在科学技术发展迅速的今天,我们对自然的或人为的危险和灾难有了比较先进的探测仪器来预防它,然而自然界的一些动物对毒气或瓦斯较为敏感,我们可以称之为“动物哨兵” 很早的时候,法国北方以及英国的威尔士地区的矿工为了防止瓦斯爆炸,就把一只金丝雀带到矿井里。对于一氧化碳,这种鸟比人要敏感80倍。如果它窒息而死,人们就知道有瓦斯爆炸的危险。 在海湾战争中,科威特士兵用这一方法来预防伊拉克军队可能发动的毒气袭击。 Nowadays, with the rapid development of science and technology, we have more advanced detection equipment for natural or man-made dangers and disasters to prevent it. However, some animals in nature are more sensitive to gas or gas. We can call it “Sentinel” Earlier, miners in northern France and the Welsh region of England brought a canary into the mine to prevent a gas explosion. For carbon monoxide, the bird is 80 times more sensitive than humans. If it suffocates, people know the danger of a gas explosion. In the Gulf war, Kuwaiti soldiers used this method to prevent potential gas poisoning by Iraqi forces.
