What can Hollywood and other animation markets do to encourage and support women to work in the area?

Mentorship. I agree with Geena Davis—if young girls and women see other women working successfully in the industry, it will encourage them to follow and work for their own dream job in film and entertainment. If they see it, they can do it, too. This is also where I put in a plug for Camp Reel Stories, founded by the amazing Esther Pearl, which is a great non-profit summer camp where high school-aged girls can work together and make films.
