Harper’s BAZAAR’s interview and photo shoot with singer and activist Annie Lennox from the March issue (currently on newsstands) discusses her hashtag campaign #OneReasonWhyImAGlobalFeminist.

The iconic singer, songwriter, and activist is using social media to spread awareness of the extreme injustices faced by women and girls worldwide. In honor of International Women’s Day today, she wants you to join her.

Here aree some Annie Lennox Quotes:

On how #OneReasonWhyImAGlobalFeminist came to be: “I looked at the T-shirts and I was like, ‘Oh, my goodness, what if Wonder Woman could connect everyday women and men to the facts about the gender inequality experienced by millions of girls and women every day around the globe?’ So I bought the T-shirt, took it home, and put it on. Then I wrote a list of facts and statistics on sheets of drawing paper and had a series of pictures taken for Instagram of myself holding up the messaging.”

On popularizing global feminism: “Feminism is a broad church containing varying beliefs and interpretations, but schisms exist that can prevent us from reaching our full potential. I’ve witnessed for myself how girls and women are extremely disempowered throughout the world. Gender-based violence is played out everywhere—in New York, in Nairobi. It is endemic at a global level.”

On including men and boys in the movement: “I think men sometimes feel uncomfortable saying ‘I’m a feminist.’ But when we say we’re global feminists, we’re giving them the key to be a part of the movement. So much of it goes back to teaching men how to treat women as people just like them, as opposed to seeing them as the property of men in their lives.”
