I think it’s time, now that yet another carbon spewing species has been added to Azeroth’s denziens (aka mechagnomes), to consider the impact this will have on the environment.
Orgrimmar and surrounds is already vastly deforested and Ashenvale is on it’s way there. Lets also not forget that a world tree was burnt to a crisp and who knows how many tons of carbon emissions that offset in the past and is now gone.
We should definitely insist on carbon scrubbing technologies with these races, especially goblins as they are most polluting.
Else punt them off the tops of the cliffs to discourage them from their current behaviour, since all the tinkering classes are conveniently puny.
