The #10YearChallenge — posting a new photo of yourself next to an old one — is being repurposed by social media users to highlight more serious issues than aging faces, from climate change to the devastation of war.
The trend started on Facebook, Instagram and Twitter with users including celebrities Jennifer Lopez and Ellen DeGeneres posting their current profile pictures next to one from 10 years ago.
But users quickly flipped the theme to photos spotlighting global concerns including climate change and the destruction wreaked by war in countries including Syria, Yemen and Iraq.
