A Google Doodle has just been posted celebrating the 100th anniversary of International Women's Day.

Clicking on the doodle will takes you through to the website, which gives information on how you can get involved by joining, "tens of thousands of people coming together on bridges all over the world - from the Millennium Bridge in London, the Brooklyn Bridge in New York City, the Golden Gate Bridge in San Francisco, to the Grand Barriere Bridge joining Rwanda and Congo - to show your support for women's causes and celebrate women's achievements."

What's interesting to note, when looking at the map of the different bridge events, is where activity is not taking place; conspicuous by its absence, it's invariably in places where women don't have the time, or are oppressed and not allowed to congregate to celebrate women's achievements, that bridge events are absent.

Despite doing more of the work in the world, women get paid less, own less land, and have less time and freedom than men - and although we talk about a post-feminist era it highlights that feminism is needed now as much as it ever was in the past.

Long associated with man-hating, feminism has steadily become increasingly unfashionable as it tries to shrug off the label - but its core idea, of quality of opportunity, should not be forgotten and hopefully International Women's Day will do something to highlight that equality of opportunity is needed for women everywhere.
