How to move the Earth
People Fixing the World
Dec 31, 2019

Using lasers or asteroids to move our planet away from the sun may sound extreme, but a few scientists have come up with plans to do just that.

The sun’s power is slowly increasing. Over the next billion years or so, the extra energy is going to boil off the oceans and make the earth inhospitable.

Given the timescales involved, you might think this is someone else’s problem. But such is the human enthusiasm for problem-solving, potential solutions have been found - from shooting asteroids past the Earth to creating a gigantic solar sail.

We meet the scientists who are trying to figure out how to save the planet from the sun.

Tackling bias in health

Bias in the way medical research is carried out means that new medicines for diseases such as cancer – as well as the tools used to diagnose patients with some conditions – are disproportionally tested on people of European heritage. This can lead to those not represented in the data being misdiagnosed as well as some treatments not working as well as they should.

From the Ghanaian scientist helping to develop cancer treatments which work better for African people, to the team in England using AI to diagnose dementia in communities where English isn’t widely spoken, in this programme we will meet the solution-seekers trying to make healthcare more equal.

People Fixing The World from the BBC is about brilliant solutions to the world's problems. We'd love you to let us know what you think and to hear about your own solutions.

Gadgets for blind people

Myra Anubi is joined by BBC Access All presenter Emma Tracey to look at new technology that could help blind people in their everyday lives. Glide is a new mobility aid – it’s a device with wheels and cameras that aims to provide blind people with an alternative to white canes and guide dogs, while using AI to give them more information about their surroundings. Emma tries the gadget out in Los Angeles. She also looks at a device that is much simpler but in its own way revolutionary – the BrailleDoodle is a tactile tablet that makes it easy for blind children to learn braille, create art and understand graphs and diagrams.

How sport can bring outsiders in

This week we look at two projects that show how sport can be a powerful tool for social inclusion.

We go rowing with some refugees in Seville, Spain, and discover how being part of a crew has helped both adults and kids feel part of their new community.

And we join a special scheme in southern England that uses football coaching to break down barriers between police officers and local young people. The project is run by Brighton and Hove Albion Foundation in partnership with Sussex Police.

Recovery for all

There are more people alive and living for longer - but with that comes more people experiencing failing health. While some of this is inevitable, some can be reversible through rehabilitation.

The WHO says 2.6 billion people could benefit from rehabilitation services but in low and middle income countries fewer than half receive these services. We’ve found three projects which help promote independence and a better quality of life.

We hear how training doctors and nurses in basic rehabilitation skills is changing lives and communities in rural areas in countries as diverse as Uganda, China and Fiji.

We find out about the bracelets which look set to reverse some effects of Stroke and open the door to recovery. And we meet the online community of physiotherapists who are helping mentor new physios around the world.
