If the IWW ran a strip mine it would still be destructive.  If the
Wobblies ran the world's largest lumber mill (Pacific Lumber's) they
would still need to clearcut to achieve full utilization of that mill.
If they did not continue exploiting natural resources in the most
expedient and efficient manner they would cease to be competitive with
their more capitalistic counterparts.
If the wobblies ran Monsanto the genetically engineered crops would
still pose unknown risks (and possibly known but not revealed risks as
is currently the case) and the pesticide and herbicide production and
use would still be toxic.  If the IWW ran Union Carbide the Bhopal
disaster still would have happened.
It could be that factories which put the workers and the environment
ahead of the market demand might find it harder to stay into business.
If a wobbly asks, "Would you like fries with that?" and doesn't wear a
smile, the meal just wouldn't taste as good.
