People Fixing the World Folgen

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 and lithium – he has found that some of them demonstrate a remarkable improvement in mood, which can last indefinitely.The therapy has caught the attention of researchers across the world, and new trials are being carried out, but the idea is not without its critics.Sam Judah spends a week with a cohort of patients as they undergo sleep deprivation treatment at the San Raffaele hospital in Milan, and tries to find out if it is effective.Producer: Sam Judah(Photo caption: Francesco Benedetti / Photo credit: BBC)

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 shoppers cutting down on packaging by buying in bulk, people organising litter-picking trips to clean up plastic from the desert and an idea to create giant floating plastic pontoons as platforms for new housing. There are some surprising tips too, like from the woman who reuses empty pet food sachets to store her pre-cooked meals in the freezer and the man who melts down his own plastic waste and turns it into fence posts.Presenters Kat Hawkins / Nick Holland Producer Nick Holland (Photo credit: Getty Images)

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 of land there is devoted to cattle ranching. The land that’s been cleared to graze cattle is often left without trees, meaning the soil quickly becomes arid and useless. Now an ambitious project aims to demonstrate that cattle ranching can be ecologically sound. An expert team is helping more than 4,000 farmers dramatically remodel their land. Instead of open fields, they are planting trees and shrubs, and allowing small plants to grow among the grass.This more intensive planting helps to store carbon and provides a healthier diet for cows, meaning they produce less methane and more milk and meat. But are other cattle farmers likely to follow suit and adopt this “silvopastoral” approach?Presenter: Kat Hawkins Reporter: William Kremer(Photo credit: BBC)
