At a vast dumpsite in the west of Ghana’s capital Accra, small fires burn among piles of old computers, television screens and laptops, throwing clouds of thick black smoke into the air. Around them workers pick out motherboards, valuable metals and copper wires, burning away the plastic coverings as they go—[3]filling the air with poisonous fumes.
