Define harmony. :wave:
I think there is a good case to be made that nature lives in harmony, but I would want to redefine the term from its usually understood meaning where everyone and everything are just one big happy family. Except for plants (and that's most plants, not all plants) most everything else on the planet is heterotrophic, meaning they eat or consume things, either things that are already dead, things they have killed, or things that are still living. Plants as well are at war with each other and the things that eat them. Tall plants and vines choke the light off from the understory so other, shorter plants can't compete with them. Many plants secrete toxic chemicals into the soil around them so other plants can't live near them. And lot's of plants are toxic or have some kind of "barb wire defense" to deter feeding. This is not the kind of harmony you might see in a Disney movie.
Yet in the grand scheme of things, we have fairly long periods of evolutionary stasis where organisms over time become supremely (but never perfectly) adapted to their niches, making it very difficult for mutant species to outcompete them. However, throw in an asteroid or volcanic eruption or flood or some other major disturbance and sometimes the playing field changes. Humans, with their incredible ability to affect the planet over vast landscapes, may in fact be destroying our current "harmony." We have had at least 5 major extinctions in the history of our planet and we now appear to be undergoing a 6th major extinction of species. The current rate of species extinction is exponential and therefore warrants our investigation.
