In Agbogbloshie, a slum in Accra, the capital of Ghana, adults and children tear away at computers from abroad to get at the precious metals inside. Left, David Akore, 18, and other foragers.

The equipment in this digital cemetery come mainly from Europe and the United States, sometimes as secondhand donations meant to reduce the “digital divide” — the disparity in computer access between poor nations and rich.
