The world isn’t going to make itself equal. It’s going to take quite a bit of thinking, debating and doing to get women and men on a truly equal footing.

You can support the cause by pledging to take one of the actions below. You can invest in an African girl’s future, pester your MP in support of working women, or just pay a girl a compliment about her brain and not her body.

There are so many ways to show your support for gender equality, whether you have a minute, an hour or a day to spare. Every retweet or placard-wave matters.
