This is not what 'extinction' means in the all important politicized scientific slum-world of the environmental wackoes. In that feeble twilight world of assholery, "extinction" means that a local population has disappeared--like from a river, say, or a valley. The same animal/plant may be flourishing a few miles away but if they are no longer present in a given locale, then the envrio-nazis will say they are "extinct."
This, btw, is the language and definition of extinction used by the Endangered Species Act (ESA,) and is the reason these whorehouse versions of scientists get away with such lies.
You can look it up.
So, basically, if I don't have anymore beer in my fridge, my beer isn't extinct, I'm just too lazy to get more?
Besides, I can’t take supposedly educated people who use the phrase “go extinct” anyway. The proper phrase is “become extinct”. So, as long as they can’t speak properly how can I imagine they actually have an education? Idiots.
Ironically, these are the same people who buy into Darwin and survival of the fittest.
