I gave you that information, I said “from 1 to 2” and added context of “a tree” (singular)
My terribly made point is that although technically correct when talking about relative increase it’s dumb as fuck to say trees “surged in population” after adding just one more on one street. It’s a drop on the ocean.
I feel like the term surge respects the final total relative to what its maximum could be as well as the relative increase. But obviously language is regional and up for interpretation
