What one food source is the single most important item to its region? And think the entire ecosystem.
For example- the date palm in the middle east, or pacific salmon, etc.
Just curious. There is no right answer-well, there may be a ‘right’ answer, but I don’t know what it is.
*** Update ***
I don’t mean what is most important to humans. I mean the regional ecosystem. If there were no more slamon, humans would get by, but it would devastate certain ecosystems. Same with date palms. Things like that are what I meant.
