Just heard about Minga ..

Minga works to end the commercial sexual exploitation of children
through youth education and empowerment.

“Minga,” comes from the Quechua language of Ecuador and means “the
coming together of a community to work for the betterment of all.”
With your help, we can end this cycle of exploitation.

They've got chapters all over the place and are all about engaging
young people in taking action in some way. Additionally, they're
always seeking interns and are currently seeking staff. Translation:
get in touch with them @ mingagroup.org To bring them to your class
or campus, email speak@mingagroup.org
