International Women's Day is always such a bittersweet occasion—an opportunity to draw attention to the challenges facing women worldwide, but also an opportunity to celebrate women—all that we are, all that we do, and all that we have achieved. The Irish charity and development agency Trócaire has recently launched a gender equality campaign to raise awareness of the inequalities that come simply with being born female: you can watch the campaign's powerful TV ad below.

Campaigns like Trócaire's are essential in a world where women face daily threats to their health and well-being, but the good news is that today, and every day, all over the world, women are standing up to demand change. Earlier this week, 30 women in Iran were arrested for doing just that—in a clear demonstration of just how threatening a powerful group of women can be. Today in Nicaragua, women will march once again for their own right to life, and they'll keep marching until the government guarantees it. International Women's Day doesn't get a lot of attention in the States, but for women all over the developing world, it's a major occasion. Stand with them in solidarity today!
