Habitat for Humanity International ― or Habitat ― is a nonprofit organization that helps people in need build houses. Since 1976, volunteers for Habitat have built more than 350,000 houses worldwide. According to Habitat, however, there are still more than 1.6 billion people in the world without decent housing. In the article below, Mariko Asano talks about her experience as a Habitat volunteer. She has traveled to the Philippines three times to help build houses for people who need them.
