# The caribou go extinct

Pleas! If I said "The caribou go extinct", does that mean that the caribou are in the process of extinction (i.e. they are about to be extinct due to their low numbers), or that the caribou have already been extinct? And more generally, is that expression (go+adjective) for the past, present, or the near future?

It's the sort of sentence you'd expect to hear in a historical narrative, describing each event as it happens. The Ice Age starts to end. A new species of wolf starts to evolve. The caribou go extinct.

You might like to see this previous thread:
go extinct / become extinct
It doesn't answer my question. my question is: does the expression give the meaning of the present or the past?

For instance if you say "You got to do the dishes", you use the expression in the past form with the meaning of the present. So that, whoever hears this sentence, will go to do dishes.

I hope I could explain myself well...

There is no narrative context. It is a calculus question, and I need to represent the statement "The caribou go extinct" mathematically. So, I need to understand: when I hear that expression, should I expect that there are caribou (but with small numbers) or there are not???
