This is a continuation of the previous exercise, where you had to choose one of the subjects on the list about the environment and living things and write all the words connected to it.

In this exercise, you have to use the words you wrote in the list and make a poster about the topic you have chosen, to make people aware of it. You have to make the emphasis on what causes the problem, what people do on a daily basis that is wrong and makes the issue bigger. After that, focus on what can be done to prevent it or make it better.

Make two columns: one with the words and phrases that show the problem and what causes it. The other column should be the positive words and phrases showing what can be done to make things and the problem better.
