Hey
Taurens are known to take care of the environment, as much as the Night Elves, and they are also known for worshipping it.
The goblins entered in the Horde on Cataclysm : they don't care about the environment, it results in mass pollution, they drill several dirty & leaking petrol wells which destroy the environment and especially the surface earth which become impregnated and soiled by the petrol.
Why didn't they say anything about that ?
Also, taurens seems to be passive in the hord, they have absolutely no influence on the rest of the hord, despite being one of the first race to join it ...
