Author Henry Hitchings explores the lives and works of Britain's radical and pioneering 18th-century novelists who, in just 80 years, established all the literary genres we recognise today. It was a golden age of creativity led by Daniel Defoe, Jonathan Swift, Henry Fielding, Laurence Sterne, Fanny Burney and William Godwin, amongst others. Robinson Crusoe, Gulliver's Travels, Tom Jones and Tristram Shandy are novels that still sparkle with audacity and innovation. On his journey through 18th-century fiction, Hitchings reveals how the novel was more than mere entertainment, it was also a subversive hand-grenade that would change British society for the better. He travels from the homes of Britain's great and good to its lowliest prisons, meeting contemporary writers like Martin Amis, Will Self, Tom McCarthy and Jenny Uglow on the way.

Cannabis is the world's favourite drug, but also one of the least understood. Can cannabis cause schizophrenia? Is it addictive? Can it lead you on to harder drugs? Or is it simply a herb, an undervalued medicine? Addiction specialist Dr John Marsden discovers that modern science is finally beginning to find answers to these questions. John traces the cannabis plants' birthplace in Kazakhstan; finds the origins of our sensitivity to cannabis in the simple sea squirt; and finds out just what it does to our brains. He meets people who have been changed by this drug in drastically different ways - from those whose lives have been shattered to those who lives have been revived.

What's your idea of the perfect birth? Do you want every medical intervention known to science or do you want to go it alone, without the help of a doctor or midwife? And what about after birth? Perhaps you'll hang on to your baby's placenta and carry it around with your newborn until it dries and drops off naturally? Or maybe you'll decide to eat it by whizzing it up into a smoothie? This film follows four pregnant women all making very different choices around their births, all determined to do it their way." 37-year-old Jo plans to deliver her baby completely alone on board her barge, without the assistance of any medical professional. By contrast, 34-year-old Anna is opting to sidestep the pains of labour and book in for a c-section at the Portland Hospital in London. Anna wants all the medication available and she doesn't want to feel a thing. There are plenty of unusual plans for after the birth too. In Devon, 33-year-old Lisa plans to lotus birth - she'll leave her baby's umbilical cord attached to its placenta and she'll keep it fresh by dusting it with salt, rose petals and lavender oil. 35-year-old Kati from Manchester is going to whizz her afterbirth into a smoothie and consume it over a number of days. She hopes it will help her stave off post-natal baby blues and bounce back as quickly as possible. Fending off bewildered looks and concerns from friends, family and medical professionals, each woman is going against convention to have the birth she wants. There are free and frank discussions between mums and daughters and decisions to go against medical advice. So does breaking with the norm and sticking to your guns pay off? And what really is the perfect birth?

In a far cry from the steamy jungles of Rwanda or the icy waters of the Arctic, British naturalist Sir David Attenborough has donned a necktie and met with US president Barack Obama to discuss climate change and the future of the planet. The two met at the White House — a place the naturalist had never yet explored — on Sir David's 89th birthday in May to film the interview". It was the first time the respected wildlife filmmaker had met an American president and he seemed a little awed by the experience. Mr Obama, who grew up watching Sir David's programs, seemed equally thrilled. The president has the environment and climate change on his radar and is anxious to see progress made as his presidency comes to a close. He faces stiff opposition from Republicans in Congress on his plans to tackle climate change, but remains determined to make changes before leaving office. "I don't have much patience for anyone who denies that this challenge is real," he said. "We don't have time for a meeting of the Flat Earth Society." Sir David, who has been called "the godfather of natural history TV" by the BBC, brought to the meeting six decades dedicated to sharing the wonders of the natural world with television audiences. After initially being rejected for television because his teeth were deemed "too big", Sir David went on to make his Life on Earth television series, which has been watched by more than 500 million people worldwide. His name is now synonymous with nature, conservation and wildlife. During the television interview, the men discussed global warming, renewable energy and how children and young people hold the key to reversing the damage.
