Theroux began presenting documentaries for
Channel 4's
Unreported World series in 2000. In 2004, he presented
The End of the World as We Know It, part of the
War on Terra series about
climate change. He was chosen as presenter because he originally knew nothing about the subject. He initially believed that all environmentalists were opposed to technological progress, but became convinced that the world faced a global problem on a scale so serious that an expansion of nuclear energy was probably the best solution. He interviewed
Shell chairman
Ron Oxburgh, but a PR assistant interrupted them; Oxburgh's negative views on the consequences of current oil consumption were likely considered detrimental to the corporation's image. In March 2006, Theroux presented
Death of a Nation on
More4 as part of the
State of Russia series. In the programme, he explored the country's
post-Soviet problems, including population decline, the growing AIDS epidemic, and the persecution of the
Meskhetian Turks. During interviews, he revealed that he is able to speak basic Russian. In September 2008, he presented
Oligart: The Great Russian Art Boom, exploring the role of
Russia's oligarchy in keeping the country's art history alive by buying and exhibiting domestic art. In March 2009,
Faber & Faber published Theroux's novel
Far North, a future epic set in the
Siberian taiga. That month, he presented
In Search of Wabi-sabi on
BBC Four, as part of the channel's
Hidden Japan season of programming. He reported from Japan to explore the aesthetic tastes of Japan and its people. In 2012, he presented a documentary for
Unreported World Series 23, on the subject of street children in
Ukraine. Theroux's novel
Strange Bodies won the 2014
John W. Campbell Memorial Award for Best Science Fiction Novel. In 2017, he presented a documentary for
Unreported World which explored the social and economic consequences of the recent rise in Orthodoxy and Russian nationalism under
Vladimir Putin. In 2020, he presented another documentary for
Unreported World, which explored middle-aged single Japanese men's obsession with
junior idols and whether this was a quirk of Japanese culture or something more sinister. ==Personal life==
