It's a terrible picture almost everywhere you look.
The Antarctic krill population is facing a similar decline due to influencer marketing (promoting Krill as a superior omega 3 supplement). Sardines and Krill are the foundation of the entire oceanic food ecosystems. This is not good.

As terrible as the influencer scourge is for society, I somehow doubt that it was a 3 day social media fad a couple of weeks or months ago caused the collapse of ocean wildlife.
