Why would it not be? You don't think the earth and its surviving species would be better off without a species unnaturally filling its air, water, and ground with poison? Our trash, our carbon, and our chemicals? The nuclear waste byproducts that take thousands or millions of years to degrade? The species that die needlessly, not because they are in our food chain but rather they are in the way of our runoff? Not to mention the forests we destroy, the habitats we waste. I'm simply agreeing we are a plague. The species of earth would be better off without us. It's only a matter of time.
Everything you said is part of the natural order of things. You are stupidly thinking we are not part of nature. Everything we do is natural, if it was not, then we would not be able to do. It is the natural order for species to either adapt to the changing landscape or die off. That is how things have worked since life has existed.
I find that you are hypocritical in saying that we are meaningless to the grand scheme of things and yet put such importance to other equally meaningless things. The Earth and the Universe do not need animals are forests, just like you said, it will keep on going without those things.
