It's selfish humans playing God again.

Over here, the grey (Sciurus carolinensis) which is a native of the
eastern parts of the USA is vermin. it is an introduced pest species
which causes significant damage to forestry, and spreads disease which
is endangering the native red (sciurus vulgaris).

If humans hadn't played God and introduced the little blighters to this
country (and to Ireland and Italy, if Wikipedia is to be believed) we
wouldn't have this problem.
