Reuters photographer Clodagh Kilcoyne: The thing about an old rusty tractor, said cockle-picker Tony McClure, is that even in the sea air, it will start. His was parked out on the tidal flats of Flookburgh sands in Morecambe Bay in northwest England, braving the salty shallows of an unusually warm February dawn. He was comparing old mechanical tractors to the more modern electronic kind, and I was well aware of what he was talking about. The tide here comes in fast: If you're not careful, it can swamp a vehicle. So you want be certain to get off that seabed. McClure 39, was one of the first people I met on a February-March assignment around England's coastline, where I was photographing and talking to people who had voted to leave the European Union. Like most of the 50 or so people I met and spoke to while traveling from Morecambe to St. Agnes in Cornwall, McClure wants Britain to get out of the EU.

An aerial view shows the block of flats called "Le Signal", which was closed after heavy erosion caused by storms last winter on the Atlantic Ocean coast, in Soulac, southwestern France, June 18, 2015. France's Atlantic Ocean coastline, with its picturesque beaches, sandy between the Gironde estuary and the Adour River, and rocky in the Basque Country, diminishes several meters every year. Erosion from recent winter storms, with huge waves and unusual high tides, have threatened buildings and private homes on the coast, with a reduction of the beachfront by 10 meters in certain areas, the Aquitaine Coast Observatory said. Paris will host the World Climate Summit, called the COP21, from November 30 to December 11, 2015. Picture taken June 18, 2015 REUTERS/Regis Duvignau

A trader watches television as he sits in his shop in a television, satellite and computer shopping centre in Kabul March 3, 2014. Despite decades of conflict in Afghanistan, and several recent militant attacks, the country's capital Kabul is home to a vibrant youth scene of musicians, artists, athletes and activists. Shopping malls and cafes stand in the city, which is nonetheless beset by infrastructure problems and instability. Afghanistan is preparing for an election on April 5 that should mark the first democratic transfer of power in the country's history, but it has been hit by a tide of violence as the Islamist Taliban movement has ordered its fighters to disrupt the vote and threatened to kill anyone who participates.
