From beavers in the UK to bison in Romania and jaguars in Argentina, ecologists around the world are reintroducing animals that once flourished in particular areas. The theory is, if done correctly, they can boost biodiversity and restore ecosystems with benefits ranging from reducing forest fires to tackling invasive species. But the strategy is controversial. Opponents say some species are no longer suited to certain areas and cause conflict with farmers, adding there is little evidence it works. Proponents admit some well-meaning projects haven’t worked in the past, but insist properly planned rewilding, which has involved all the stakeholders from the start, can be very successful. We take a close look. Presenter: Myra Anubi

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.

Restoring California's underwater forests

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. Presenter: Myra Anubi

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. Presenter: Myra Anubi
