The key answer of exercise 7
The key to exercise solutions in chapter 2.1 - Vocabulary for the textbook Wider World 4 - Student's Book with authors Suzanne Gaynor, Kathryn Alevizos and Carolyn Barraclough from Pearson Education
Question
In Exercise 5, you listened to the first part of the rubbish route. In pairs, finish the description. Use the poster and the Word Friends box to help you.
Answer
Some of the rubbish may stay in the river. Fish or animals may accidentally eat plastic which can kill them. It may get stuck in the river and damage the environment. Other rubbish may flow all the way to the sea and pollute beaches or the oceans. When too much rubbish collects together, it can block out the sunlight and reduce the amount of oxygen in the water.
