I live in a country (not US) that has been isolated from many countries for millions of years and had many invasive species introduced by humans in the past few hundred.

These invasive species have devastated local/native wildlife and grown to ridiculous levels. If humans did nothing to stop them, including hunting them, they would completely take over and extinct many more species than they already have, reducing diversity.

Not stopping them, again which includes hunting and trapping, would be amoral and worse for the planet
