We eat millions of tonnes of coconuts every year - with the dense white flesh of the fruit making a tasty snack and the juice a refreshing drink.But the inedible husk and shell go to waste – and it’s this part that innovators and entrepreneurs around the world are now putting to work to solve a whole host of problems.In Sierra Leone, a personal tragedy was the catalyst for young entrepreneur Alhaji Siraj Bah to start a business which takes the coconut husk and turns it into an alternative to charcoal - which is good for the forests and could potentially save lives too.And we’ll hear about the start-up using coconut to keep fish, fruit and vegetables cool for longer, without using any plastic.Presenter: Myra Anubi Reporter: Eric Mugaju Producer: Craig Langran Series producer: Tom Colls Sound mix: Gareth Jones Editor: Penny MurphyEmail: peoplefixingtheworld@bbc.co.ukImage: A coconut (Getty Images)

Earthquakes strike suddenly, leaving death and destruction in their wake. But around the world, people are trying to do what they can to make them less deadly.We hear from Haiti, where a seismometer developed for hobbyists is now being used by citizens to build the country’s first earthquake risk map.Over in Zurich, we meet the scientist using tennis balls to buffer buildings in poor countries from shockwaves. And in Indonesia, we find out how a Virtual Reality game is helping students prepare for terrifying tremors.Presenter: Myra Anubi Reporter: Claire Bates Series producer: Tom Colls Sound mix: Hal Haines Editor: Penny MurphyEmail: peoplefixingtheworld@bbc.co.ukImage: A woman in Haiti holding a Raspberry Shake (Credit: Eric Calais)

Heart disease and other cardiovascular diseases are the biggest killer in the world, causing 18 million deaths globally every year.Cardiologists and heart surgeons try to manage heart disease with stents, surgery and drugs, but the organ itself does not heal. Finding a way to regenerate heart tissue has become a holy grail for medicine.Now there is new hope from a strange and pioneering technique from Austria. Doctors there believe that applying shockwaves directly to the heart after surgery dramatically improves patient outcomes.The shockwaves – which are sonic pressure waves, rather than electric shocks – lead to new growth of blood vessels and trick the body’s immune system into action.The BBC’s global health correspondent Naomi Grimley travels to Innsbruck to see the treatment in action.Presenter: Myra Anubi Producer: William Kremer Series producer: Tom Colls Sound mix: Hal Haines and Gareth Jones Editor: Penny MurphyEmail: peoplefixingtheworld@bbc.co.ukImage: Heart surgery
