When you go shopping ,people in the shop give you at least one plastic bag to carry what you’ve bought. They are so common that we don’t often give them a second thought. There may come a time when plastic shopping bags are no longer used.
A small town called Coles Bay, in Tasmania, an island off the south coast of mainland Australia, is making itself an environmental role model by becoming the country’s first plastic bag-free town.
Every year Australians use more than 6 billion plastic bags. More than a half of these come from supermarkets. Since it takes years for the bags to biodegrade(生物分解),tens of millions of them end up pollution the environment. They kill about 100 000 sea-birds and animals every year, because the sea-birds and animals mistake the bags for food.
Pollution caused by plastic bags is a big headache for countries all over the world. In China’s capital alone, an average(平均的)of 6 billion plastic bags are used every single day.
