alt Hacker NewsHumans are the only species I know of that goes out of its way to eradicate other species they find annoying, particularly without understanding said species' role in the ecosystem. And we're definitely the only species that has an economic system that rewards superorganisms that accidentally poison the entire ecosystem and then lie about it.
If you watch something like "Life on our planet", there have been species that basically hunted the seas empty of their food sources and then died out, so we're not that unique in that respect, but we are extremely efficient about it.
