Threats to Biodiversity

Active learning works well for this topic because biodiversity threats are complex and interconnected. Students need to analyze multiple causes and effects at different scales, which case studies, mapping, and simulations make tangible and memorable.

Activity 01

• Case Study Analysis
• 45 min · Small Groups

Case Study Rotation: Biodiversity Threats

Prepare four case studies on habitat loss, pollution, climate change, and invasives, using Irish examples like hedgerow removal. Small groups rotate every 10 minutes, noting causes, effects, and one mitigation strategy per station. Groups share findings in a whole-class debrief.

Differentiate between various human activities that threaten biodiversity.

Facilitation Tip

During Case Study Rotation, assign each pair a threat and provide a timer to keep discussions focused and equitable.

What to look for

Pose the question: 'If a single native Irish woodland is destroyed for development, what are three ripple effects that could be felt globally?' Guide students to consider impacts on carbon sequestration, migratory bird stopovers, and potential undiscovered medicinal compounds.

Activity 02

• Case Study Analysis
• 30 min · Pairs

Threat Mapping: Local Audit

Provide maps of the school grounds or nearby area. Pairs identify potential threats like litter or invasive plants, mark them, and propose fixes. Compile into a class display for school action.

Analyze how the destruction of one habitat affects the global environment.

Facilitation Tip

For Threat Mapping, give students colored pencils and base maps of their local area to make visible connections between threats and specific locations.

What to look for

Provide students with a list of human activities (e.g., building a new road, intensive farming, plastic packaging disposal, planting non-native trees). Ask them to categorize each activity as a primary threat to biodiversity and briefly explain why for two examples.

Activity 03

• Case Study Analysis
• 35 min · Pairs

Debate Pairs: Human vs. Natural Causes

Assign pairs to argue if threats are mostly human-made or natural, using evidence cards on Irish biodiversity. Switch sides midway, then vote as a class on strongest points.

Predict the long-term impacts of biodiversity loss on human societies.

Facilitation Tip

In Debate Pairs, require each student to cite at least one source during their argument to strengthen evidence-based reasoning.

What to look for

On an index card, have students write the name of one invasive species found in Ireland. Then, they should list two ways this species threatens native biodiversity and one potential long-term consequence for the Irish environment or society.

Activity 04

• Simulation Game
• 40 min · Small Groups

Simulation Game: Invasive Spread

In small groups, use cards to simulate species interactions where invasives displace natives. Track biodiversity decline over 'generations' and discuss prevention.

Differentiate between various human activities that threaten biodiversity.

Facilitation Tip

Run the Simulation Game in a large open space so students can physically model the spread of invasive species.

What to look for

Pose the question: 'If a single native Irish woodland is destroyed for development, what are three ripple effects that could be felt globally?' Guide students to consider impacts on carbon sequestration, migratory bird stopovers, and potential undiscovered medicinal compounds.

A few notes on teaching this unit

Teachers should connect abstract concepts like climate change to local examples first, then expand to global systems. Use predictions and modeling to help students see cause and effect, and avoid letting discussions remain theoretical. Research shows that students grasp interconnectedness better when they work with real data and local cases before abstracting patterns.

By the end of these activities, students will distinguish between human and natural threats, explain how local actions have global impacts, and justify why biodiversity matters for ecosystems and society. Evidence will come from their discussions, maps, debates, and simulations.

Watch Out for These Misconceptions

• During the Case Study Rotation activity, watch for students who summarize threats narrowly as only affecting animals.

  Use the case study handouts to prompt students to trace how plant loss disrupts pollinators and soil health, then have them add these connections to a class concept map displayed during the rotation.

• During the Simulation Game: Invasive Spread activity, watch for students who assume invasive species do not harm native plants.

  Have students observe the simulation board closely after each round to note how invasive species reduce the survival of native plants, then discuss why this matters for Irish peatlands and hedgerows during the debrief.

• During the Threat Mapping: Local Audit activity, watch for students who think climate change impacts biodiversity only far away.

  Ask students to mark local sites where climate-related changes are visible, such as flooded fields or heat-stressed hedgerows, then connect these to global data in a follow-up discussion using their maps as evidence.
