Often described as underwater rainforests and the “lungs of the ocean”, kelp forests line as much as 25% of the world’s coastlines. They provide important shelter and food for fish and other marine life, and are vital for our oceans’ ecosystems. However kelp is under severe threat because of climate change, warming seas and overfishing. We look at projects in California aimed at stemming the decline of kelp including how scientists are growing it in a laboratory to be planted at sea as well as tackling a key cause of kelp degradation - sea urchins.

Premature babies often need a lot of expensive specialised care - but that isn’t always available. So, doctors in Colombia are teaching mothers to look after their babies in a similar way that kangaroos look after their own young.

It’s called "kangaroo mother care" and instead of being in an incubator, babies are wrapped tightly against their mother’s skin.

The technique was developed in Bogota in the late 1970s as a response to overcrowding in hospital maternity units. There weren't enough incubators and around 70% of premature babies didn’t survive.

Doctors started using this simple skin-to-skin method. They found it wasn't only saving babies but was also helping them to thrive. Now, kangaroo care has spread around the world.

The fashion industry is the third largest manufacturing industry in the world consuming huge amounts of the world’s resources and contributing to greenhouse gas emissions. But some innovators are trying to make the industry more sustainable. We discover how old fire hoses in the UK have been diverted from landfill and turned into fashionable bags and accessories. Plus we visit Mongolia to find out about a new luxury material made from yak hair. It's an eco-friendly replacement for cashmere which comes from goats who are causing desertification.

Learning to read empowers people, reduces poverty and increases their job chances. Yet more than 700 miliion adults are illiterate, the majority of them women. We look at innovations to help adults learn how to read from flatpack classrooms in flood-prone regions of Bangladesh, to an app teaching tens of thousands in Somaliland. Plus how adults in the UK are improving their reading skills thanks to an army of volunteer teachers using a method developed in prison.

We all know about the power of music to change our mood or to make us move. But an increasing body of evidence is showing that music has an amazing ability to help us heal. In this programme we are going to meet people working at the cutting edge of music therapy. We find out about the innovative system that uses music to help people with dementia live at home for longer. We will see how using songs and rhythms is helping people with Parkinson’s move more freely. And in a refugee camp in Uganda we meet the teachers using music to bring people together and overcome trauma.

Transforming the global food system is vital in the fight against climate change. Currently, food production accounts for a third of all greenhouse gas emissions. At the same time, the food system also fails to properly nourish billions of people worldwide.

In this edition of People Fixing The World we’re looking at high and low tech solutions to transform the ways we produce and consume food to make it greener and more equitable.

In London, we visit a startup company making cheese from genetically modified microbes rather than cattle, in a bid to make dairy production better for the planet.

And in Philadelphia we look at how planting fruit and nut trees in ‘food forests’ is tackling hunger by providing access to healthy, nutritious food for low-income communities across the city.

Could psychedelic drugs help in the treatment of mental health conditions? We look at pioneering research into psilocybin, the active ingredient in so-called magic mushrooms. We visit a clinic in Oregon, the only state in America where the use of psilocybin in therapeutic sessions is legal and hear from one patient who says it's the only treatment she's ever had that makes a difference to her depression. And we hear about some of the widespread concerns that widening access to such drugs could have.

Whistleblowers - they're the good guys right? The ones who speak truth to power and have films made about the heroic stands they took? Sometimes. Often the people who speak up in the workplace are ignored or shut down. Worse still they're often bullied or harassed or end up losing their jobs. They're the ones you never hear about.

This week we hear about two projects that are encouraging people to speak up about wrongdoing at work and how they're improving people’s work environment, saving time, money and even saving lives.

Schools across Senegal have discovered a clever way for children to surf the web even when there isn't any signal.

They're using a special WIFI hotspot which works without an actual internet connection, so students and teachers can access all the relevant bits of the web, offline.

Around the world, innovators are coming up with solutions like this - all designed to get children learning. We also hear from an entrepreneur revolutionising how science is taught in Ghana and a night school in Pakistan for children not in formal education.

Australia used to be one of the most linguistically diverse places, with over 200 languages. Today, many of Australia’s indigenous languages are considered “highly endangered”. Inspired by his native language, Hebrew, Ghil’ad Zuckermann is a linguistics professor who is on a mission to revive Australia’s dead and endangered languages, painstakingly piecing them back together from historical documents. We speak to Ghil’ad and Shania Richards from the Barngarla community, whose language is being brought back from the brink.

Barcelona in Spain is famous for its beautiful streets, lined with tall apartment buildings. But the architecture is a problem for many people who have lived for years in upstairs apartments but who now find the stairs unmanageable.

In 2008, a survey found that in one district there were 300 people who could not leave their homes alone. A group of volunteers decided to do something about this and got hold of a special wheelchair with caterpillar tracks, so it can be used to take people up and down stairs. After an initial pilot scheme they launched a local service called “Let's Go Down to the Street”, to help elderly residents go shopping or meet up with friends. Sixteen years on, the service is offered across the city.

Plus, we visit a home for senior citizens in an unlikely location: a university campus. The Mirabella complex at Arizona State University in the US offers its residents the chance to sample the college lifestyle – from lectures to shows and sports fixtures.
