When Rebecca Hosking saw the devastating effect of plastic bags on marine life in Hawaii for a BBC documentary that she was filming, she was determined to do something about it. Back at home in Modbury, Devon, she suggested in the pub one evening that the town should become a plastic-bag-free zone. Six months later, it has happened and carrying a plastic bag in Modbury is now seen as anti-social behaviour. At least 50 towns and cities are following suit, with Mull, Arran and Guernsey all racing to become the first plastic bag-free island in the world. You can read about how Rebecca did it here.

It’s amazing what one woman can initiate and what one conversation in a pub or over a dinner table can lead to. Who are the women who have inspired you? And what are the dreams that you need to speak into being?
