One of the most captivating exhibits in the Newseum is its collection of Pulitzer Prize–winning photographs. The images curve along the gallery’s wall and are paired with videos of the photographers discussing their experiences trying to capture the right shots. The Newseum’s latest exhibition, “40 Chances: Finding Hope in a Hungry World—The Photography of Howard G. Buffett,” also draws visitors’ attention to lesser-known spots in the world through powerful photographs. But this isn’t the artistic vanity project of a wealthy man—it’s the philanthropist’s way of combining his passion for photography with his work promoting sustainable farming practices and combating the global hunger crisis. Buffett traveled to more than 135 countries, documenting different communities’ experiences with hunger and poverty. The title of the exhibit comes from Buffett’s belief that people have 40 chances to achieve their goals in life (just like farmers have 40 growing seasons to establish a healthy harvest). Buffett wants to raise awareness about, and educate and empower people to find ways to end, hunger. Also on display is an interactive kiosk where viewers can learn more about global food security programs and ways to get involved. The exhibition is on view daily 9 a.m. to 5 p.m. at the Newseum, 555 Pennsylvania Ave. NW. $13.95–$22.95. (202) 292-6100. newseum.org.
