In the UK there's many invasive non-native species, such as grey squirrels: they come from another continent, they are replacing the beautiful native red squirrels, they are damaging property, and are considered a pest.
To counteract this, the UK has many programs hunting and killing the grey squirrels, in fact it's even been made illegal to not kill them if you catch one
