"When Canadian Mennonite University (CMU) professor [Ray Vander Zaag] returned to Haiti earlier this year after an 11-year absence, he says, "It broke my heart to see how conditions have deteriorated for so many. Life is certainly getting more difficult for people there."One theory holds that the crisis is the result of how foreign governments have encouraged Haiti to open its markets to cheaper imported food. But as prices on imported food have risen, in part because of rising fuel costs, Vander Zaag notes that "it is harder for poor people to buy staple goods."Vander Zaag doesn't want to discourage North Americans from wanting to help people in Haiti. "But we need to do it in a way that doesn't cause more problems for them in the long-term," he says. Otherwise, we run the risk of just making things worse, instead of better."
