coverage of Arctic sea ice ever recorded. Mount Everest In May 2010 Pugh swam across Lake Pumori, a glacial lake on Mount Everest, to highlight the melting of the glaciers in the Himalayas and the impact the reduced water supply will have on world peace. Millions of people from India, China, Pakistan, Bangladesh and Nepal rely on the water, which flows from the Himalayan glaciers. The swim, at an altitude of 5,300 metres, in 2 °C water (35 °F), took 22 minutes and 51 seconds to complete. The Seven Seas In August 2014 Pugh undertook the first long-distance swim in all the Seven Seas to campaign for more Marine Protected Areas in the region. The swims took place in the following locations: Mediterranean Sea – a 10 km swim off Monte Carlo in Monaco Adriatic Sea – a 10 km swim off Zadar in Croatia Aegean Sea – a 10 km swim off Athens in Greece Black Sea – a 10 km swim off Şile in Turkey Red Sea – a 10 km swim off Aqaba in Jordan Arabian Sea – a 10 km swim off Rass Al Hadd in Oman North Sea – a 60 km Thames swim from Southend-on-Sea to the Thames Barrier, east London. Afterwards Pugh wrote in an op-ed in The New York Times that he had "seriously underestimated the urgency" of the issue he undertook the swim for, noting that he saw "no sharks, no whales, no dolphins" and "no fish longer than 30 centimeters". English Channel In July and August 2018, Pugh swam the entire length of the English Channel – the second person ever to do so after Ross Edgley completed the feat a month before during his 1,780-mile circumnavigation swim around Great Britain. He left Land's End in Cornwall on 12 July and arrived in Dover on 29 August, after 49 days at sea. He swam between 10 and 20 kilometres each day in order to cover the distance. Pugh swam the 528 kilometres (328 miles) to call for 30% of oceans to be protected by 2030. He was greeted on landing at Shakespeare Beach by UK Environment Secretary Michael Gove, who described him as a "modern day hero" and a "brilliant champion for marine conservation zones.' Kayaking In September 2008, Pugh, accompanied by a team aboard a ship where he slept, attempted to kayak the 1,200 km from Svalbard, across the
