Introduction (10 - 15 minutes)

The teacher will:

1. Remind students of the previous lessons on ecosystems, emphasizing the role of balance and interdependence in sustaining life. For instance, the teacher can ask questions like "What do you remember about the role of producers, consumers, and decomposers in an ecosystem?" or "How do changes in one part of an ecosystem affect the rest of it?" to jog their memory and set the stage for the new topic. (3 - 4 minutes)

2. Present two problem situations as starters to the lesson:

   • "Imagine a town that relies on a single industry, like fishing. What could happen if the fish population decreases due to overfishing?" This scenario will highlight the importance of economic sustainability and the potential consequences of not considering environmental factors.
   • "Think about a city where the majority of people rely on cars for transportation, leading to high levels of air pollution. How could this affect the health and well-being of the residents?" This real-world example will illustrate the link between environmental and social sustainability. (3 - 4 minutes)

3. Contextualize the importance of the subject by discussing real-world applications and current events. For example, the teacher can mention how companies are increasingly adopting sustainable practices to reduce their environmental impact and improve their long-term viability. They can also mention global initiatives like the United Nations' Sustainable Development Goals, which aim to address some of the world's most pressing issues through sustainable development. (2 - 3 minutes)

4. Grab the students' attention by sharing two intriguing facts or stories related to sustainability:

   • "Did you know that some companies are now using 'cradle to cradle' design principles, where products are designed to be fully recycled or biodegradable, so that there is no waste? This is a great example of how sustainability can drive innovation!"
   • "In the 1960s, a small Pacific island called Nauru was one of the richest countries in the world due to its phosphate deposits. However, after unsustainable mining practices depleted the deposits, the country's economy collapsed. This is a stark reminder of the importance of long-term thinking and sustainable practices." (2 - 3 minutes)

5. Introduce the topic of sustainability, explaining that it is not just about protecting the environment, but also about finding ways for people and the economy to thrive in harmony with the planet. The teacher can use a visual aid, such as a diagram showing the three components of sustainability, to help students understand the concept. (2 - 3 minutes)
