I agree that you did not explicitly say that it's negative, but the scenario you're referring to obviously has a seriously negative connotation in today's zeitgeist, so you should have been clearer if you wanted to evoke something other than the default connotations. As your comment stands it seems like you're saying "ohnoes humans will be gone!".
I'm not concerned about evoking anything--but it obviously evoked passion in you. That's a good thing to see though, and I'm glad there's people that feel so strongly about humans continuing to exist on the planet for millenia to come! I'm not sure everyone share's your opinion.
I'm sure what you mean by "ohnoes"--I looked it up in a dictionary and couldn't find it--what <i>does</i> it mean?
