Provide the students with a copy of the Sustainability in Occupations Worksheet. To revise the content of the previous lesson, allow the students to complete Questions 1 and 2 independently.

Watch the Sustainability Easily Explained video on YouTube. After watching, ask the students:
- What were some of Peter's sustainable actions?
- What were some of the unsustainable actions that were mentioned in the video?
- Do you think that the human race acts sustainably or unsustainably? Why do you think this?
Allow the students to use the ideas stimulated by the discussion to answer Question 3 on the worksheet.

Read through Question 4 as a class. Look at the table on the second page and discuss the example. Ensure that the students understand the requirements of the task and answer any questions they may have.
In small groups, pairs or individually, allow the students to complete the table on pages 2-4 of the worksheet. Alternatively, allocate an occupation to each pair or group to complete. Once the students have finished the task, allow each group to share their ideas with the rest of the class.

Discuss the task as a class. Ask the students:
- Did you find any occupations particularly easy or difficult to complete? Which ones?
- Was it easier to think of factors that support sustainability or oppose sustainability?
- Can you think of ways in which you support and oppose sustainability in your own life?
