Help on global issues essay for college application?

I’m applying to Georgetown with an intended major of Culture Politics and I’m having trouble with my last essay. Here’s the prompt:
Briefly discuss a current global issue, indicating why you consider it important and what you suggest should be done to deal with it.

I’ve chosen to write about women’s oppression globally then boil it down to how it exists in the US. My problem is in what specifically to write about. Women’s oppression comes in various forms such but I can’t seem to pick one general area to focus on. Any ideas?
