People Fixing The World Folgen

More than a quarter of Japan’s population is over 65 and the country has the highest rate of centenarians in the world. It’s a ticking demographic time bomb as the cost of caring for the elderly rises. But can the solution to this growing problem be found in Kashiwa City near Tokyo? A project there has been looking at how to redesign towns and cities to adapt to their residents as they reach old age. World Hacks asks whether the answers they have found could help ageing populations across the world. Producer: Harriet Noble (for BBC World Service)

Just over a year ago, Kenya introduced the world’s most draconian rules on single-use plastic bags. People can be fined up to $40,000 or even thrown in jail for producing, selling or using them.World Hacks travels to Nairobi to find out what impact the ban has had, and asks why Kenya has taken such a seemingly progressive stance on plastic. We also speak to experts in the UK to find out why many governments prefer to ‘nudge’ their citizens into cutting back on plastic bags, instead of banning them.Presenter: Amelia Martyn-HemphillPhoto Credit: Getty Images

Child abduction by strangers is extremely rare, but the danger looms large in the minds of many parents. One reason is that for the past 50 years or so, governments have created public information campaigns around the message of “Stranger Danger”. In the UK, the US, Canada and many other countries too, these videos were played in the media and in schools. The videos portrayed in stark terms the risk of talking to adults you did not know who appeared to be friendly. But a new generation of childcare experts believe this is not the most effective message to protect children. Most abductions are by people children already know. And there is a worry that a general fear of strangers is not good for a child’s social development - or for society in general. World Hacks meets the charity Action Against Abduction as they teach a new message: Clever Never Goes.
