Martin is a writer, surfer and beach lover. He founded the Beach Clean Network with Tab Parry in 2009 and started the #2minutebeachclean in 2013 after North Atlantic storms left UK beaches littered with plastic rubbish. It's a simple, effective idea - pick up beach litter for 2 minutes, bag it, tag it, bin it - and the mission has been taken up by thousands of people around the world.
Martin is also the author of the bestselling series The Camper Van Cookbook, The Camper Van Bible and The Camper Van Coast and presented the BBC2 show called One Man and his Campervan.
He lives in Bude, Cornwall.
