Wanda Butts dropped the phone and screamed when she heard the news that her son was dead. Josh had drowned(溺亡) while sailing on a lake with friends. The 16-year-old didn’t know how to swim, and he wasn’t wearing a life jacket.

Josh was not alone in the black community. USA Swimming points that 70% of African-American children cannot swim. According to an official survey, African-American children between the ages of 5 and 14 are three times more likely to drown than white children in the same age range.

In 2007, Butts started the Josh Project, a non-profit(非营利组织) that provides low-cost swimming lessons for children in Toledo, Ohio. The swimming lessons take place at a local high school over four Saturdays for a total of 10$. Up to now, the Josh Project has helped more than 1,000 children learn how to swim.

“The public pools near our home are closed, and other places are not affordable,” said Lisa Haynes, whose 14-year-old son, Joshua, is one of 60-plus students in the Josh Project this summer. “I am less worried if Joshua is near water because he has the basics of how to swim,” Haynes said. “And we’re thankful for that.”

Butts is doing much more, however, than just providing swimming lessons.

“She ups the awareness(意识),” said Shaun Anderson, a swimming coach who was so inspired by her story that he created a Josh Project swimming program at Norfolk State University. “Once these communities(群体) learn how to swim, they will pass it down, which results in future generations that know how to swim.

Butts said she has two wishes for the future: One is to change the drowning numbers of African-American children, and the other is to have a swimming center where the children can swim every day instead of just once a week.
