Are the bird & fish die-offs a new phenomenon? Or is this just the media focusing on something that always happens?

Mainstream news is reporting of mass bird and fish die-offs throughout the world.

Are they reporting on a new and potentially dangerous phenomenon?

Or are they focusing on something that has always occurred?

I remember when mainstream media tried to convince us that shark attacks were on the rise.

Anyone who looked at the statistics that year, however, realized shark attacks were at a rate that was average for the year. The media at the time was hyper-focusing, causing a skewed view of reality to the general public.

I’d like to know if anyone has read any articles or knows any statistics that would put some light on this subject.
