Activity 2 Read the passage and find out whether plastic has made life better or worse.
Plastic good or bad?
When plastic was invented around the 1860s, it was considered an amazing material. It was light, easy to shape, long-lasting and cheap. It quickly replaced wood and other natural materials. Many people believed plastic would make life better. Back then, some people even saw plastic as an “environmental hero”.
Not surprisingly, plastic has now filled our lives We can find it in bags, bottles, toothbrushes, gloves, mobile phones, cars, houses... you name it. It is certainly convenient and has thousands of uses. Despite all this, it has slowly and quietly shown its dark side. Plastic waste was first seen in the oceans in the 1960s. Since then, it has become a danger to sea animals. Some animals, such as whales, eat it by mistake and die. The former “hero” kills more than 100,000 sea animals every year. By 2050, there could be even more plastic than fish in the sea by weight.

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! Even humans are eating plastic waste! On average, we eat five grams of plastic a week. That’s a whole bank card! Tiny pieces of plastic are found in the air we breathe. They can be carried around by the wind. There is even plastic “snow” at the North and South Poles. On “Planet Plastic”, there is no place free from this.
Plastic waste is hard to deal with. It may take hundreds of years to break down. Therefore, hiding the waste in the ground doesn’t solve the problem. Burning it also produces thick smoke that causes air pollution.
Plastic makes life easier for many people, yet it brings long-lasting troubles to our planet. Our choices today change the world tomorrow. With no Planet B to turn to, we must think clearly and use plastic wisely.

Think & share
1. Which problem of plastic do you find most shocking? Why?
The most shocking plastic problem is that it’s almost impossible to break down naturally. It stays in the environment for hundreds of years, polluting the sea and land. It brings long-lasting troubles to our planet.
2. Do you think humans will ever stop using plastic? Why or why not?
I don’t think humans will ever stop using plastic completely. Plastic is cheap and useful in many areas, and we have no perfect replacements yet.
Learning to think for question 2 To think about the future of plastic, you should consider things like environmental problems, new technologies and how people feel about plastic.
