Abbreviated books, short-form TV, time-management gurus - has the cult of speed gone too far and is it time to slow everything down?

Ed Butler speaks to two business people hoping to cash in on our ever more hectic lives: Holger Seim co-founded Blinkist, which offers boiled down versions of long-form non-fiction books, while Perrin Chiles runs Adaptive Studios, which produces TV mini-dramas squeezed into slots that can be as short as 10 minutes.

But rebellion is afoot in the form of Carl Honore, whose unabbreviated book, In Praise of Slowness, pushes back against our culture's supposed need for speed.

Coal fires used to beat the bitter cold of Mongolian winters blanket capital city Ulaanbaatar with smog in the winter, the BBC's Roger Hearing finds, when he meets residents from the Ger District.

Typical sanitation is makeshift and in the form of latrines, says Choikhand Janchivlamdan, a sanitation expert at the Green Initiative. This can lead to the spread of disease. Lost livestock due to harsh winters and a desire for better education is leading people to the city, she says. As people move to the city from the countryside, the problem gets worse as no new sewage systems are built.

Tserenbat Namsrai, Mongolia's environment minister, plans to introduce smokeless fuel in a bid to combat pollution and introducing more electric heating.

Robert Ritz, a US professor who lives in the city, says PM2.5 particulates - that's atmospheric particulate matter that have a diameter of less than 2.5 micrometres - kill thousands of people per year.

Ed Butler and BBC politics correspondent Rob Watson explore the difficult choices that London politicians still refuse to face up to.

Germany is booming, yet some commentators suggest the nation's loss of confidence on the football pitch may mirror economic angst back home.

A shortage of skilled workers, inadequate public investment, a failure to grasp new technologies - these are just some of the criticisms that Germans level at their own economic performance. And at the heart of it is a political crisis over the influx of migrants - something many economists say is sorely needed in this ageing nation.

Anna-Katarina Noryskiewicz reports from Berlin, plus presenter Rob Young speaks to Gabriel Felbermayr, director of the Ifo Centre for International Economics in Germany.

Harley Davidson and Mid Continent Nail Corp are some of the US employers being hammered by America's escalating tariffs spat with its biggest trade partners.

Manuela Saragosa asks Vanessa, the author of The Girl On A Bike blog, what Harley fans like her make of the company's decision to move some motorcycle manufacturing from the US to Thailand in order to dodge new EU retaliatory tariffs. James Glassman of Mid Continent explains how the blow from the US President's steel import tariffs may flatten his company altogether in a county that voted 79% for Mr Trump. Plus former US trade advisor Pippa Malmgren explains why it may be wrong-headed for her government to try to address the country's perennial trade deficit in the first place.
