Level: Intermediate or higher. Time: 40 mins. This is a great listening exercise based on a podcast from BBC 6 minute English (link included in the lesson plan). Teachers can lead in by asking what happens to plastic when we throw it away. How much of it is recycled? What happens to the rest of it? Students then listen to the podcast two or three times, writing the answers to the questions. This worksheet always generates plenty of discussion (not to mention concern and even shock for what is happening to our planet).
