People Fixing the World Folgen

Farming animals for meat has a massive environmental impact, both in terms of land use and carbon emissions. But in order for people to eat less meat, they need to be excited about the alternatives. Around the world, people are coming up with ingenious meat replacements that look, taste and smell more like the real thing than ever. In Switzerland, we visit the perfume company that’s now turned its hand to perfecting the flavour in veggie burgers. And in Nigeria we meet the entrepreneur who has devised an alternative to beef and chicken that he hopes will appeal to West African tastes. Plus, we speak to the start-up in Israel that’s making kosher veggie ‘meat’ using a 3D printer.

Police forces in the US are turning to futuristic technology to tackle a rise in violent crime and murder across the country. In one area of California, they are even using robots to patrol the streets. There, the police are claiming it's led to a reduction in crime and an increase in arrests. In New York they even experimented with a robot police dog, but with mixed results. This and other cutting-edge technologies are helping the police – and the public - stay one step ahead, but they are often controversial. In this programme we look at the some of the best ways that technology can make the streets safer. Presented and produced by Ben Wyatt Image: The Robocop K5Repeat - first published 5 October 2021

We look at two new pieces of health technology which allow medics to treat people without touching them. Breast cancer fatality rates in India are higher than in other countries because women are often reluctant to go for screening. A start up called Niramai wants to change this. They use thermal imaging and machine learning to screen for breast cancer without patients having to be seen or touched by a doctor. Plus, we hear about a new company using augmented reality to connect surgeons in operating theatres around the world. Proximie allows medical professionals to help or observe surgery in progress from anywhere on their computer or tablet. It’s already been deployed in 500 hospitals.Presenter: Jo Mathys Reporters: Chhavi Sachdev and Lucy Burns Produced by Lucy Burns for the BBC World Service. Picture: Remote operation (credit: Proximie)
