"Crying wolf is a real danger"

In this quote, David Attenborough is alerting us about the repercussions of incorrectly raising alarm or producing unneeded panic. The expression "crying wolf" describes the famous myth where a shepherd young boy repeatedly sobs for aid, declaring that a wolf is attacking his flock, even though there is no wolf. Ultimately, when a genuine wolf does appear, no one believes the young boy's weeps for assistance and the wolf winds up devouring the sheep. Attenborough is warning us that if we constantly exaggerate or fabricate risks, people will become desensitized and not take real dangers seriously. This can have severe effects, specifically in the face of real ecological or social crises. For that reason, it is very important to be genuine and responsible in our actions and words, and not to produce unneeded fear or panic.
