II. Read the passage, then do the tasks. According to Greenpeace, more than 100,000 sea creatures and a million sea birds die every year after eating plastic or getting trapped in plastic rubbish. Sometimes, when baby turtles get trapped in plastic the shape of their Shell changes when they grow. Some sea creatures make their homes in plastic rubbish, such as the hermit crabs that live on polluted Pacific beaches. Every year, the world produces more than 300 million tonnes of plastic! In a minute, people around the globe use more than a million plastic bags and they throw away more than a million plastic bottles. Where will all this plastic end up? About 10% of it will be recycled, and some will go to landfill, but a lot of it will end up polluting the oceans. Experts estimate that there are already 200 million tonnes of plastic in the world’s oceans, and this will increase by about 7 million tonnes every year. Because plastic isn’t biodegradable it won’t decompose naturally, so all the plastic that we have now in the world will exist forever. That means we’ll need to clean up the oceans if we want to protect our sea creatures. Better still, if we don’t use so much plastic, it won’t end up in the ocean! Experts are warning that if we don’t take urgent action, there might be more plastic than fish in the sea by 2050. A. Match the words to their definitions. 1. getting trapped 2. shell 3. end up 4. landfill 5. clean up 6. biodegradable

2. The hermit crabs living on Pacific beaches die because of plastic pollution.
3. Around the world, people use more plastic bottles than bags.
4. Less than half of plastic bottles and bags end up getting recycled.
5. Plastic rubbish will disappear naturally over time.
