epa03220098 Three pizza delivery workers deliver hot pizza to members of the salvage crew and crew onboard the Japanese fishing trawler, Eihatsu Maru, after it ran aground off the exclusive Clifton beach in Cape Town, South Africa 15 May 2012. A second attempt to tow the vessel out to sea failed when the tow line snapped. The 50 meter (164 foot) Japanese fishing trawler ran aground close to the shore in the fog on 12 May 2012 with 28 Taiwanese crew and a dog on board. The vessel grounded  35 meters from the upmarket Clifton Beach with million dollar apartments overlooking the striken vessel at the foot of the iconic world heritage site, Table Mountain. Following the failed attempts to refloat the vessel 90 tons of oil will now be pumped off before a third attempt.  EPA/NIC BOTHMA

"On Tuesday, May 15, tens of thousands of people across the world pointed cameras - and cellphones - at everyday life, with all its joys and sorrows. Professional and amateur photographers got involved: students, doctors, cleaners, journalists, astronauts, politicians and truck drivers. Everybody committed to this simple idea - using a camera to send a message, to our own time and to the future."

This is the foreword, written by UN deputy secretary-general Jan Eliasson - to the book A Day in the World, which is a compilation of 1 000 photographs from 100 countries including South Africa.
