Save The Planet and Take Me Home.... ?

Hainan Airlines has earbuds! The thing is, it says Save The Planet And Take Me Home.

But the thing is, if you take the earbuds home, plastic gets used and other materials are wasted because chances are, you already have earbuds. So, how do you waste plastic and save the planet from being over polluted? Some airlines like to REPACKAGE things like blankets, pillows, etc. and that​ can save the planet.
