The difference, of course, is that musk's rockets don't claim to be environmentally friendly.
Complaining that windmills kill birds is rather more relevant, as it compounds with the unreliability and low productivity of wind turbines, as well as with other issues (chief being the enormous amounts of land that has to be cleared for them and the fact that wind requires dispatchable, conventionally fuelled backups for when it isn't blowing).
They are an inefficient, ineffectual waste of funds that should have been put into building out nuclear AND they kill birds.
