Short term, probably. Mid term, we seem to be heading the right way to cleaning up our act before we accidentally kill everything. Long term, highly doubtful; the Earth is going to be destroyed by completely natural occurrences one way or another, eventually. We are the only ones that we know of capable of potentially preventing something like that from happening.
I also believe that sapient beings are inherently more important than a biosphere of non-sapient beings, so even if our existence was flat-out detrimental to the planet, and would continue to be forever, I would still consider our own continued existence more important than the continued existence of the rest of our planet's ecosystem. This is not the case, of course; continued existence isn't a zero-sum game. The best strategy for our survival is ensuring the continued existence and thriving of everything else on our planet.
@Comrade_Silly_Otter"We are an amazing product of Evolution, its greatest success. We have done a large amount of damage but we are getting better. Our technology will get better and will lead us to a better future. We are the result of millions of years of Evolutionary success, act like it." And yet we are the reason the Earth is so messed up. #NoHumansNoProblems
