People Fixing the World

We rely on space for our communications, weather monitoring and security. Yet rising levels of space junk increase the risk of collisions, putting these things at risk.

This week we are heading to a space lab in the UK to meet the scientists building a special waste collector that will clean up defunct satellites. We’ll also be heading to the Himalayas to see how an innovative project is training sherpas in Nepal to clear trash off the mountains using drones.

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 hear about the start-up using coconut to keep fish, fruit and vegetables cool for longer without using any plastic.

A short online test that reveals attitudes, opinions and thought processes is being used to help decide whether to give people loans. The idea is to use psychometric tests to give people with little or no credit history a better chance of getting support and investment. New ways of providing financial services are needed because 1.7 billion people have no access to any kind of formal banking facilities, according to the World Bank. Known as the unbanked, they deal only in cash. This can make it harder to reduce poverty, save money or invest for the future. Cheap mobile phones and good network coverage in Nigeria are also transforming the lives of people who previously only dealt in cash.

Can companies operate better without managers? We hear from people who’ve got rid of managers and say it has helped them do a better job, made them happier and saved money.

But there are pitfalls, too. Co-ordination and hiring talent for what are usually considered top management jobs can be a challenge when there’s no traditional hierarchy.

Old ships, powered by the wind, are sailing small amounts of cargo around the world again to help cut pollution. Some of them were built more than 100 years ago. The shipping industry moves 80% of traded goods around the planet. But the diesel engines that propel modern cargo ships through the oceans burn the dirtiest type of fuel.

Nick Holland speaks to sailors and brokers who, for the sake of the environment, are breathing new life into these vintage vessels. And he hears how new types of sails could get monster-sized modern cargo ships using the wind as well. Producer / Reporter: Nick Holland
