Unit 5 Into the wild Developing ideas 濒危动物素材课件-2023-2024学年高一上学期英语外研版（2019）必修第一册

野生动物保护素材 Native to (原产于) parts of Southeast Asia, Siamese crocodiles are critically endangered(濒危的) and have become virtually extinct(灭绝的) in the wild. Due to hunting(猎杀) as well as habitat loss(栖息地的丢失), they are now absent from(缺少) nearly 99% of their original(原来的) range. A huge part of the decline(减少) of population is due to humans using their wetland habitat for rice farming, and things only took a turn for the worse (情况变得糟糕)when large-scale hunting for their skin(皮肤) for commercial purposes(商业目的) began in the 1950s. Ultimately(最终), scientists add that without a serious reduction(减少) in greenhouse gas, 99 percent of the world's coral reefs will be gone by(消逝go by) the end of the century. There is a limit(限度，限制) to how quickly corals can adapt(适应) warm climate(气候), but if temperatures(温度) rise rapidly, then extinction(灭绝) is certain. The wolverine(狼獾), a native species to the northern forests, is currently endangered due to habitat loss and overhunting. With their original habitats being destroyed, these creatures are slowly becoming extinct. The use of their skin for commercial purposes also adds to their endangerment. It is crucial to preserve the natural habitats of the wolverine and other native species to ensure their survival. Ultimately, we need to limit greenhouse gas emissions to curb climate change and the rise in temperatures. Failure to adapt to these changes could lead to extinction for many species. Siamese crocodiles, which are native to areas of Southeast Asia, are very endangered and have almost completely disappeared from the wild. They are extinct in over 99% of their previous range because to habitat loss and illegal hunting. Humans' use of their wetland habitat for rice farming is largely to blame for the population reduction, and things only became worse when large-scale commercial skin hunting for Siamese crocodiles started in the 1950s. Scientists conclude that by the end of the century, 99 percent
