Costa Rica has just made street harassment illegal!
The other countries who have legislation place are Argentina, Belgium, Chile, France, New Zealand, Portugal. As you can see...the UK is not on the list
Yet almost 70% of women have experienced sexual harassment in a public place, and 38% of girls experience verbal harassment at least once a month. See - https://plan-uk.org/file/plan-uk-street-harassment-reportpdf/download?token=CyKwYGSJ
There are some incredible campaigners out there including Our Streets Now who have a wealth of information on their website where you can also sign their petition - http://ourstreetsnow.org and https://www.change.org/p/make-street-harassment-a-criminal-offence-in-the-uk
We also really love the work by Hollaback London. You can find resources on how to combat street harassment and be an active bystander here - https://www.ihollaback.org/bystander-resources/
