"Invasive" are another idea I think are widely misunderstood by the public. I think it is more about how many ecological relationship something has with other species within the local ecosystem. Something without a lot of interactions would just take resources and contribute nothing back to the ecosystem would degrade an ecosystem until there are adaptations to include that species within the ecosystem. Contribution could be food for other species. They might provide habitat. Maybe they help spread seeds, or distribute nutrients for plants. And yes, yields for humans too. By that understanding, I would say that the modern human is probably the most successful invasive specie across many ecosystems. And it isn't that, I am advocating that we get rid of the humans within those ecosystems, but find ways for humans to participate within that local ecosystem. Once those relationships are established, it is better for that local ecosystem to have humans than to not have humans.
