This Monday, Oct. 4, Habitat for Humanity will join efforts around the world to mark World Habitat Day, a day the United Nations has set aside to call attention to the dire need for affordable, adequate housing in all parts of the world. If you’re interested in helping out or checking out facts, videos, photos, banners or even submitting your own photo depicting what access to housing for everyone around the world means to you, visit the World Habitat Day site!
