Of course, the people who are most directly affected by this are the Africans who are poor. Poverty affects them by reducing their life chances and even their life spans. They are typically unable to become educated, to get their children educated, or to have access to good health care. This makes it more likely that they will continue to be poor and may well have shorter lives than they should have given the state of medical technology in the world today.
While these is the most important effect of poverty in Africa, this poverty also affects other people. For example, poverty in Africa is a major cause of the conflicts that arise in that continent. These conflicts, along with famines and other things, have an impact on other people. They might, for example, cause the US and other nations to have to spend money on relief efforts or to spend money and even lives trying to prevent or end conflicts.
