That time when a guy in Finland made a song about how sad it is that a local animal species is going extinct, the song became a big hit, and it directly led to interest in saving it growing big enough that the species has now recovered and is no longer nearly extinct, merely endangered
The species is the Saimaa ringed seal (Saimaannorppa), and the song in question is Vanhojapoikia viiksekkäitä by Juha Vainio: https://www.youtube.com/watch?v=Zi99Bz_-_No
and what I said is recognized by local scientists as true: this song probably single-handedly saved the Saimaa ringed seal from extinction
