Oysters to the rescue
People Fixing the World

Pollution, overfishing and oxygen depletion are damaging coastal waters across the world. Often fish and other marine life are the victims, but scientists are using one surprising creature to help solve the problem – the oyster.

Oysters eat some chemical pollutants and fight algae blooms, which can have a damaging effect on biodiversity.

A group of teachers and scientists in New York is trying to reintroduce a billion of them into the harbour to make it a healthier, cleaner environment and strengthen the shoreline.

Another team based in France is strapping wires to oysters’ shells around oil rigs to monitor how often they open and close. That gives them vital information about how pollution levels are changing.

Making life easier for older people

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.
