Watching news about the environ-ment on TV can be depressing. Whether it’s climate change or the disappearance of another animal species， it seems as if there’s nothing we can do to change things. The problems seem so big that it’s difficult to imagine how we as individuals can do anything about them. Rebecca Hosking， however， thought differently. Her story can be an example to all of us.

Rebecca is a wildlife camerawoman and she was filming a documentary for the BBC in the Pacific Ocean when she saw something that made her cry： hundreds of dead birds that had died because they had accidentally eaten some of the tonnes of plastic that is thrown into the sea each year. Beaches in Honolulu and other Pacific islands， which should have been some of the most beautiful places in the world， were covered with plastic toys， bottles， keyboards， pens， cigarette lighters—every plastic thing you can think of. As well as seabirds， other animals were suffering because of thrown-away plastic： whales， dolphins， seals， turtles.

At this point most of us would have felt sad and helpless but Rebecca decided she had to do something. Back at home she thought about what she could do to help solve the problem of thrown-away plastic. In her home town of Modbury in the south-west of England she showed her film from the island to local shopkeepers and asked them if they could do one thing to help. She asked them to stop using plastic bags in their shops.

Rebecca expected the shopkeepers to refuse. Plastic bags are used everywhere in Britain—every supermarket， every corner shop—and customers expect to be given something to carry their shopping in. The numbers are amazing. Britain uses nearly 8.5 billion plastic bags each year. That’s 300 for every man， woman and child in the country. And the bags can take hundreds of years to break down because they are chemical rather than natural， so each year the sea and the environment become more and more polluted.

To Rebecca’s surprise， the shopkeepers agreed and Modbury became the first plastic-bag-free town in Britain. Shops offered reusable cotton bags or biodegradable bags. People in the town got used to taking a shopping bag with them to the supermarket—just like their grandparents had done before plastic bags were invented.

In the months that followed， other towns in Britain followed Modbury’s example. The small town of Hebden Bridge in northern England became the second plastic-bag-free town when four women there saw Rebecca’s film and decided to act. Like Rebecca， they expected opposition from shopkeepers but found that they were pushing an open door. ‘It’s a no-brainer，’ says one of the Hebden Bridge ‘bag ladies’. ‘Plastic bags are not greatly loved. They’re useful but we don’t really need them and people are happy to help try to change things.’

More and more towns around Britain and around the world are becoming plastic-bag-free. Now the ‘bag for life’ is part of the national culture， and the task of reducing the use of plastic bags has become law： since October 2015， all shops in the UK must charge five pence for each plastic bag used by each shopper， no matter how generous your spending！ It’s not enough， of course， but it’s a start. It also shows us that when we watch the news and feel helpless there is something we can do and that one person can make a big change with a strong enough belief.
