People Fixing the World

Video games are often blamed for time-wasting and violence, but there’s a group of people proving this stereotype wrong. We meet the scientists behind a game designed to speed up finding a treatment for Alzheimer’s disease, and we speak to a teenager who plays it because “it’s something I can do to help people in my spare time”. Citizen science projects like this have had some remarkable successes...

The city of Vaasa in western Finland has built a reputation as a centre of innovation, where energy companies are working together to try to find solutions to some of the world’s biggest problems. Here, there’s a quiet conviction that climate change can be stopped and a belief that technology emerging from this area will help us make the shift to renewable forms of energy. We meet the people behin...

Imagine a grocery shop selling all your basic goods at a discounted price… and if you buy enough you also get free health insurance. It might seem too good to be true, but stores like this have been introduced at some factories in Dhaka, Bangladesh. Social entrepreneur Saif Rashid is trying to get better health care to some of the millions of garment factory workers who are on low wages. For them,...

Where there are humans, there’s waste. About two billion tonnes of garbage was produced in 2016, and the amount we generate is increasing. A lot of it ends up in unmanaged dumps or landfill sites. Much of it can’t be reused or recycled, but instead of seeing it go to “waste” some cement factories are using it to create energy. In this episode, People Fixing the World also looks at how tourists can...

If you have a cardiac arrest you need help immediately to have any chance of surviving. That’s why emergency call operators ask questions specifically designed to identify the condition, ideally within 90 seconds. Panicked and emotional callers don't always give simple answers, though, and evidence suggests cardiac arrests go unidentified in at least a quarter of emergency calls. In Denmark, a tea...

It's estimated that a person dies from a snakebite every five minutes. Many more people face life-changing injuries, losing limbs and consequently their livelihoods. Antivenoms are expensive to make and are in short supply, particularly in remote communities where they are needed the most. And what’s more, snakebites in different parts of the world need different types of antivenoms. Many of the c...

For the past 20 years, police chiefs and policy makers around the world have been fascinated by an idea: that violence spreads through cities like a disease, with patterns of clustering and transmission, and opportunities to inoculate communities against it. Violence-reduction programmes, influenced by epidemiology, have been implemented in Chicago, Glasgow and - most recently - London. But before...

In the 1970s hundreds of thousands of wells were dug across Bangladesh to give people access to cholera-free water. But this led to what the World Health Organization has called the largest mass poisoning of a population in history, worse than Chernobyl. That’s because the water in the wells wasn’t tested for arsenic. Decades on, it’s a major problem. The WHO says more than 35 million Bangladeshis...

Pollution, overfishing and oxygen depletion are damaging coastal waters across the world. Often fish and other marine life are the victims, but scientists are using one surprising creature to help solve the problem – the oyster. Oysters eat some chemical pollutants and fight algae blooms, which can have a damaging effect on biodiversity. A group of teachers and scientists in New York is trying to...

Concrete is the most used man-made product in the world but it comes with a heavy environmental price. Between 5% and 7% of the world's annual carbon emissions come from producing the cement that glues concrete together. Most of these climate-changing gases are released when a vital ingredient, limestone, is melted down in the manufacturing process. But one company has devised a new type of cement...

For the growing number of working women in Dhaka, commuting to work can be a challenge. The traffic is terrible and cars and taxis are expensive. Public transport is not only inconvenient, it is sometimes unsafe - many women face unwanted sexual attention on buses. So after his wife was harassed by a taxi driver, one young entrepreneur set up a motorbike ride-share service with a difference. Not o...

For most of human history, pumping carbon dioxide into the air has come free of charge. Burning fossil fuels powered the industrial revolution and powers most industries to this day. But all that carbon stays up in the atmosphere and dealing with the consequences won’t be free. The cost of climate change stretches beyond the lives lost in natural disasters. There will be a huge economic cost - to...

In the US most people who are charged with a crime can’t afford expensive lawyers and investigators to prepare their case. The public defenders who represent them usually have heavy workloads and limited resources. Family and friends would often like to help but don’t know how. So a group in California is trying to make things fairer by teaching them how the legal system works and explaining what...

It’s estimated that more than 100 million girls under the age of 18 will be married in the next decade. One country that’s trying to end the practice of child marriage is Ethiopia. There, the Berhane Hewan programme, meaning ‘Light for Eve’ in Amharic, promises families a solar-powered light if their daughter remains unmarried and in school until she’s at least 18. This approach is known as a cond...

Each year, mental health practitioners from around the world visit Trieste in Italy to see what they can learn from the city’s approach to mental illness. In 1978, Trieste led a ‘revolution’ in Italian mental health care by closing its asylums and ending the restraint of patients. Today the city is designated as a ‘collaboration centre’ by the World Health Organization in recognition of its pionee...

On average, one in eight children in the UK has a mental health disorder – that’s about three children in every classroom. Yet there are just 4.5 psychiatrists for every 100,000 young people - that’s fewer than most other European countries. With the UK’s mental health provision for children so stretched, help often ends up coming from families and schools. One school in London has actively taken...

Neighbours in the US are using cameras that read car number plates to record vehicles driving down their streets. When there’s a crime they check through the footage and pass any leads on to the police. But critics say the Flock Safety system, run by a private company, is open to abuse and warn of privacy concerns. Is it too risky to encourage residents to do police work, or a realistic response t...

More than five billion people around the world don’t have access to safe, affordable surgical care. It has been a big problem in Ethiopia where most specialist doctors are concentrated in the cities, contributing to high rates of maternal mortality. In 2009 the Ethiopian government began training Integrated Emergency Surgical Officers. Health workers, such as nurses and midwives, are taught to per...

In the 1990s Portugal had a major heroin problem, and when it came to people injecting drugs it had one of the highest rates of HIV infection in the EU. It took a radical approach and decriminalised all personal drug use. The law introduced in 2001 means people carrying drugs for personal consumption aren’t prosecuted - instead they are referred to health and social services to receive treatment,...

To prevent the worst effects of climate change, we need to massively cut how much carbon we pump into the atmosphere. But those carbon cuts might not happen in time, so another approach may be needed. Around the world, scientists, engineers and entrepreneurs are working on ways to give us more time to change our way of life. They’re developing technologies and techniques that effectively do climat...

People diagnosed with bipolar disorder are commonly treated with a variety of drugs. They aren’t always effective and can come with a range of side effects. For several decades, an Italian psychiatrist has been pioneering a different approach. By asking his patients to stay awake for 36 hours three times over the course of a week – and combining the counterintuitive idea with bright light therapy...

We hear what you, our listeners, are doing to tackle the problem of plastic waste. The idea came about when you started getting in touch after a previous episode asking why we don’t reuse and refill the plastic containers we’ve already got. (The Reuse and Refill Revolution: Tuesday 23 April.) Since then you’ve sent lots of alternative ideas and suggestions. Nick Holland and Kat Hawkins hear from s...

It’s not a good time to be a meat eater. Pressure is growing to tackle climate change – and the livestock sector produces 15% of global greenhouse emissions, with cattle farming accounting for two thirds of that. Not only do cows produce damaging methane gas, but creating pasture for the animals has led to widespread deforestation. Nowhere is this more evident than in Colombia: 34 million hectares...

Matsuri Takahashi was 24 when she died. She took her own life after doing more than 100 hours overtime a month at a large advertising company in Japan. She was a victim of karoshi - dying as a result of overwork. It’s a phenomenon that’s well known in Japan where stories of employees working ridiculously long hours – sometimes until four or five in the morning - are common. The government has intr...

Period poverty affects girls and women across the world who can’t afford to buy sanitary pads or tampons each month. So what are the alternatives? We look at two very different solutions. In a refugee camp in Jordan, we follow one woman as she tries to get a sanitary pad micro-factory off the ground. While in Malawi, they’re handing out menstrual cups to teenagers - which last for 10 years and don...
