The point about technology is that there is no choice. It's not like if we did nothing, everything would just live happily ever after. Every species on this planet is living on borrowed time. Literally the only choice for the persistence is advancement and expansion, which of course will also cause numerous negative effects along its course. Also, the first [1] (and one of the most extreme) extinction events ever was indeed caused by a single species, cyanobacteria. Prior to the evolutionary development of photosynthesis, there was plentiful simple life on the planet. The evolutionary emergence of photosynthesis resulted in a dramatic and rapid introduction of oxygen into Earth's atmosphere which was exceptionally toxic to the existing abiotic species. We only think of oxygen as a good thing, because we evolved in its presence. If there was an advanced species that managed to evolve in abiotic circumstance, we'd probably look as weird to them as a creature that breathes gaseous arsenic would look to us!
