Safety in the sun: Dispensing free sun cream to Miami Beach

Up to 3 million skin cancer tumours are identified globally each year.

But this number will continue to rise, not only as the atmosphere's protective ozone layer is broken down - which allows more harmful UV rays to reach us on the Earth's surface - but also as we spend more time in the sun.

One way we can reduce our risk of skin cancer is using UV blocking sun screens. In sunny Miami Beach, USA, the city has taken a step forward in making sure people can access this when they are out and about in the city, as Beatriz Diez reports.
