This is incorrect - see e.g. http://www.bbc.com/earth/story/20150511-why-are-animals-so-b... or https://www.nytimes.com/2019/01/09/magazine/beauty-evolution...
One of the unattractive human attributes is our self-centered arrogance. And unfortunately, combine with our other traits this results in some pretty bad behaviors that have a terrible impact on other species. The question of whether the planet would be better off without humans is not so obviously answered in the negative.
But arrogance lifted to these levels would probably not exist if we weren't here.
The universe doesn't care about us. The universe doesn't care about the things you think are "beautiful". Tomorrow a planet-busting asteroid could collide with the earth and destroy every last bit of life on it (except maybe Tardigrades). The only thing that could possibly ameliorate that is humanity continuing to expand and grow, being a space-faring species, etc. That way some life (and therefore beauty) could be saved when we take those things with us into the stars.
Unless and until we find other intelligent species that are better stewards than us, we're all the universe has got, no matter how shit we are at the job.
Or do you prefer the idea of future environmental dystopia?
If you hate humanity then beauty is pointless, because humans are the only ones who appreciate beauty for beauty, rather than "beauty" just being an evolutionary signal to fuck.
