Environmental Impacts of Globalisation

Active learning helps students grasp the abstract concept of transboundary environmental impacts by making distant effects tangible. By simulating real-world flows like haze or shipping routes, students see how globalisation’s environmental costs are not isolated but interconnected across borders.

Activity 01

• Outdoor Investigation Session
• 45 min · Small Groups

Case Study Rotation: Haze Crisis

Prepare stations with sources on 2015 Singapore haze: causes (global palm oil trade), impacts (health, economy), transboundary challenges, solutions (ASEAN agreements). Small groups rotate every 10 minutes, note key facts, then debrief as a class to link to globalisation.

Analyze how global trade contributes to carbon emissions.

Facilitation Tip

During the Case Study Rotation on haze, circulate to listen for misconceptions about local versus distant causes and redirect by asking, 'What evidence in the case contradicts the idea that Singapore’s pollution comes only from Singapore?'

What to look for

Pose the question: 'Imagine you are a Singaporean consumer buying a t-shirt made in Vietnam. What are two environmental impacts of this purchase that occur outside of Singapore?' Facilitate a brief class discussion, encouraging students to reference specific concepts like shipping emissions or factory pollution.

Activity 02

• Outdoor Investigation Session
• 35 min · Pairs

Carbon Emission Mapping: Product Trails

Pairs select a Singapore-imported item like electronics or fruit, trace its supply chain using maps and online emission calculators, estimate carbon footprint from transport, and compare with local alternatives. Share maps on class wall.

Evaluate the challenges of managing transboundary environmental problems.

Facilitation Tip

In Carbon Emission Mapping, remind students to label each trade route with the mode of transport to highlight how shipping and aviation differ in carbon intensity.

What to look for

Provide students with a short case study about plastic waste found on a Singaporean beach, with evidence suggesting it originated from a neighbouring country. Ask them to write two sentences identifying the type of environmental issue and one challenge in holding the source country accountable.

Activity 03

• Outdoor Investigation Session
• 50 min · Small Groups

Stakeholder Role-Play: Resource Summit

Assign roles like factory owner, fisherman, policymaker, NGO rep. In small groups, negotiate solutions to overfishing from global demand, present compromises, vote on best proposal as whole class.

Propose solutions for mitigating the environmental footprint of global production.

Facilitation Tip

For the Stakeholder Role-Play, assign roles at random to push students beyond their initial perspectives and ensure all voices are heard in the negotiation simulation.

What to look for

On an index card, have students list one global commodity Singapore imports and then write one sentence explaining how its global production might contribute to resource depletion or pollution.

Activity 04

• Outdoor Investigation Session
• 30 min · Individual

Data Hunt: Global Trade Impacts

Individuals scour class charts and devices for stats on trade-related deforestation or pollution, log findings in a shared table, then pairs analyse trends and suggest one policy change.

Analyze how global trade contributes to carbon emissions.

Facilitation Tip

During Data Hunt, provide a partially filled table for students who need structure, but leave blank rows for those ready to extend their research to additional commodities.

What to look for

Pose the question: 'Imagine you are a Singaporean consumer buying a t-shirt made in Vietnam. What are two environmental impacts of this purchase that occur outside of Singapore?' Facilitate a brief class discussion, encouraging students to reference specific concepts like shipping emissions or factory pollution.

A few notes on teaching this unit

Experienced teachers approach this topic by balancing factual clarity with empathy for diverse perspectives. Start with concrete examples students already know, like Singapore’s haze experiences, then layer in data to build credibility. Avoid overwhelming students with global statistics; instead, focus on one or two commodities they encounter daily, such as smartphone components or seafood. Research suggests that role-play and mapping activities help students retain complex systems thinking when paired with guided reflection questions that connect their simulations to real-world policy debates.

Successful learning is visible when students can trace environmental impacts across borders and propose cooperative solutions. They should articulate the role of trade in driving pollution and resource depletion and evaluate mitigation strategies critically rather than accepting simplistic fixes.

Watch Out for These Misconceptions

• During Case Study Rotation on haze, watch for students who assume Singapore’s pollution is entirely self-inflicted. Redirect by asking them to examine the case study timeline and identify when external factors, such as wind patterns or regional land use policies, become relevant.

  During the Case Study Rotation, have students annotate a map of Southeast Asia with the haze’s movement and link each annotation to a specific cause, such as slash-and-burn agriculture in Indonesia, to challenge local-only views.

• During Carbon Emission Mapping, watch for students who underestimate the environmental cost of global trade compared to local industries. Redirect by having them calculate the carbon footprint of a single imported product, like a pineapple from Malaysia, and compare it to a locally produced item.

  During Carbon Emission Mapping, ask students to present their most surprising finding from the product trails and explain why shipping emissions exceeded local factory emissions in their calculations.

• During Stakeholder Role-Play, watch for students who propose simple bans as the primary solution to resource depletion. Redirect by asking them to consider the economic impacts on exporting countries and propose alternative strategies like certification or fair trade agreements.

  During the Stakeholder Role-Play, require students to draft a policy that balances environmental goals with economic feasibility, using evidence from their roles’ priorities to avoid oversimplified solutions.
