The Americas With Simon Reeve
9pm, BBC Two
The outlook is a majestic yet bleak one for the opening to Reeve’s new series on the American continents. Landing among the soaring melting glaciers of Alaska before witnessing the gargantuan oil pipeline which cuts across the once-pristine wilderness of the state, Reeve presents a compelling indictment of the damage we are doing to our vital natural landscapes and resources. Travelling to Canada, he also sees the spread of drug addiction. A necessary watch. Ammar Kalia
Thomas Cook: The Rise & Fall Of Britain’s Oldest Travel Agent
8pm, Channel 4
It was the UK’s best-known travel agent, transporting holidaymakers in their millions until it left 150,000 of them stranded when it suddenly collapsed last month, requiring Britain’s largest-ever peacetime repatriation. So what went wrong? Ali Catterall
World on Fire
9pm, BBC One
Peter Bowker’s ambitious, sturdily constructed drama continues, its second episode concerned with characters taking decisions that will define their experience of the war. It’s less impactful than its opener but the scenes where ordinary Warsawians first meet the Nazis still have blunt shocks in store. Jack Seale
Sanditon
9pm, ITV
The enjoyable if freestyle adaptation of Jane Austen’s unfinished novel reaches its penultimate episode. Sanditon’s first ever summer regatta seeks to attract more visitors to the fledgling resort, with the men’s rowing race doubling as a clash for the heart of plucky heroine Charlotte (Rose Williams).

State of the Union
10pm, BBC Two
It has been eight weeks of nervy drinks and relationship therapy for our couple in crisis and now it’s time to look to the future as Nick Hornby’s endlessly entertaining series concludes. The typically dry dialogue continues, considering the prospect of yet more counselling. If that means another season, count us in. AK

The Loneliness of the Long Distance Runner 12.50pm, 5 Select
Expertly adapting his own novel, Alan Sillitoe and director Tony Richardson created the model of British 60s kitchen-sink drama. A waif-like Tom Courtenay is just right as the rebellious borstal boy persuaded by snooty governor Michael Redgrave to run in a cross-country race against the local public school. Paul Howlett
