> For one thing, preserving the purity of a local ecosystem is not the same thing as preserving the purity of your local human race, but it's not entirely different either. It is entirely different. We are all the same species. Race is a social construct, and unlike foreign species introduction, the introduction of a wider genetic or cultural pool does not cause an ecosystem collapse. > Also, the idea that new species "destroy" ecosystems is really flawed. What they do is change ecosystems. With a new species, an area finds a new balance after a while, and life goes on This is just optics. You could say nuking a city just “changes” it into a desert wasteland instead of destroying it.
