Keep in mind that this applies to... well, most famous people. Swift isn't the first to do it and she unfortunately won't be the last. (Al Gore, for example.)
Friendly reminder that a single trip some celeb or other rich asshole takes on a private jet releases more co2 than a single person like us could use in like a decade. But they'll shame us for using plastic straws or eating meat. Fuck em. Swift is already upset at the backlash, don't give her or any other celebrity a moments peace.
