Marley Dias loves nothing more than getting lost in a book. But the books she was starting atschool were starting to get on her nerves. She enjoyed Where the Red Fem Grows and The Shilohseries, found in so many primary school classrooms, were all about white buys or dogs-or whiteboys and their dogs. Black girls, like Marley, were almost never the main character.

What she was noticing is actually a much bigger issue: fewer than 10 percent of children ’sbooks released in 2015 had a black person as the main character, according to a yearly analysis bythe Cooperative Children’s Book Center. In November 2015, Marley set out to gather 1,000 bookswith black girls as protagonists(主角). Her campaign called”1000BlackGirlBooks”was a bigsuccess. (79) She far exceeded her goal and collected more than 10,000 books!”Through mycampaign, I want to give kids a stronger sense of identity. ” Marley says. (80) ”

The biggest thingI’ve learned is that kid’s voices need to be heard.” In the future, Dias wants to be the editor(编辑) of her own magazine. She is already makingthe steps toward having a successful and meaningful career At 11, she ’s aware of the racism inthe publishing industry. Like the television and movies, the publishing industry does not represent black girls orother people of color in positive ways. The white washing(漂白) in this industry extend beyondnot having people of color as characters. In 2012, white men wrote 88% of the book reviews. In 2013, only about 2% of the books were about black characters.

Then if there are people of colorin the books, the publishers attempt to whitewash people of color on the covers. However, Dias is making it a little easier for other black girls searching for a character that isjust like them. Her project is a positive step toward young black girls seeing and experiencingtheir lives in books.

Which of the following is the best title for the passage?
