ELI5: What ecological disaster happened on earth in the movie “interstellar “ ? Is it an actual possibility ?

There was a fungal or bacterial blight that was killing off crops. In the movie they mention that it "breathes" nitrogen, or something like that.

They don't really go into detail (nor should they have), but basically all of the food crops.were dying off because of the blight.

It's a possible scenario, but largely improbably.
