Using them maybe not, but producing them and then shipping them across the globe? Also, as with all things, its not like one iPhone in isolation is a problem, but millions, year after year, that does add up.

Maybe that's still not much compared to other industries, but in the context of the conversation here, its still something that an individual who might complain about climate change does have a little control over. I mean, if I complain, but then don't change MY behaviour, even if that change wouldn't by itself change anything, why should I expect companies to change theirs?
