the weeds growing in the river. Now they have taken over much of the river's ecosystem and severely reduced the number of native fish. Not all destructive introductions in Australia were of foreign species. There are several cases of native Australian animals being taken to different places in Australia and causing destruction. Koalas were introduced to Kangaroo Island and increased to such an extent that they are killing off the Manna Gum trees. 【写作内容】1. 以约 30 个词概括阅读材料的主要内容；2. 由于人类无休止地向大自然索取，无限制地掠夺自然，造成了资源枯竭等。大自然毫不留情地对人类进行了报复。请你以约 120 个词谈谈你对人类和大自然和谐相处的看法，内容包括：(1) 你认为人类为什么要与大自然和谐相处？(2) 举例说明人类与大自然由于不和谐相处而带来的灾害。(3) 在日常生活中，我们应该怎样与大自然和谐相处。【写作要求】...
