For some specialized nonprofit agencies, the mission is to reach a particular group of people in need. The organization Give Running serves one such goal by providing shoes to children around the world. By collecting, cleaning, and distributing thousands of pairs of gently used athletic shoes Give Running makes a difference for children in need, including some who have never owned athletic shoes of any kind. Originally the project of a college student in California, the nonprofit grows via more local chapters and shoe collection sites. Donations have gone to the kids of inner-city Los Angeles, to Haitians after the earthquake, and to African villages. The shoes represent opportunity for kids to run and grow. In some countries in the developing world, children are only allowed to attend schools if they have shoes to wear. Not only do shoes protect feet from injuries and allow children to walk safely to school, the donated shoes themselves help make schooling possible. An additional benefit of these donations is that most shoes are being recycled, keeping material out of landfills. Finally, this growing organization accepts and distributes all types of athletic shoes, and is eager to expand. Which of the following sentences from the paragraph is the topic sentence?
