It's really a great point, Apple's vision of a wireless world will have significant consequences on the environment regardless of recycling programs or education, it will be an extra burden for which there is no guarantee the public will follow advise, in fact statistically it's a norm that recycling is done by a minority of the public (only 12.5% of e-waste is recycled according to EPA) . You say you will recycle, but that's only you, 1 person, the rest of the public is likely not to, and there isn't any additional campaigns or initiatives from Apple to address the environmental impact.
So the price to pay for convenience is not insignificant, and in fact I think it's questionable whether it's really needed for the mainstream public, I think a lot of people really don't mind cables in headphones, yet Apple pushing for wireless is going to make people that didn't mind it before, go wireless and put extra burden on the environment. So it's a great point of consideration and one that shouldn't be dismissed so easily like you are doing.
