People believed plastic would make life better and it was an “environmental hero”. It was invented around the 1860s. Because it was light, easy to shape, long-lasting and cheap. Read paragraph 1 and answer 1.7.2013 Let's read Paragraph 1 carefully. When was plastic invented? Around the 1860s. Why was it considered amazing? Because it was light, easy to shape, long-lasting and cheap. Many people even saw plastic as an "environmental hero". It quickly replaced wood and natural materials. But wait - is plastic still a hero today? Let's find out in the next paragraphs. ‹#› 1, When was plastic waste first seen in the oceans? 2, How many sea animals were killed every year? Plastic waste was first seen in the oceans in the 1960s More than 100,000 sea animals. While-reading Read paragraph 2 and answer 1.7.2013 Now we see the dark side of plastic. When was plastic waste first seen in the oceans? In the 1960s. How many sea animals die every year? More than 100,000. And by 2050, there could be even more plastic than fish in the sea by weight. Whales and other sea animals eat plastic by mistake and die. The former "hero" has slowly shown its dark side. ‹#› 1, How are these animals affected? Birds Bears Cows Humans 2, Is it hard to deal with the problems ? Why ? While-reading Read paragraph 3-4 and complete wings get tied in plastic lines heads get stuck in plastic bins mistake plastic bags for food eat 5 grams of plastic a week Yes, it is. It may take hundreds of years to break down. Hiding waste in the ground doesn't solve the problems. Burning it produces thick smoke that causes air pollution. 1.7.2013 Plastic is also causing problems on land. Birds' wings get tied in plastic lines. Bears' heads get stuck in plastic bins. Cows mistake plastic bags for food. And even humans are eating plastic waste! On average, we eat five grams of plastic a week. That's like eating a whole credit card! Plastic pollution is not just an ocean problem - it's everywhere, including on land and in our own bodies. ‹#› 1, What was the writer's opinion about the plastic? Plastic makes life easier, yet it brings long-lasting troubles to our planet. While-reading Read paragraph 5 and think 1.7.2013 Plastic waste is really hard to deal with. Why? Because it may take hundreds of years to break down. So hiding the waste in the ground doesn't really solve the problem. And burning it also produces thick smoke that causes air pollution. It's a real dilemma - what can we do with all this plastic? This is why we need to think carefully about how we use plastic. ‹#› a. To remind readers that plastic is convenient and useful. b. To call on people to use plastic wisely and protect our planet. c. To argue that we should stop using plastic completely.
