are endangered or even extinct just because humans do varied harm to them.For instance，tigers are being illegally hunted in an incredibly cruel way for their fur while rhinos，for their horns.Besides，we have destroyed their habitats by cutting down trees，throwing away unrecyclable plastic rubbish everywhere and discharging polluted water that contains poisonous chemicals into rivers. It is human activities that are to blame for the mass extinction.However，we should be aware of the fact that without the species on which we depend for our survival，we would be also at risk.Many anxious environmentalists write informative and innovative essays to educate people to adopt a green lifestyle. Conservation measures involve switching to solar energy，stopping using throwaway cartons or chopsticks that can't be recycled，and taking public transportation on a regular basis to and from work.To sum up，everybody has a role to play in protecting our planet and if we all set out to do our part，the harmonious world will be restored. 据说恐龙是由于自然灾害而灭绝的。但是现在，许多物种濒危，甚至灭绝，只是因为人类对它们造成了各种各样的伤害。例如，老虎正在以一种令人难以置信的残酷方式被非法猎杀，为了(得到)它们的皮毛，而犀牛则是为了它们的角。此外，我们砍伐树木，到处扔不可回收的塑料垃圾，把含有有毒化学物质的污水排放到河流中，破坏了它们的栖息地。 人类活动是造成物种大量灭绝的罪魁祸首。然而，我们应该意识到这样一个事实：没有我们赖以生存的物种，我们也将处于危险之中。许多忧心忡忡的环保主义者写了知识性强、创新性的文章来教育人们采用绿色生活方式。节约措施包括改用太阳能，停止使用不能回收的一次性纸箱或筷子，定期乘坐公共交通工具上下班。总而言之，每个人都有责任保护我们的地球，如果我们都开始尽自己的一份力，和谐的世界将会恢复如初。 【知识归纳】　 ◎switch off 关上(电灯、电视等)；断掉(电源) ◎switch on 打开；开始运行 ◎switch (...) from...to...
