14 women using social media to change the world Sophie Sandberg @catcallsofnyc

Tired of being unable to walk down the street without being constantly catcalled by men, activist Sophie Sandberg took to Instagram to expose an epidemic rife in society. Armed with multi-coloured chalk, she began documenting the horrific words that had been said to her all over New York in late 2016. Talking to the BBC about the project she stated: 'By writing [catcalls] in the same place that it happened, I hope the words may remember and think "Oh those were my words".' Women around the globe have been inspired by Sandberg’s work and Instagram accounts of women chalking messages have since sprung up from Columbia to Bangladesh.
