Labels:text | font | screenshot | white OCR: Sao Tome has no mineral resources, although oil prospecting began in 1990. Almost all energy needs, apart from firewood, are met by oil imported from Angola. Sao Tome is very fertile; cocoa estates are finally back to pre-1975 productivity and crop diversification is now a priority. Principe has better ports, but its wild scenery makes it more suitable for tourism than farming.
