The question of whether humans should take responsibility for every species we’ve affected touches on ecology, ethics, and our place in nature. The concept of “invasive species” itself emerged in the 20th century, when global trade and colonization began accelerating the movement of plants and animals across continents. From rabbits in Australia to zebra mussels in North America, these introductions, often unintentional, have reshaped ecosystems and caused immense economic and environmental damage. But many of these species only thrive because humans altered habitats, removed predators, or introduced them in the first place. Should we then intervene to control or even eradicate them, or accept that nature has simply evolved under our influence? The debate questions the moral limits of stewardship: if humanity caused the imbalance, do we have a duty to fix it or is “fixing” itself another form of domination over nature? It forces us to confront whether true responsibility lies in action, restraint, or humility before ecological complexity.
