For Two 4 Change, one of its three main goals/activities will be healthcare. Two 4 Change will focus on delivering support for the Health Centers located around Tanzania. Much of that support will be delivered through the important volunteer work and donations of our support network overseas. Disease and poor sanitation threaten the health of Tanzanians. Only about half of the population has access to clean water. More than 1.4 million Tanzanians live with HIV and AIDS, and almost 1 million children have lost one or both parents to the disease.
