It shocks, disappoints and angers me that in a world where man has travelled to the moon and where we can connect to people anywhere on earth instantly online, men and women are still not equal.

The statistics are sobering. Across the globe, gender-based violence causes more deaths and disabilities among women of child-bearing age than cancer, malaria, traffic accidents and war combined. Even in the war-ravaged Democratic Republic of Congo, it’s safer to be a soldier than a woman. Women do two-thirds of the world’s work for a paltry 10 percent of the world’s income and own just 1 percent of the means of production.

As the centenary of International Women’s Day approaches, I urge you to stop and think.

Last year, I did just that. I participated in one of 119 bridge events for International Women’s Day involving 20,000 women across four continents. It was a moving and powerful show of strength. I saw many wonderful women there, standing up for equality, justice and peace. But I was struck by how many other amazing women weren’t there.

It seemed to me that some people must think we already have equality. Nothing could be further from the truth. Yes, huge gains have been made since 1911, but we still have a mountain to climb. We need to persevere with this for the sake of our daughters, our granddaughters, and the generations to come.
