近日,美国生态学者通过研究认为,持续不断的气候变化以及人类对土地的使用会导致很多鸟儿濒临灭绝,甚至受威胁程度较低的犀鸟也在此之列。这个论断也许有点危言耸听,不过这确实应该引起人类的警醒,除了要认真研究气候变化,也要注意保护生态环境,保护鸟儿的家园,我们不敢想象没有鸟儿的世界会变成什么样子。 Recently, American ecologists believe that continuous climate change and the use of land by humans will lead to the extinction of many birds, including even less threatening hornbills. This assertion may be somewhat alarmist, but it should really arouse the vigilance of human beings. Apart from studying climate change seriously, we must also pay attention to protecting the ecological environment and protecting the homeland of the birds. We dare not imagine what the world without birds will look like.
